Abstract
Nitrosamines are prepared by reacting a dialkylamine, diarylamine or alkylarylamine with a mixture of nitrogen dioxide and nitric oxide at a temperature between 10 DEG C. and 300 DEG C. The reaction may be conducted in a liquid or vapour phase and preferably in the presence of up to two moles. of diluent per mole. of amine. Specified diluents are nitrogen, carbon dioxide and steam. The examples describe the preparation of N-nitroso-N-ethylaniline; dimethyl-, diethyl, di-n-butyl- and diphenylnitrosamines.
