Process for elimination N-nitrosamines from N-nitrosamine-containing compositions

摘要

A process for eliminating N-nitrosamines, particularly N,N-dialkyl-N-nitrosamines and N-alkyl-N-aryl-N-nitrosamines from N-nitrosamine containing compositions through the addition of organic carboxylic acid halides. The process eliminates N-nitroso compounds without rearrangement to C-nitroso compounds.
