Abstract
A process whereby 4-t-butylcyclohexanol with a high content of the cis-isomer, which is useful as a perfume ingredient, can be economically produced on an industrially available scale at a low cost. The process comprises hydrogenating 4-t-butylcyclohexanone by using a specific ruthenium-phosphine complex as a catalyst in the presence of a base containing an alkali metal and an alkylenediamine having from 1 to 6 carbon atoms.
