4,4’—二氟二苯甲酮合成工艺研究

Synthesis of 4,4 - Difiuorobenzophenone

采用4,4’-二氨基二苯甲烷为原料,经过重氮化反应、氧化反应合成4,4’-二氟二苯甲酮。通过对工艺路线的改进及反应条件的优化,该工艺制得产品收率为84％,为工业化生产提供了一条经济有效生产方法。

4,4 - difluorobenzophenone was prepared from 4,4' - diamino - diphenylmethane by diazotization in fluoroboric acid solution and oxidation reaction. After the optimum synthetic process conditions, the target product was obtained in 84% yield. An econonmic and effective production synthetic route was introduced and discussed.
