Abstract

a -Ethyl-b -isopropyl acrolein is prepared by subjecting a mixture of n-butyraldehyde with an at least 50 per cent by weight excess of isobutyraldehyde to the action of an aqueous solution of a water-soluble strongly alkaline substance at temperatures between 60 DEG C. and the boiling-point of the reaction mixture. The preferred condensing agents are sodium and potassium hydroxide solutions and the reaction is preferably carried out in an inert atmosphere, e.g. nitrogen or carbon dioxide. Some aldol may be obtained as a by-product. The mixture of unchanged isobutyraldehyde and a -ethyl-b -isopropyl acrolein may be hydrogenated to give a mixture of isobutanol and a -ethyl-b -isopropyl propanol. In the examples a mixture of isobutyraldehyde and n-butyraldehyde is heated in the presence of caustic soda solution to give a -ethyl-b -isopropyl acrolein which is catalytically hydrogenated to give 4-methyl-2-ethyl-pentanol-1.
