Liquid phase fluorination of diethyleneglycol dimethyl ether, tetraethyleneglycol dimethyl ether, 2<1,2-dichloro-1,2-difluoroethyl> tetrahydrofuran and 2<1,2-dichloro-1,2-difluoroethyl> dioxane 1,4 produce the corresponding perfluoroethers in 56, 43, 67 and 74 percent yields respectively.The by-products are partially fluorinated compounds and no fragmentation is observed.The simplicity of the reactions and method of preparation make this approach to fluorinated fluids and oils industrially attractive.
