Abstract
16,260. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. July 12. Glycerine, purifying; fatty acids, purifying; fatty acids and glycerine, obtaining by decomposing fats and fatty oils. - Glycerine is decolorized by hydrosulphites or formaldehyde sulphoxylates. The glycerine may be in solution, and the insoluble decolorizing-salts, such as decroline (basic zinc formaldehyde sulphoxylate), are preferred. The glycerine may be preliminarily purified by a salt of iron or aluminium. These reagents may be added during the saponification of fats and oils, as by means of zinc dust, zinc oxide, or magnesium oxide; the fatty acid and glycerine thus obtained are both decolorized.
