production method | 1. preparation method: add 98g(0.6mol) of methyl p-ethylbenzoate, 1g of chromium oxide and 4g of calcium carbonate into a mortar, grind them into fine powder, transfer them into a reaction bottle equipped with a stirrer, thermometer and ventilation duct, pass air, and heat the reaction bottle. Heat to 140~150 ℃ under vigorous stirring and react for 24 hours. The generated water is continuously steamed and collected throughout the process. After the reaction, add 100mL of benzene, filter, and wash the filter cake with benzene. Decompression distillation, recovery of unreacted raw material (2)29~32g(118~121 ℃/2.13kpa), and then collection of 149~150 ℃/0.93kpa fraction, compound (1)43~45g, the conversion rate of 40% ~ 42%, the yield is 60%. Recrystallization with benzene-hexane (1:1) to obtain white solid, mp92 ~ 94 ℃, recovery rate 82% ~ 85%. [1] |
