Abstract
A lower alkyl trichloroacetate and a vicinal alkylene diol react when heated together in the presence of a weak base to produce chloroform, a lower alkanol, and the cyclic alkylene carbonate. The chloroform and lower alkanol distill from the reaction mixture substantially as formed and the alkylene carbonate is readily separable from the residual mixture.
