Abstract

1,051,649. Perfluoro - 2 - oxo - 3,6 - dimethyl - 1,4 - dioxane. E. I. DU PONT DE NEMOURS & CO. Oct. 14, 1964, No. 25544/66. Divided out of 1,051,647. Heading C2C. The invention comprises the compound and its production by reacting CF 3 COCOF or its dimer (see Specification 1,051,647) with hexafluoropropylene oxide in a polar organic solvent in the presence of an alkali metal fluoride at a temperature below 100‹ C. The above compound reacts with SF 4 to give
