Dependent claims

Process for the production of 4,4-diphenylcyclohexanol (I)

characterized in that the compound of formula (II)
is dissolved in an organic solvent and then is hydrogenated in the presence of a nickel catalyst with hydrogen, whereby the reaction time is at least 1 minute, and the reaction temperature is 0° C. to 100° C., and the 4,4-diphenylcyclohexanol that is obtained is optionally purified.

Dependencies are inferred from the claim text.
