PROCESS FOR PRODUCTION OF N,N-DISUBSTITUTED AROMATIC AMINS SUBSTITUTED BY NITROZAMIN-FREE NITRO-GROUPS AND PROCESS FOR STABILIZATION AGAINST FORMATION OF NITROZAMIN

摘要

Processes for the preparation of nitrosamine-free N,N-disubstituted nitroaromatic amines by degradation of their nitrosamine components formed during their preparation, and by stabilization of the products against renewed formation of nitrosamines, by treating the amines in liquid or molten form with a sulfonic acid, where necessary in the presence of inert organic solvents or diluents.
