Abstract

The invention comprises a process for the preparation of isophorone and its homologues from ketones of 3-6 C atoms by condensing the ketone or a mixture of such ketones with alkali hydroxide dissolved in an aliphatic, alicyclic or aromatic alcohol, with or without water present, and recycling higher condensation products, optionally with water for hydrolysis to isophorone and acetone. The products may be fractionated and part re-cycled. In examples, acetone is heated in an autoclave with 1/2 N-methanolic sodium or potassium hydroxide, or lithium hydroxide, under various conditions to give isophorone, mesityl oxide and other products, some fractionated and re-cycled; methyl ethyl ketone similarly gives methyl-3-heptene-3-one-4 and an isophorone of 12 C. Other alcoholic solvents specified include cyclohexanol and benzyl alcohol. Specification 524,151 is referred to.
