摘要： A reactive-separation process converts glycerin into lower alcohols, having boiling points less than 200 °C, at high yields. Conversion of natural glycerin to propylene glycol through an acetol intermediate is achieved at temperatures from 150° to 250 °C at a pressure ranging from 1 and 25 bar. The preferred applications of the propylene glycol are as an antifreeze, deicing compound, or anti-icing compound. The preferred catalyst for this process in a copper-chromium powder.

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.-

摘要： A process for converting glycerol to propylene glycol with high selectivity, comprising the steps of:
heating a glycerol-containing feedstock material in presence of a catalyst that is capable of dehydrating glycerol at a temperature from 170°C to 270°C and a pressure from 0.2 to 25 atmospheres with hydrogen as a limiting reagent to prevent formation of propylene glycol such that there is resultant formation of acetol in the feedstock material;
liberating the acetol in vapor phase from the feedstock material; and
reacting the acetol in vapor phase with hydrogen in the presence of a catalyst that is capable of hydrogenating acetol at a hydrogen partial pressure ranging from 0.2 to 50 bars to form propylene glycol.摘要翻译： 一种以高选择性将丙酮醇转化为丙二醇的方法，包括以下步骤：将含有少于80％（重量）水的含丙醛醇的原料与能够使丙酮醇氢化形成反应混合物的催化剂组合; 并在0.2至25巴的压力下将反应混合物加热至50-250℃的温度。
