Abstract
A multistep process for producing amyl ketones is provided. In the process, a methyl ketone is reacted with butyraldehyde to form a C.sub.7 aldol condensation product which is then dehydrated to form an olefinic ketone and hydrogenated to form an amyl ketone. The process is suitable for coproduction along with the production of MIBK and yields products with a high selectivity.
