Participants

Reaction Steps

Ten % by weight (20 g) of Raney nickel was added to 4-(trans-4'-pentylcyclohexyl)phenol (200 g), and ethanol (1.8 l) was added to dissolve the phenol, followed by absorbing 3 mols of hydrogen based on one mol of the raw material phenol, into the solution at 100° C. under a hydrogen pressure of 20 Kg/cm2G. After completion of the hydrogenation, the catalyst was filtered off and ethanol was vaporized to concentrate the solution so as to give a volume of about 0.3 l, followed by adding fresh ethanol, recrystallization and filtration to obtain trans-4-(trans-4'-pentylcyclohexyl)cyclohexanol (77 g) (yield: 37.6%).
