摘　　要：报道了以杂多酸为催化剂合成甲基丙烯酸丁酯的研究结果 ,探讨了催化剂的用量、反应时间、反应温度、醇酸物质的量比等因素对反应结果的影响 ,确定了反应的最佳条件 ,讨论了催化剂的催化活性和使用寿命 .合成产品用气相色谱监测 ,并用IR和HThe study to synthesize methacrylic butanol ester with heteropoly acid as catalyst has been reported. The effects of catalyst, reaction time, reaction temperature and the ratio of the reactants were examined. The best experimental condition to react was determined. The catalytic vitality and repeatability of the catalyst was discussed. The synthesized product was supervised with gas chromatography and confirmed with IR and H-NMR.
