摘　　要：以六氟丙烯(HFP)为原料,分子氧为氧化剂,于固定床反应装置上研究了六氟环氧丙烷(HFPO)合成反应.在浸渍法制备的质量分数为10%的Ag/γ-Al2O3催化剂上获得六氟环氧丙烷42%的选择性,考查了第一主族金属盐对催化剂进行改性后的结果,使HFP转化率和HFPO选择性均得到提高,并对催化剂失活原因进行了检测和分析.The synthesis of hexafluoropropylene＇ oxide which uses HFP as raw materials and molecular oxygen as oxidant is studied in packed bed reactor. The selectivity of HFPO in the mass fraction 10% Ag/γ-Al2O3 catalyst prepared by impregnation is 42%. We examined the effect of the 10% Ag/γ-Al2O3 catalyst modified by the first main group metal salts on the synthesis reaction,and both the conversion of HFP and HFPO selectivity were improved, and the reasons for catalyst deactivation was analyzed.
