PURPOSE:To obtain a new compound, pentafluoroethyl 2,2,2-trifluoroethyl ether, not decomposing the ozonosphere, and capable of being used for cooling media or foaming agents as the substitute of CFC. CONSTITUTION:This new compound is produced by reacting a fluorine-containing carbonyl compound of the general formula CF3COR1 (I) (R1 is fluorine, chlorine, bromine or iodine) with a compound of the general formula R2-CH2CF3 (II) (R2 is sulfate group) in the presence of an alkali metal fluoride or alkaline earth metal fluoride in an aprotic polar solvent. |
