CHAPTER 1
INTRODUCTION
A study on jatropha (Jatropha curcas) indicates that it can produce more than 30
percent oil yield and that it is more environment-friendly as fuel source than diesel.
Based on an article in the Philippine Daily Inquirer, Energy Secretary Jose Rene
Almendras recently disclosed that the Arroyo administration had already spent P1 billion
of a P1.4 billion allocation for the project, covering the cost of planting some 4,000
8/3/2019 Bagong Data
2/40
hectares of land with jatropha plant. While established studies had found that jatropha
oil could be converted into methyl ester, a material suitable as blend for diesel fuel
according to DOST, commercial production is said to be not viable. (Tarra Quismundo,
November 2011). According to the United Nations Food and Agriculture Organization,
the Jatropha fruit contains 62.5 % seeds.
Lumbang (Aleurites moluccana) or also known as candlenut is a flowering tree
and distributed throughout tropical regions. It grows to a height of 15-25 meters and has
a nut that is round for about 4-6 cm and the seed (kernel) inside has a very hard seed
coat (nutshells) and has a high oil content, which allows its use as a candle. According
to the research made by Hong TD et al., the lumbang kernels yields 57-80 percent of
inedible oil. According to Bureau of Agricultural and Statistics the production of lumbang
seeds in San Alfonso, Cavite has an average of 50-150 kilograms per tree annually.
Quick Drying oils are any group of oily, organic liquid that, when applied as a thin
coating, can absorb atmospheric oxygen and polymerize, forming a though and elastic
layer. These quick drying oils are being used in the paint industry as a raw material to
quick drying enamel products, raw material in the production of varnish, and in nail
polish enamels. The processes involved in the production of Quick Drying Oil includes
the extraction of the oil from the lumbang kernel and tuba tuba seeds, degumming,
alkali refining, bleaching, and the heart of the process polymerization.
From these cases, the researchers are triggered to formulate a study entitledExtraction of Linoleic Acid from Tuba-tuba (Jatropha curcas) and Lumbang( Aleurites moluccana) for the production of Quick Drying Oils via CondensationPolymerization

RATIONALE
The thousand hectares of planted tuba-tuba for the jatropha biodiesel project
turned out to be a problem as the plan was considered to be commercially unviable.
Lumbang seeds are unutilized agricultural material abundant here in the country.
Linseed, the most commonly used raw material for quick drying oils is not native
in our country. In 2009, 80,865 kilograms of linseed oil were imported to the Philippines.
In an effort to supply this demand without resorting to importation, and to minimize
waste brought about by tuba-tuba and lumbang, this research is projected.
The proposed study, pertaining to producing quick drying oil tuba-tuba and
lumbang looks forward to providing a way in which the said agricultural materials will be
of use. The manufacture of a oilseed industrial plant will also prove its significance in
the countrys economy.

STATEMENT OF THE PROBLEM
8/3/2019 Bagong Data
6/40
Lumbang (Alurites moluccana) kernel represents an agricultural crop with
importance as it is being used as one alternative in candles and often called candlenut.
An interview made by the researchers revealed that years and years ago when there is
no electricity yet, the oil was being extracted in the lumbang kernel using a piece of
cotton. Mr. Dimacuja, a resident of Barrio Sinaliw San Alfonso, Cavite told the
researchers that the oil extracted from the lumbang kernel was being ignited and will be
a source of light. But upon the discovery of electrical technology lumbang kernel was
left unutilized, scattered in the ground, and if not germinated will be rotten. Meanwhile
according to ABS-CBN news on the 4th of November 2011, the Department of Energy is
claiming the Arroyo administration wasted P1.4 billion on a project to cultivate the
jatropha (Jatropha curcas) plant, which was hailed as a future source of fuel.
More than 4,000 hectares of idle land was planted with the Jatropha curcas
during the Arroyo administration. The program has been running for several years now,
but there is one problem according to the Aquino administration - jatropha is not
commercially viable. In Pila, Laguna, there used to be 5,000 to 6,000 jatropha trees
planted in this 2-hectare property. The researchers aimed to conduct further studies on
the other uses of jatropha and jatropha oil, aside from petroleum additives.
With all these considerations, the researchers are triggered to use the Lumbang
and Tuba Tuba Seeds as the primary raw material: which are considered as unutilized
waste. The researchers indulge in this study entitled Extraction of Linoleic Acid from
Tuba-tuba (Jatropha curcas) and Lumbang ( Aleurites moluccana) for the
production of Quick Drying Oils via CondensationPolymerization

SIGNIFICANCE OF THE STUDY
To the Students
This study would give an insight to the students of the notion such that crops like
tuba-tuba and lumbang could be a multipurpose crop providing both energy and feed
(as a raw material) which, in one way or another, could relate it to their future research
studies in cases like utilizing the same raw material for the production of a different
product and vice versa.
To the Nation
By utilizing tuba-tuba oil and lumbang oil for the production of useful products,
such as Quick Drying Oil, can respectively be an alternative use for the raw material to
paint, varnish and nail polish. This could possibly be a way to make more job
opportunities possible.
To the ChE Profession
Advance researches and process developments from Chemical engineers about
this study, which explores tuba-tuba and lumbang oil as a viable source of Quick Drying
Oil, could boost up the country's economic and scientific development.

