Abstract
Hexachloroacetone and a vicinal alkylene diol react when heated together in the presence of a weak base to produce chloroform and the cyclic alkylene carbonate. The chloroform distills from the reaction mixture substantially as it is formed and the alkylene carbonate is readily separable from the residual mixture.
