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.
L'invention porte sur un procédé de production continue d'alkylamino (méth)acrylamides par réaction de (méth)acrylates d'alkyle avec des amines à haut point d'ébullition. Par une activation catalytique et une technique particulière de traitement, on attend des qualités du produit non encore réalisées à ce jour. Il est en outre possible d'arriver à des valeurs très élevées du rendement espace-temps et du rendement global.
