| Abstract: | The benzoin condensation reaction was studied by using vitamin B1 as catalyst and PEG-6000 as phase transfer catalyst under microwave heating.The method of added reagent was actualized under room temperature.The influences of the sequence of added reagent,the amount of VB1,microwave power,micro- wave time,pH,the amount of PEG-6000 on the yield of benzoin condensation reaction were investigated. The yield of benzoin was 70.9% under the optimum reaction condition. |
