| Abstract: | N,N-dimethylpropanamide (DMAA) is a raw material of fine chemical industry, which has a bright developing and using future. Nowadays the DMAA is used in many fields, such as in petroleum recovery, modification of fiber and plastics, fine chemical industry, science of life, etc.. In a microchannel reactor, the DMAA was synthesized with 3-(dimethylamino)-N,N-dimethyl-propanamide (DMDA) as raw material and tetrabutyl ammonium bromide (TBAB) as catalyst. The effects of catalyst dosage, current capacity and reac... |
