96.7 %Chromat. | With hydrogen In isopropyl alcohol at 150℃; for 2 h; Autoclave; Industrial scale | A 300-mL autoclave equipped with a stirring device was charged with 20 g of 4,4'-biphenol, 1 g of Raney nickel, and 80 g of 2-propanol, and a hydrogenation reaction was carried out for 2 hours at a hydrogen pressure of 6 MPa and a reaction temperature of 150°C. 2-Propanol was added to the obtained reaction solution until the crystals had completely dissolved. Then, filtration was carried out to obtain a reaction product solution from which the catalyst had been removed. Then, 21.4 g of crude 4,4'-bicyclohexanol (A) (purity: 96.7percent) was obtained by concentrating and drying this reaction product solution. |
