实验步骤: A mixture of 228 g of hexafluoropropene epoxide and 72 g of hexafluoropropene, and also 220 g of hydrogen fluoride were filled into a 1 liter capacity stainless steel autoclave without a stirring device and the mixture was heated for 20 hours at 100° C. The reaction product, which consisted of a solution of hexafluoroacetone in hydrogen fluoride, was transferred by exploiting its own vapor pressure to a 2.7 liter capacity nickel autoclave, which already contained 258 g of phenol, and the resulting mixture was heated for 8 hours at 100° C. After the hydrogen fluoride and the hexafluoropropene, which did not take part in the reaction, had been distilled off, 399 g of hexafluoro-2,2-bis-(4-hydroxyphenyl)-propane were obtained. This corresponds to a yield of 86.4% of theory. the resulting mixture was heated for 8 hours at 100° C in the reaction had been distilled off
