METHOD OF OBTAINING N-NITROSODIALKYLAMINES Russian patent published in 2014 - IPC C07C243/06 C07B43/02 

Abstract RU 2506255 C1

FIELD: chemistry.

SUBSTANCE: relates to field of obtaining N-nitrosodialkylamines. Method of obtaining N-nitrosodialkylamines consists in interaction of water solutions of dialkylamines with carbon dioxide with molar ratio of dialkylamine to carbon dioxide (1÷2):1 with further processing of carnonates of dialkylamines with gas mixture of nitrogen with equimolecular mixture of nitrogen oxide and dioxide or gas mixture of nitrogen with nitrous anhydrite with molar ratio of dialkylamine to nitrogen oxides, in terms of nitrous anhydrite, not less than 1:1, reaction mass being kept at temperature 30-60°C, with support of pH of reaction mixtures 3-6.5 for 15-60 minutes.

EFFECT: invention makes it possible to reduce energy consumption, ensure ecological safety of technological production, with simultaneous increase of end product.
