Abstract: A selective process wherein toluene diisocyanate distillation residue is converted from a viscous liquid into an inert, granular solid by treatment with an organic acid.This invention relates to the treatment and processing of the distillation residue which is obtained in the production of toluene diisocyanate. More particularly, the invention relates to a process for converting this residue into an inert, non-toxic and easy-to-handle granular solid.Toluene diisocyanate is produced on a large commercial scale by a process which comprises reacting toluene diamine with excess phosgene usually in the presence of an organic solvent medium. An illustrative process is disclosed in U.S. Pat. No. 3,287,387. Along with toluene diisocyanate, the phosgenation product mixture usually comprises unreacted phosgene, solvent, hydrogen chloride by-product, and a relatively substantial proportion of side reaction products in the form of residual and high-boiling materials.

Abstract: Compounds containing an azo-linkage connecting two similar polyol esters constituents are described. These azo di-ester polyols are prepared by the direct esterification of azo diacids with polyols, in the presence of a strong mineral acid catalyst.
