Abstract: CLYCERINE IS PRODUCED BY REACTING ALLYL ACETATE WITH PERACETIC ACID IN THE PRESENCE OF ACETIC ACID AT ELEVATED TEMPERATURE. THE DIACETIN FORMED IS CONVERTED TO GLYCERINE BY ALCOHOLYSIS AFTER REMOVAL OF THE UNREACTED ALLYL ACETATE AND THE ACETIC ACID. HIGHER PERPLIPHATIC ACIDS CAN BE USED IN A SIMILAR MANNER.

Abstract: Olefinically unsaturated organic compounds are epoxidized with solutions of organic percarboxylic acid. An aqueous solution of the percarboxylic acid having at least 2 carbon atoms is dehydrated by extraction and/or distillation with the compound to be epoxidized. The dehydrated product is held at 30* - 100* C. and subjected to a subsequent reaction.
