将含有全氟丙烯的全氟环氧丙烷以一定的速度通入保持在-15℃的二乙二醇二甲醚、氟化钾、α-氟磺酰基全氟乙酰氟混合物中,反应得到化合物(1a)、(1b)、(1c)。在反应过程中,通入的全氟丙烯除少量溶于反应混合物外,其余大部分不参加反应,並且能够回收。同时还发现,当反应温度超过0℃,全氟丙烯与1反应,得到全氟酮2。 Perfluoropropene containing perfluoropropene was passed at a rate through a mixture of diethylene glycol dimethyl ether, potassium fluoride, and α-fluorosulfonyl perfluoroacetyl fluoride maintained at -15 ° C to obtain a compound (1a), (1b), (1c). During the reaction, a small amount of the perfluoropropene introduced was dissolved in the reaction mixture, and most of the other did not participate in the reaction and was able to be recovered. It was also found that when the reaction temperature exceeds 0 ° C, perfluoropropene reacts with 1 to yield perfluoroketone 2.
