Abstract

17,726. Kochnitzky, M., and Friedl, A. Aug. 3. India-rubber, extracting resins from. - Raw rubber is de-resinated by treatment with compounds obtained by mixing equivalent proportions of aromatic bases, such as pyridin or aniline with phenol or cresol, that is, one molecule of phenol or cresol with one molecule of pyridin or aniline. The mixture is preferably heated to about 95‹ C., and the solution of resin is then run off. The remaining rubber is washed with fresh quantities of solvent, and may be then treated with dilute caustic soda, water, and steam.
