| Abstract: | The synthesis of benzoin under the condition of microwave-assisted heating was studied. The influence of microwave heating power, microwave heating time, reaction system temperature, and the catalysis dosage on yield were investigated. The results indicate that the influence of the catalysis dosage, reaction system temperature, microwave heating time and microwave heating power on yield decreased in turn and the optimum reaction conditions were the catalysis dosage lg, reaction system temperature 80 ℃, microwave heating time 20 min and microwave heating power 900 W. The mehing point and infrared spectrum accord with standard sample. |
