Abstract

An epoxy ester of an organic carboxylic acid is prepared by mixing an organic carboxylic acid with an epoxy halo-substituted compound in which the halogen atom is attached to a carbon atom adjacent to the epoxy group and adding an inorganic alkaline compound thereto. Suitable acids are the soap-forming acids such as fatty acids of 12 to 20 carbon atoms per molecule and dimers and trimers of unsaturated fatty acids or mixtures thereof. Other, aliphatic, cycloaliphatic, aromatic or heterocyclic mono or dicarboxylic acids may be used. The acids may contain alkoxy or ester radicals. Preferred epoxy halo-substituted compounds are of the formula <FORM:0876125/IV (b)/1> in which R is hydrogen or a hydrocarbon radical, preferably an aliphatic radical of not more than 10 carbon atoms. The alkaline compound may be potassium, sodium, lithium, calcium or magnesium hydroxide, as well as magnesium oxide or calcium oxide. As catalyst there may be used a tertiaryamine, those amines having a pH of less than 10 in aqueous solution being preferred. Quaternary salts of the formula [Y.R4]+X-in which Y is nitrogen, phosphorus or arsenic, X is an anion of an inorganic acid, and R is a hydrocarbon radical, may also be used. The catalyst may be used in amounts varying from 0.01% to 5% by weight of the carboxylic acid. The reaction may take place at a temperature of 95 DEG C. to 117 DEG C., preferably at 110 DEG C. The alkaline compound is preferably added over a period varying from 35-145 minutes. Specification 763,559 is referred to.
