A process for the production of HFPO includes introducing a feedstock comprising HFP and molecular oxygen into a heated reaction zone of a reactor. The reaction zone is at a reaction temperature Tr, where 180° C.≦Tr≦230° C. The feedstock is allowed to react, by epoxidation of the HFP, to produce HFPO. The HFPO is withdrawn from the reaction zone. The introduction of the feedstock into the reaction zone and the withdrawal of the product from the reaction zone is continuous.
