Process for producing acetol from glycerol

摘要

A process for converting acetol to propylene glycol with high selectivity, comprising the steps of:
combining an acetol-containing feedstock with less than 80% by weight water with a catalyst that is capable of hydrogenating acetol to form a reaction mixture; and
heating the reaction mixture to a temperature ranging from 50° to 250°C at a pressure ranging from 0.2 to 25 bar.
