METHOD OF OBTAINING N,N-SUBSTITUTED 3-AMINOPROPAN-1-OLS Russian patent published in 2014 - IPC C07C213/00 C07C215/08 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of obtaining N,N-substituted 3-aminopropan-1-ols by: a) interaction of the secondary aliphatic amine with acrolein at a temperature from -50 to 100°C and pressure from 0.01 to 300 bars and b) interaction of the obtained at the stage a) reaction mixture with hydrogen and ammonia in the presence of a hydration catalyst under pressure from 1 to 400 bars. The molar ratio of the secondary aliphatic amine to acrolein at the stage a) constitutes 1:1 to 8:1, a temperature at the stage b) is in the interval from 20 to 40°C and the molar ratio of ammonia used at the stage b) to acrolein used at the stage a) constitutes from 1:1 to 10:1.

EFFECT: method makes it possible to obtain the target product with high selectivity.
