ABSTRACT:
A process for preparing precursors for amide containing organic peracids is disclosed wherein a polycarboxylic acid is esterified with a low molecular weight alkyl alcohol followed by formation of an amide by reacting the ester with an amine to provide a monoamido carboxylic acid ester. Unwanted diester is removed from the reaction mixture by precipitation at relatively low temperature. The ester is recovered from the reaction mixture by either precipitation or a distillation procedure under high temperature and reduced pressure. The esters are converted to acids highly desirable as precursors for peracids useful as bleaches in laundry detergents.
