    NAXONATE Sodium Xylenesulfonate

    Hydrotropes are chemicals which in aqueous solutions have the property of "salting in" or increasing the solubility of a wide variety of slightly soluble organic chemicals. Naxonate (sodium xylenesulfonate) has outstanding hydrotropic properties.

    Naxonate G A white powder containing a minimum of 9 5 % sodium xylenesulfonate consisting primarily of sodium sulfonate derivatives of the 1,3 isomer with small amounts of the 1,2 isomer. Naxonate G readily dissolves in water to give a clear, straw-colored, slightly acidic so lut ion containing a negligible amount (less than 0.1%) of water insolubles.

    Naxonate 4L A 40% aqueous, clear, straw-colored solution of Naxonate G with a specific gravity of 1.158-1.172 and a pH of 7.5-8.5 at 25 C.

    Suggested Uses Naxonate is useful for extracting pentosans and lignin from wood pulp for the production of cellulose with a minimum of degradation, i t is also useful in the processing of bagasse, straw, ramie anil other natural fibers.

    Naxonate also is suitable for many other diversified uses, for example, as a penetrating agent in rewetting and processing hides in the tanning industry; to assist in the removal of hard-water scale in aqueous systems and as a component of textile spotting compounds.

    Effective November 1, 1947, Wyandotte Chemicals Corporation established a new price schedule which for large l.c.l. shipments represents a price reduction of over 30% for Naxonate 4L and over 10% for Naxonate G. This lower cost may open up many uses for Naxonate heretofore considered uneconomical. Naxonate

    4L and Naxonate G are available in commercial quantities. The benzene, toluene and p-cy-mene homologues of sodium xylenesulfonate likewise exhibit hydrotropic properties and are being offered in experimental quantities for your evaluation. For samples and additional data, write to the Development Department.
