以苯基磷酰二氯(DCPPO)和烯丙基氯为原料,制备了环氧树脂中间体二烯丙基苯基膦(DAPPO)。通过FT-IR和1H-NMR对反应产物结构进行了表征,同时还测定了产物的熔点及磷含量。探讨了反应的原料比、温度、时间对该反应的影响。获得了最佳反应条件:DCPPO与烯丙基氯格氏试剂物质的量之比为1∶2.2,反应温度为25℃,反应时间为12h,收率53%。 Epoxy resin intermediate diallylphenylphosphine (DAPPO) was prepared from phenylphosphoryl dichloride (DCPPO) and allyl chloride. The structure of the reaction product was characterized by FT-IR and 1H-NMR. The melting point and phosphorus content of the product were also determined. The effects of reaction ratio, temperature and time on the reaction were discussed. The optimum reaction conditions were obtained: the ratio of DCPPO to allyl chloride reagent was 1: 2.2, the reaction temperature was 25 ℃, the reaction time was 12h and the yield was 53%.
