Abstract

The invention relates to a process for continuously preparing N-alkyl(meth)acrylamides by reacting alkyl(meth)acrylates with high-boiling amines. A catalyst activation and specific workup technique achieve product qualities which have not been achieved to date. In addition, very high space-time yields and overall yields can be achieved.
