IMPROVED PROCESS FOR THE PRODUCTION OF N, N-DIMETHYL-ALKYLAMINES BY CATALYTIC HYDROGENATION OF N, N-DIMETHYL-ALKYLAMIDES

摘要

N, N-dimethylalkylamines containing less than 1% of alkanols are obtained by hydrogenation under 10 to 100 bar, and at 220-280 degree (s) C of N, N-dimethylalkylamides, on a chromite type catalyst. copper containing from 2 to 10% of manganese oxide. The process is particularly applicable to the production of N, N-dimethyl (coconut) amines (fatty chain at about 12-14 carbons) . / P
