乳酸(酯)脱水制备丙烯酸(酯)研究进展

Preparation of acrylates by direct dehydration of lactic acid or lactates

从植物淀粉发酵制备乳酸已经获得工业化生产,开发经济可行的生物质路线制备丙烯酸是生物资源利用的重要研究方向之一。因此,对近年来用乳酸脱水制备丙烯酸的研究工作进行了综述、分析和归纳,对应用前途可能性较大的几种新型的催化材料和方法进行了探索和讨论。

Lactic acid is commercially produced by glucose fermentation derived from plant starch. Conversion of lactic acid to acrylic acid is an attractive target for new biobased alternatives to chemicals currently produced from petroleum. This paper reviewed the research attempts in recent years to develop the dehydration technologies for the conversion of the lactic acid and its esters into the acrylic acid or acrylates. Special attentions and discussions were focused on those novel cost-effective catalytic technologies and catalysts for the manufacture process of the acrylic acid and acrylates.
