Abstract
The invention relates to a process for continuously preparing alkylamino(meth)acrylamide by reacting methyl (meth)acrylate, ethyl (meth)acrylate or amines having a high boiling point compared to methanol or ethanol. A special workup technique which includes removing water from the amine before entering the reactor allows product qualities which have hitherto not been attained to be achieved. In addition, very high space-time and overall yields can be achieved.
