中文摘要：
在超临界二氧化碳中和氧气存在的条件下,将PdCl2/高分子聚苯乙烯负载苯酚（PS-Phenol）共催化剂成功地应用于丙烯酸甲酯与甲醇的缩醛化反应中. 当丙烯酸甲酯全部转化时,缩醛化产物 3,3-二甲氧基丙酸甲酯的最佳产率和选择性分别为97.7%和100%. 与小分子酸性助催化剂相比, PS-Phenol可以通过简单的过滤分离而循环再利用,这有利于贵金属钯的分离与回收.
英文摘要：
PdCl2/polystyrene-supported phenol （PS-Phenol） was presented as a co-catalyst for the acetalization of methyl acrylate with methanol in supercritical carbon dioxide under oxygen atmosphere. After methyl acrylate was completely converted, the highest yield and selectivity for methyl 3,3-dimethoxypropanoate were 97.7% and 100%, respectively. Compared with small molecular acidic co-catalysts, the separation of PS-Phenol from the reaction system by simple filtration made the recycling of precious palladium practical and convenient.
