Abstract: The catalytic behavior of self-made phosphomolybdic acid for esterification reaction under microwave irradiation was studied，and effects of catalyst amount，microwave power and irradiation time were investigated. Under the optimal conditions，i.e.，phosphomolybdic acid amount of 0.05 g，microwave power of 640 W and irradiation time of 40 min，n-butyl acetate yield could be achieved to 94.5%.

摘要： 以自制的磷钼酸为催化剂，研究了微波辐射条件下磷钼酸对酯化反应的催化性能。探讨了催化剂用量、微波辐射功率、微波辐射时间对反应的影响。在优化反应条件下，即磷钼酸0.05 g、微波功率640 W、辐射时间40 min时，酯的收率达到94.5%。
