ABSTRACT:
Reacting a diol (1) with a carbonic ester (2) to produce a cyclic carbonic ester (3) using a salt of a weak acid with an alkaline metal or alkaline earth metal as a catalyst. The diol (1) contains diols having an asymmetric carbon atom. The reaction mixture is neutralized and distilled to obtain a cyclic carbonic ester. Cyclic carbonic esters are produced using an easily accessible and easy to handle reactant, with good yield and under mild and moderate conditions. ##STR1##
