Abstract

The production of glycol monoesters of .alpha.,.beta.-unsaturated carboxylic acids of three or four carbon atoms and 1,2-diols of two to four carbon atoms by the reaction of acids with 1,2-alkylene oxides of two to four carbon atoms at elevated temperature in the presence of catalysts and polymerization initiators and also of molecular oxygen as an additional agent for suppressing polymerization.
