Benzene hexane → Dihydrophytol

참여 물질

반응 단계

Phytol (30.0 g, 0.101 mol) was dissolved in 200 ml of ethanol. A suspension of 1.8 g of Raney-Ni (W-1) in 5 ml of ethanol was added thereto, and hydrogenation was carried out under hydrogen for about 5 hours so that 2405 ml of hydrogen (theoretical volume at 24° C.; 2465 ml) was absorbed. After filtering off the catalyst through a filter paper, the ethanol was evaporated. Yield 29.9 g. Silica gel column chromatography with benzene-hexane (1:1) gave 24.7 g of the title compound (yield 82.3%).
