Abstract
Aromatic compounds that are hydroxy-substituted on the aromatic nucleus can effectively be hydrogenated by contacting those compounds simultaneously with hydrogen and a catalyst comprising ruthenium supported by Cr.sub.2 O.sub.3 under alkaline conditions.
Claims3
A process for the hydrogenation of phenol which comprises admixing said phenol and an aqueous alkaline solution diluent having an alkali concentration such that the mol ratio of alkaline agent to phenol is in the range of 0.001 to about 2 mols per mol of phenol and treating the resulting admixture with hydrogen at a temperature in the range of 75.degree. to about 200.degree. C. and a pressure of about 225 to about 5000 psig in the presence of from 1 to about 10 parts by weight per 100 parts by weight of said phenol of a catalyst consisting essentially of 0.1 to 1.0 weight percent ruthenium on Cr.sub. 2 O.sub.3 whereby the hydrogenation is effected.
