- Description
- Conversion of glycerol to allyl alcohol which is converted to glycidol in a separate process step is discussed in this paper. Microreactor studies were carried out over a number of catalysts and operating conditions with the aim of improving the overall process yield to glycidol. To increase the reaction selectivity of the first step (glycerol to allyl alcohol), the support was modified with alkaline metal salts. It was found that the catalyst treatment with solutions of sodium, potassium, caesium and rubidium significantly enhanced the allyl alcohol yield using a 35%wt. glycerol aqueous feed. Furthermore the addition of organic reductants increased the yield of conversion of glycerol to allyll alcohol. Optimisation towards high allyl alcohol selectivity was achieved by variation of alkaline metal cation modifiers and addition of reducants. A model for the influence of acid, base and redox properties on slecctivity and yield is presented.
