METHOD OF PRODUCING AMINES FROM GLYCERINE Russian patent published in 2013 - IPC C07C209/16 C07C211/13 C07D241/04 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing amines and/or alkanolamines mainly containing mono- and diamine alkanols, alkyldiamines and triamines and cyclic amines by reacting glycerine with hydrogen and an aminating agent selected from the group: ammonia, methylamine and diethylamine, in the presence of a catalyst which contains a metal selected from Cu, Co, Ni, Mn, Mo, Cr, Zr, or a mixture thereof, at temperature ranging from 150°C to 300°C and pressure ranging from 20 to 300 bar, followed by separation of the end product. The process is carried out until 40-80% conversion of glycerine. The invention also relates to a method of producing amines and/or alkanolamines mainly containing mono- and diamine alkanols, alkyldiamines by reacting glycerine with hydrogen and aminating agent selected from ammonia, methylamine and diethylamine, in the presence of a catalyst which contains iridium, at temperature ranging from 150°C to 300°C and pressure ranging from 20 to 300 bar.

EFFECT: method enables efficient and full utilisation of glycerine as a starting material and obtain products with high output.
