Abstract

Substituted quinones are catalytically hydrogenated in the presence of a mixture of (1) low unbranched alcohols and (2) hydrocarbons which are inert and fluid under the conditions of the hydrogenation reaction and which may be aromatic, aliphatic or cycloaliphatic to economically produce corresponding substituted hydroquinones of high purity and low discoloration and in high yields thereof.
