p-Divinylbenzene → 2-(4-Ethenylphenyl)oxirane

참여 물질

반응 단계

In a one-liter reactor equipped with a stirrer and a thermometer were placed 25 g of p-divinylbenzene, 40 g of sodium hydrogencarbonate and 400 ml of toluene. Thereto was dropwise added 100 g of a toluene solution containing 40% by weight of m-chloroperbenzoic acid at 5° C. with stirring. Stirring was continued for further 10 hours at 5° C. After completion of the reaction, the reaction mixture was washed with an aqueous sodium hydrogencarbonate solution and dried with anhydrous magnesium sulfate. The drying agent was removed by filtration and the filtrate was subjected to vacuum distillation to remove toluene. The residue was purified by distillation to obtain 65 g of 4-vinylstyrene oxide (1 Torr, 74° C.).
