ABSTRACT:
Colorless low-viscosity diglycidyl esters of cycloaliphatic dicarboxylic acids of low molecular weight and with a high epoxide group content are obtained in substantially quantitative yields by reacting the cycloaliphatic dicarboxylic acids with excess epihalohydrin in the presence of 0.5 to 4 % by weight based on the dicarboxylic acid of secondary and/or tertiary O-alkali phosphate as catalyst at 80.degree. to 115.degree.C, followed by dehydrohalogenation of the 3-halogen-2-hydroxy propyl carboxylic acid esters formed with aqueous alkali.
