Abstract:: The synthesis of hexafluoropropylene oxide which uses HFP as raw materials and molecular oxygenas oxidant is studied in packed bed reactor. The selectivity of HFP0 in the mass fraction 10% Ag/y-Al,0, cat-alyst prepared by impregnation is 42% . We examined the effect of the 10% Ag/y-Al, 0, catalyst modified bythe first main group metal salts on the synthesis reaction , and both the conversion of HFP and HFPO selectivitywere improved ，and the reasons for catalyst deactivation was analyzed.
