Abstract
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 diallyllactone is over 75%.