SCOPE AND LIMITATIONS
This study entitled Extraction of Linoleic Acid from Tuba tuba (Jatropha
curcas Linn.) and Lumbang (Jatropha Mollucana Linn.) for the Production of
Quick Drying Oil via Condensation Polymerization centers on tuba-tuba seeds and
lumbang kernels as raw materials for the production of quick drying oil. The product is
proposed to be an alternative to linseed oil. For the experimental part of the research,
tuba-tuba seeds are obtained from LOCATION and lumbang kernels are from San
Alfonso, Cavite. The production is composed of four steps; (1) Preparation and
Conditioning of Raw Materials, (2) Extraction, (3) Refining and (4) Polymerization.
A market study was included to institute feasibility of the product sales. Analysis
of the historical and projected demand and supply was done for the market allocation.
For the marketability of the quick drying oil, product distribution techniques were also
accounted.
Technical study was also integrated in order to have the required specifications
and designs of the necessary equipment for the process. Careful selection and design
of essential equipment for the production of cellophane was included in this study. Part
of this study was the wastewater facility for the treatment of process wastewater. Also,
the appropriate instrumentation and process control and piping system fitting the actual

F. Analysis:
In this procedure, five different ratios of raw materials were used to determine the
appropriate ratio that will give the desired property of drying oil but not very fast
that may cause difficulty in manufacturing process. Obviously, the greater the
proportion of lumbang to tuba-tuba (1:2 and 1:3) yielded the maximum amount of
oil but the consequence was that they easily solidifies upon transferring from one
container to another right after their volume and mass were recorded.
On the other hand, the greater the proportion of tuba tuba oil to lumbang, the
slower the drying of oil since tuba tuba oil dries much slower than the lumbang
oil. In this case, 2:1 is the chosen one although yield has lower volume compared
to 3:1.
G. Conclusion:
The 2:1 ratio of raw materials is the appropriate ratio that will yield the desired
property of the oil.

The oil obtained was proven to be acidic in nature. This is due to the presence of
free fatty acids (FFA) in the solution. Based on the results, a minimum of 10
minutes is enough to neutralize most of the FFAs in the sample. A significant
amount of soap was recorded. This is may be accounted to other mechanisms
involved aside from neutralization such as hydration of phophatides by the water
in the lye and adsorption of colour elements on to soap. Further neutralization
results almost negligible changes in the mass of solutions which also indicates
that the solution almost reach a pH of neutrality.
G. Conclusion:
10 minutes is the minimum time required to neutralize the oil sample given a
specific amount of lye going to be add.

Tuba-tuba
Jatropha curcas L. is found throughout the Philippines. In fact, different regions
have their own common name for Jatropha. In the Tagalog region it is known as tubing-
bakod, tuba and sambo. Among the Bicolanos, it is called tuba and tuba-tuba; in
8/3/2019 Bagong Data
30/40
Pangasinan and Nueva Ecija, it is called tagumbao; tawa-tawa in Ilocos and kalunay in
Cagayan Valley. In the Visayas and Mindanao, it is also known as tuba-tuba; kasla
among the Ilonggos and tangan-tangan in Lanao region.
Jatropha is a drought resistant perennial shrub or small tree that has an
economic life of up to 35 years and can live for 50 years. It grows fast, with little or no
need for maintenance and can reach a height of 3 to 8 meters.
It has a smooth gray bark which exudes whitish color, watery, latex when cut. The size
of the leaves ranges from 6-15 cm in length and width. The leaves are green to pale,
alternate to sub-opposite with 3 to 5 lobes. It sheds leaves in the dry season and
rejuvenates during rainy season.
Jatropha curcas is a tropical and subtropical plant. It grows almost anywhere even on
sandy, gravelly and saline soils and does well on high temperatures. Jatropha is well adapted
to marginal soils with low nutrient content but the use of organic fertilizer would result to
higher yield. Its water requirement is extremely low and can stand long periods of
drought by shedding most of its leaves. It grows best when planted at the start of the
rainy season.
Much research has been conducted on the
composition and properties of Jatropha seeds by
others ((Openshaw, 2000, 1-19), (Heller, 1996),
(Henning, 2004) and (Sirisomboom, 7 A.D.)).
These studies also provide insight in the
possibilities of using Jatropha oil for uel purposes.
Knowledge of the physical and mechanical
properties of Jatropha is required for adequatedesign of machines for de-hulling, drying and pressing of the seeds. Restrictions on how
to store the seeds are linked to these properties. Mechanical properties such as rupture
force and energy required for rupturing fruit, nut and kernel provide insights on how to
adapt the pressing process to Jatropha seeds. The seeds contain 27-40% oil (average:
34.4%). The seeds are also a source of the highly poisonous toxalbumin curcin.

