Process for the preparation of ethercarboxylic acids

摘要

A process for the preparation of carboxylic acids which contain ether groups by the catalytically accelerated addition of alcoholic hydroxyl groups from mono- or polyhydric alcohols to tertiary-alkyl esters of alpha , beta -unsaturated carboxylic acids, and followed with acid hydrolysis of the tertiary-alkyl beta -ethercarboxylate obtained as intermediates in this way.
