The opportunity of application of dimethylamine in pure form and also in forms of water solutions of free or hydrochloric amine for synthesis of dimethylaminopropionitrile by cyanoethylation is investigated. A stages of nitrile isolation with use of salting-out and one purification by vacuum distillation is developed. It is established that the problem of producing of acceptable pure nitrile may be solved only by use of pure dimethylamine. Method of synthesis and purification of dihydroxyethylaminopropionitrile is developed.