Jatropha Curcas or "Tuba tuba" is a non-edible plant that grows mostly in tropical
countries like the Philippines. Jatropha Curcas is resistant to drought and can easily be
planted or propagated through seeds or cuttings. It starts producing seeds within 14
months, but reaches its maximum productivity level after 4-5 years. The plant remains
useful for around 30-40 years.
As potential source for biodiesel, the Jatropha plant can produce an oil content of
30-58%, depending on the quality of the soil where it is planted. Its seeds yield an
annual equivalent of 0.75 to 2 tons of biodiesel per hectare.
Based on a March 2006 study commissioned by the Department of Science and
Technology (DOST), potential areas for jatropha plantation in the Philippines is at 2
million hectares. If farmers will be encouraged to plant even in field boundaries or
hedges and to practice intercropping, a total of 5 million hectares can be utilized for the
jatropha plant.
With 1.1 million hectares dedicated to jatropha, 5.5 million metric tons (MMT) of
biodiesel feedstock can be produced. Five million hectares can yield up to 25 MMT of
biodiesel feedstock.
At present, a total of 360 hectares of land are planted with Jatropha in the
country, found in the following areas: 200 hectares in General Santos, 27 hectares in
Camarines Sur, 120 hectares in Fort Magsaysay, Nueva Ecija, 5 hectares in Dacong
Cogon, Negros Occidental, and aside from locally-grown jatropha in Quezon Province.

Lumbang
8/3/2019 Bagong Data
33/40
Lumbang is a large tree reaching a diameter of 80-150 cm with an average
height of 24.0 m in the dense stand and 21.4 m in the open stand. The outer bark is
grayish white, while the inner bark is reddish when cut and slightly exuding a reddish
sap when wet.
The seeds are only about 3 cm long and 3.5 cm broad with 1 or 2 hand shells.
The shell of the seed is very hard, rough, ridged and about 2.5 mm in thickness. Within
the seed is a white, oily and fleshy kernel consisting of a very thin embryo surrounded
by a large endosperm.
Lumbang is also grown in plantations as shade for growing plants. The wood is
used in the manufacture of matches and wooden shoes. The juice of the nuts can be
taken internally to eradicate worms. Its seeds serve as mild purgative.
Lumbang is found throughout the Philippines at low and medium altitudes in
secondary forests. It is widely planted in the provinces of Cavite and Laguna. It
apparentlygrows well in a variety of tropical climates. It grows in dry localities as well as
in regions where rainfall is very heavy and in provinces where rainfall is fairly well
distributed. In the Philippines, it grows in 6 provinces with climatic type 1 (6 months dry
from November-April and the rest wet season) namely, Antique, Cavite, Laguna,
Zambales, Cebu, and Davao.
Solvent Extraction
Solvent Extraction is a process which involves extracting oil from oil-bearing
materials by treating it with a low boiler solvent as opposed to extracting the oils by
mechanical pressing methods (such as expellers, hydraulic presses, etc.) The solventextraction method recovers almost all the oils and leaves behind only 0.5% to 0.7%
residual oil in the raw material. In the case of mechanical pressing the residual oil left in
the oil cake may be anywhere from 6% to 14%. The solvent extraction method can be
applied directly to any low oil content raw materials. It can also be used to extract pre-
pressed oil cakes obtained from high oil content materials. Because of the high
8/3/2019 Bagong Data
34/40
percentage of recovered oil, solvent extraction has become the most popular method of
extraction of oils and fats. Fat is one of the essential components of the human diet,
therefore the demand for oils and fats are increasing with the in-crease in population
and standards of living. Today large quantities of oil cakes such as peanut, cottonseed,
linseed, kardiseed, neem, castor, mowha, copra, sunflower, etc. are extracted. Direct
extraction of rice bran, salseed and soybean is also used. Solvent Extraction is basically
a process of diffusion of a solvent into oil-bearing cells of the raw material resulting in a
solution of the oil in solvent (www.srsbiodiesel.com/SolventExtraction.aspx).
Alkali Refining
The nonglyceride components contribute practically all the colour and flavour to
fats. In addition, such materials as the free fatty acids, waxes, colour bodies,
mucilaginous materials, phospholipids, carotenoids, and gossypol (a yellow pigment
found only in cottonseed oil) contribute other undesirable properties in fats used for
edible and, to some extent, industrial purposes.
Many of these can be removed by treating fats at 40 to 85 C (104 to 185 F)
with an aqueous solution of caustic soda (sodium hydroxide) or soda ash(sodium
carbonate). The refining may be done in a tank (in which case it is called batch or tank
refining) or in a continuous system. In batch refining, the aqueous emulsion of soaps
formed from free fatty acids, along with other impurities (soapstock), settles to the
bottom and is drawn off. In the continuous system the emulsion is separated with
centrifuges. After the fat has been refined, it is usually washed with water to remove
traces of alkali and soapstock. Oils that have been refined with soda ash or ammonia
generally require a light re-refining with caustic soda to improve colour. After water
washing, the oil may be dried by heating in a vacuum or by filtering through a dry filter-
aid material. The refined oil may be used for industrial purposes or may be processedfurther to edible oils. Usually, the refined oils are neutral (i.e., neither acidic
nor alkaline), free of material that separates on heating (break material), lighter in
colour, less viscous, and more susceptible to rancidity (www.britannica.com).

