Abstract:
A process for preparing saturated alcohols comprising effecting1) an aldol condensation of alkyl methyl ketones of 6 to 8 carbon atoms which are branched at the .beta.-carbon atoms with aldehydes of 5 to 15 carbon atoms which are branched at the .alpha.-carbon atom to form .alpha.,.beta.-unsaturated ketones and2) subsequent hydrogenation of the .alpha.,.beta.-unsaturated ketones to obtain saturated alcohols, wherein the aldol condensation is carried out at a temperature of 60-130.degree. C., in the presence of 30-55% strength aqueous solution of an alkali metal hydroxide and wherein the ketone which is branched at the .beta.-carbon atom, the aldehyde which is branched at the .alpha.-carbon atom and the alkali metal hydroxide present in aqueous solution are used in a molar ratio of (0.90-1.1):1:(0.15-1).
