摘　　要：丙酸及丙酸乙酯是重要的化工产品和有机合成中间体。中国乙醇资源丰富,以乙醇为原料的非石油途径合成丙酸及丙酸乙酯得到了广泛研究。乙醇均相羰基化存在收率低、反应条件苛刻以及产物与催化剂分离困难等问题。目前,多数研究主要集中在乙醇羰基化多相催化剂的开发。乙醇羰基化多相催化剂分为两类:贵金属催化剂和非贵金属催化剂。该文详细介绍了两类催化剂的研究进展,重点阐述了两类催化剂的反应机理以及助剂、载体和工艺参数对催化剂性能的影响,指出了不同催化剂的优势和不足,并对催化剂应用现状进行了分析。最后展望了乙醇多相羰基化合成丙酸及丙酸乙酯的发展前景。Propionic acid and ethyl propionate are important chemical products and intermediates in organic synthesis.And non-petroleum synthesis of propionate and ethyl propionate from ethanol has been extensively studied due to the abundance of ethanol resources in China.However,homogeneous carbonylation of ethanol displayed problems of low yield,harsh reaction conditions and difficulty in separating the product from the catalyst.Therefore,the current research on ethanol carbonylation mainly focuses on heterogeneous catalysts,includes noble and non-noble metals.Herein,the research progress of these two types of catalysts was introduced in detail,especially the reaction mechanism of the two types of catalysts as well as the effects of promoters,supports and process parameters on the catalysts’activities.The advantages,disadvantages and the application status of different catalysts were also discussed.Finally,the future development directions of synthesis of propionic acid and ethyl propionate by heterogeneous ethanol carbonylation was prospected.
