Process for the preparation of isocyanate derivatives of aliphatic, cycloaliphatic, and araliphatic compounds

A process comprising reacting an aliphatic, cycloaliphatic, or araliphatic compound containing from 1 to 3 N-chloramide groups bound to from 1 to 3 secondary or tertiary carbon atoms which are part of (1) an aliphatic radical which contains from 3 to 30 carbon atoms, (2) a cycloaliphatic radical which contains from 4 to 18 carbon atoms, or (3) an araliphatic radical having from 6 to 18 carbon atoms in its aromatic portion and from 3 to 30 carbon atoms in its aliphatic portion, or a combination of said compounds, with at least one mole of a tertiary amine having a pk.sub.a greater than 7 per equivalent of N-chloro amide, at a temperature from about 20.degree. to about 180.degree. C., in an inert solvent, to convert the N-chloro amide groups into isocyanate groups.
