摘要：
A method for producing a polyfluoropropionyl halide, which is characterized by oxidizing at least one dichloropentafluoropropane selected from 3,3-dichloro-1,1,1,2,2-pentafluoropropane and 1,3-dichloro-1,1,2,2,3-pentafluoropropane by oxygen under irradiation with light and in the presence of chlorine.The polyfluoropropionyl halide can be obtained from the dichloropentafluoropropane industrially advantageously in good yield. Further, in a gas phase reaction, the polyfluoropropionyl halide can be obtained in a very high reaction yield without decomposition of the desired product and without corrosion of the material for the reactor or the glass for the light source portion even in a reaction for a long period of time.
