| 摘 要： | 对六氟丙烯在空气中直接环氧化合成六氟环氧丙烷进行了动力学研究。以载Ag／γ-Al2O3为催化剂，经实验研究证实，在所制备的催化剂上，当原料气总流速大于150mL／h，催化剂粒径小于币2．5min时，内、外扩散对反应均无影响。

| Abstract: | The kinetics studies have been done for direct with γ-Al2O3 supported silver catalyst. The results show more than 150 mL/h, and the granule diameter of the gas - phase epoxidation of hexafluoropropylene that when the total flow rate of the reactants is catalyst is smaller than ~ 2.5 mm, there is no effect on the reaction for the internal diffusion and external diffusion. |
