ABSTRACT:
A process for preparing precursors for amido containing organic peracids is disclosed wherein a diester of a dibasic acid is reacted with an amine to provide a mono amido carboxylic acid ester. The reaction is conducted in a reaction column to provide a highly selective reaction which limits the amount of diamide produced. The selective reaction is conducted with a moderate excess of diester and may be conveniently operated on a continuous basis.