Chemical Composition andAntioxidant Properties of Candlenut Oil Extracted by
SupercriticalCO2
(Siddique, B. M., et. al., 14 April 2011)
Candlenut oil was extracted using supercritical CO2 (SC-CO2) with an
optimization of parameters, by the response surface methodology . The ground
candlenut samples were treated in 2 different ways, that is, dried in either a heat oven
(sample moisture content of 2.91%) or dried in a vacuum oven (sample moisture
content of 1.98%), before extraction. An untreated sample (moisture content of 4.87%)
was used as a control. The maximum percentage of oil was extracted from the heat-
oven-dried sample (77.27%), followed by the vacuum-oven-dried sample (74.32%), and
the untreated sample (70.12%). At an SC-CO2 pressure of 48.26 Mpa and 60 min of
extraction time, the optimal temperatures for extraction were found to be 76.4 C, 73.9
C, and 70.6 C for the untreated, heat-oven-dried, and vacuum-oven-dried samples,
respectively. The heat-oven-dried sample contains the highest percentage of linoleic
acid, followed by the untreated and vacuum-oven-dried samples. The antiradical activity
of candlenut oil corresponded to an IC50 value of 30.37 mg/mL.
Crude Candlenut OilEthanolysis to Produce Renewable Energy atAmbient Condition

operation variables employed for transesterification were ethanol to oil molar ratio and
catalyst concentration. The objective of the present investigation was to produce a
renewable energy that the ethyl ester formed was used as biodiesel. Pretreatment
process was undertaken to reduce the free fatty acid to less than 2% by esterification
with ethanol. The optimal triglyceride conversion was attained by using ethanol to oil
ratio of 7.5:1, potassium hydroxide as catalyst was of 1.50%. Ethyl ester formed was
characterized by its density, viscosity, cloud and pour points. The ethyl ester viscosity of
5.593 cSt was close to the viscosity of diesel oil of 5.8 cSt, and other properties have
also similar to those of diesel oil.
Solid Liquid Extraction of Jatropha Seeds by Microwave Pretreatment and Ultrasound
Assisted Methods
(Sayyar, S., et. al., 28 May 2011)
Jatropha curcas has a variety of uses which are of great economic significance.
Jatropha oil can be used as fuel alternative and for making biodiesel that is supposed to
overcome the source limitation problem. In this study, conventional, ultrasound assisted
and microwave pretreatment solid liquid extraction of Jatropha seed were studied in
terms of amount and quality of the extracted oil. The free fatty acid content which is animportant oil quality index was also investigated for the obtained oil. Both ultrasonication
and microwave pretreatment of the seeds had a positive effect on amount of yield.
However, by application of ultrasound, more oil could be extracted compared with that
obtained by conventional and microwave pretreatment extraction methods. The
maximum amount of oil which could be extracted by conventional, ultrasound assisted
and microwave pretreatment methods were 47.33, 51.4 and 49.36%, respectively.
Regarding the quality, oil extracted by conventional, ultrasound assisted and
micmicrowave pretreatment extraction methods did not show any significant difference
in terms of Free Fatty Acids (FFA) content.
