PROCESS FOR PREPARING METAL-FREE FATTY PEROXYACID PRECURSORS HAVING AMIDE MOIETIES IN THE FATTY CHAIN

摘要

PROCESS FOR PREPARING METAL-FREE FATTY PERACID PRECURSORS HAVING AMIDE MOITETIES IN THE FATTY CHAIN A process for preparing metal-free precursors for amide containing organic peracids is disclosed wherein a polycarboxylic acid is esterfied 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. The ester is recovered from the reaction mixture by a distillation procedure under high temperature and reduced pressure. The esters are converted to acids highly desireable as precursers for peracids useful as bleaches in laundry detergents.
