Abstract

Hydroaromatic alcohols containing a preponderance of the trans-form are prepared by the catalytic hydrogenation of the alkali metal salts of aromatic hydroxy compounds in aqueous or alcoholic solution. Examples are given of the conversion of sodium p-cresolate into trans-4-methylcyclohexanol and of the sodium compound of thymol into the racemate of natural menthol by treatment with hydrogen at elevated temperature in an autoclave in the presence of nickel. Other aromatic hydroxy compounds mentioned are the naphthols and oxybenzoic acids.ALSO:Hydroaromatic alcohols containing a preponderance of the trans-form are prepared by the catalytic hydrogenation of the alkali metal salts of aromatic hydroxy compounds in aqueous or alcoholic solution.
