摘　　要：以丙烯酸和正丁醇的酯化反应为例 ,系统地研究了杂多酸及其盐的催化性能 ,并对影响催化性能的因素进行了系统的考察。实验结果表明 ,H3PW12 O40 ·nH2 O(简写为PW12 ,其它类同 ) ,PMo12 ,SiW12 ,BW12 具有较高的催化活性。Taking the esterification reaction of acrylic acid and butanol as examples, the catalytic activity of heteropolyacids and their salts has been systematically studied. Several factors affecting the catalytic activity are discussed. Experimental results show that PW 12 ,SiW 12 ,MoW 12 and BW 12 have higher catalytic activities.
