【Abstract】 Contraposing some technical problems on traditional heating synthesis technique of the quinclorac allyl ester(QAE), such as time -consuming, low yield etc, the microwave irradiation synthesis technique of the QAE was researched and established. The optimum synthesis conditions were obtained. And the ester was analyzed and characterized by the IR spectrum, the NMR spectrum and melting point measurement. All results showed that the production was QAE and purity of it was high. Contrasting yields of the microwave irradiation synthesis process with that of the traditional heating, so many advantages were represented on many different aspects such as reaction time, the reaction productive rate, the amount of catalyst, and the purity of production.更多还原
