실험 절차

Into a 500 ml-volume glass-made reactor equipped with a condenser tube, 5.00 g of 2,3,5,6-tetrafluorobenzonitrile, 51.00 g of methanol, 52.00 g of water, 45.00 g of acetic acid and 0.50 g of sponge nickel were charged. After purging the vapor phase moiety with hydrogen gas, the mixed solution was stirred at 60° C. under atmospheric pressure while continuously supplying hydrogen. As the time passed, the reaction solution was sampled and analyzed by means of a gas chromatograph. As a result, it was confirmed that 2,3,5,6-tetrafluorobenzyl alcohol was produced together with 2,3,5,6-tetrafluorobenzaldehyde. The yields in the reaction solution are shown in the table below.
