Abstract

Process for the preparation of etherepolycarboxylic acids, characterized in that ethereocarboxylic acids of the general formula are reacted with carbon dioxide ** (see formula) ** In which R represents an alkyl radical of 1 to 22 carbon atoms, which may be straight or branched chain and be substituted by hydroxyl or carboxyl groups or interrupted by oxygen atoms and R 'represents hydrogen or a lower alkyl radical of 1 to 4 carbon atoms, in the form of its alkali metal salts, at temperatures of 200 to 350ºC and preferably of 250 to 300º c, under pressure, in the presence of alkali metal alcoholates and optionally of heavy metal catalysts, as well as indifferent diluents, and eventually converted in a known manner into the free acid the formed alkaline salt of the etherealcarboxylic acid.
