ABSTRACT:
There is provided an improvement in the process for the amination of bis(2-chloro-1-nitrosocyclohexane) wherein bis(2-chloro-1-nitrosocyclohexane) prepared by reacting cyclohexene with nitrosyl chloride in the presence of liquid sulfur dioxide is treated with ammonia. Sulfur dioxide contained in the nitrosation reaction mixture in the form of a slurry or solution containing bis(2-chloro-1-nitrosocyclohexane) is evaporated in the presence of an inert organic solvent, incorporated into the reaction mixture, and is substantially removed from the reaction mixture. Thereafter, the slurry or solution of bis(2-chloro-1-nitrosocyclohexane) in the inert organic solvent thus prepared is treated with ammonia.
