A novel reactive distillation approach for producing 1,3-dihydroxyacetone from glycerol

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Glycerol is a viable renewable feedstock that has emerged as a consequence of triglyceride conversion to biodiesel. In addition to glycerol conversion to commodity chemicals, the formation of higher-value specialty chemical products, e.g., 1,3-dihydroxyacetone (DHA) will provide income for the biorefinery. A novel chemical process to convert glycerol to DHA is put forward, which improves efficiency and reduces cost. The essential feature of this process is the selective formation of a 6-membered acetal of glycerol via reactive distillation, followed by selective oxidation of the secondary alcohol to its corresponding ketone product using ruthenium metal and a chemical oxidant. The ketone product is then hydrolyzed to obtain DHA. A continuous process of making DHA from glycerol has been designed. Reactions involved in the process are rapid and can be carried out under mild conditions. Yields of individual process steps are all in excess of 90%, indicating that the process has good potential to reduce DHA production costs. This is an abstract of a paper presented at the 2011 AIChE Annual Meeting (Minneapolis, MN 10/16-21/2011).
