摘　　要：以锌粉、烯丙基溴和邻苯二甲酸酐为原料,采用微波辐射技术,在无催化剂条件下直接合成二烯丙基內酯,考察了微波辐射功率和辐射时间对产率的影响,最适宜的反应条件为:锌粉∶烯丙基溴∶邻苯二甲酸酐(摩尔比)=1∶1∶0.4,微波辐射功率225 W,辐射时间5 m in,产率达75%。Using zinc dust, allyl bromide and phthalic anhydride as raw materials, diallyllactone was obtained without catalyst under microwave irradiation. The effect of power and time of microwave irradiation on yield were studied. The most suitable reaction conditions were that the mole ratio of zinc dust, allyl bromide and phthalic anhydride is 1：1：0.4 and the microwave irradiation time is 5 min with the power of 225 W. The yield of diaUyllactone is over 75%.
