Xylenesulfonate
Hydrotropes are chemicals which in aqueous solutions have the property of "salting i n " or increasing the solubility of a wide variety of slightly soluble organic chemicals. Naxonate· (sodium xylenesulfonate) has outstanding hydrotropic properties.
Naxonate
Suggested Uses
G
A white powder containing a minimum of 9 5 % sodium xylenesulfonate consisting pri marily of sodium sulfonate derivatives of t h e 1,3 isomer with small amounts of the 1,2 isomer. Naxonate G readily dissolves in water to give a clear, straw-colored, slightly a c i d i c s o l u t i o n c o n t a i n i n g a negligible amount (less than 0.1%) of water insolubles.
Naxonate is useful for extracting pentosans and lignin from wood pulp for the produc tion of cellulose with a minimum of degra dation, it is also useful in the processing of bagasse, straw, ramie anil other natural fibers.
A 4 0 % aqueous, clear, straw-colored solu tion of Naxonate G with a specific gravity of 1.158-1.172 and a pH of 7.5-8.5 at 25° C.
Naxonate also is suitable for many other diversified uses, for example, as a pene trating 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 spot ting compounds.
• Effective November 1, 1947, Wyandotte Chemicals Corporation established a new price schedule which for large l.c.l. shipments repre sents 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 here tofore considered uneconomical. · Naxonate
4L and Naxonate G are available in commercial quantities. · The benzene, toluene and p-cymene 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.
