摘要

综述了醋酸（甲酯）与甲醛羟醛缩合生成丙烯酸（甲酯）路线所用的催化剂，主要包括V-P-O、碱金属/碱土金属型、离子液体类型催化剂的结构特性、催化性能等方面的最新研究进展，认为开发新型催化剂是该工艺路线的核心技术。

Abstract

This paper supplies an overview of latest progress in structural features and catalytic performance of the catalysts for aldol condensation reaction between acetic acid (methyl acetate) and formaldehyde to synthesize acrylic acid (methyl acylate),mainly including V-P-O,alkali metal/alkaline earth metals and ionic liquids catalysts.It is pointed out that the development of new type catalysts is the core technology for the synthesis of acrylic acid (methyl acylate) via aldol condensation route.
