실험 절차

Into a stainless steel autoclave were placed 500 g of 4,4'-(perfluoroisopropylidene)diphenol, 100 ml of isopropanol and 2 g of 5% ruthenium-carbon. The mixture was maintained at a temperature of 130° C. and a hydrogen pressure of 50 kg/cm2G for 40 minutes and then at 160° to 170° C. and a hydrogen pressure of 60 to 70 kg/cm2G for 40 minutes. After cooled to room temperature, the catalyst is filtered off and isopropanol was removed at a reduced pressure. The residue was recrystallized from toluene to obtain 290 g of 4,4'-(perfluoroisopropylidene)dicyclohexanol in the form of white solid.
