METHOD OF PRODUCTION OF 3-DIMETHYLAMINOPROPYLAMINE AT LOW PRESSURE Russian patent published in 2008 - IPC C07C209/48 

Abstract RU 2326108 C2

FIELD: chemistry.

SUBSTANCE: invention pertains to the method of obtaining 3-dimethylaminopropylamine, used as an intermediate product in organic synthesis. Description is given of the method of obtaining the 3-dimethylaminopropylamine with high purity degree from N,N-dimethylaminopropyonitrile with use of hydrogenation method at low pressure. The method involves contacting nitrile with hydrogen at low pressure in the presence of a catalyst, under conditions allowing for turning the nitrile into 3-dimethylaminopropylamine with high output and purity of over 99%.

EFFECT: high output.
