摘要：
Hydrogenation of 1,4-benzoquinone was investigated at 25-50-degrees-C and atmospheric pressure on Raney nickel in an aqueous medium. It was shown that in addition to hydroquinone, cyclohexanol and oligomers are formed during hydrogenation. Treating the catalyst with sulfur-containing compounds [(5-9).10(-5) g of sulfur per 1 g of Ni(Ra)) inhibits hydrogenation of the aromatic ring and increases the yield of hydroquinone.
