Epichlorohydrin is produced from acetone by (1) chlorinating acetone to form monochloroacetone; (2) disproportionating the monochloroacetone in the presence of a platinum catalyst, a strong acid and preferably a chloride source (for example, added as a salt or from hydrolysis of monochloroacetone) and some water to produce acetone and 1,3-dichloroacetone; (3) hydrogenating the 1,3-dichloroacetone in the presence of a catalyst to produce 1,3-dichlorohydrin; and (4) cyclizing the 1,3-dichlorohydrin with a base to produce epichlorohydrin.

A series of esters of cholesterol with the cis,trans isomers of unsaturated monocarboxylic acids were synthesized.The effect of the nature and of the configuration of the substituents in relation to the double bond in the acid component of the cholesterol esters on the mesogenic capacity was established.The phase transition temperatures were determined.
