Disclosed herein is a method of preparing a perfluoroalkadiene. A dihaloperfluorocarbon used as a starting material is added dropwise to a nonpolar organic solvent, a metal powder and an organic metal compound. The dihaloperfluorocarbon is slowly added dropwise in a temperature range from 30° C. to 150° C. for a certain period of time. Moreover, the nonpolar organic solvent used may be benzene, toluene, xylene, etc., and the organic metal compound is used by being dissolved in ethyl ether or tetrahydrofuran at a concentration of 1 to 3M. The metal powder used may be Mg, Zn, Cd, etc.
本文揭示了一种制备全氟烯的方法。使用二卤代全氟碳化合物作为起始物,滴加到非极性有机溶剂、金属粉末和有机金属化合物中。在30°C至150°C的温度范围内缓慢滴加二卤代全氟碳化合物一段时间。此外,所使用的非极性有机溶剂可以是苯、甲苯、二甲苯等,有机金属化合物以1至3M的浓度在乙醚或四氢呋喃中溶解。所使用的金属粉末可以是镁、锌、镉等。
