Abstract: A process to produce Methyl Amyl Ketone heterogeneously via the cross-aldol condensation reaction between a C.sub.3 (isopropanol or acetone feed) and a C.sub.4 (butanol or butyraldehyde feed). The catalyst, hydrogen reduced copper oxide on gamma alumina, produces both high reactivity and long catalyst lifetimes. The catalyst is successfully regenerated. Efficiencies to MAK range from 50 to 80 wt. % and efficiencies to useful products range from 75 to 95 wt. % depending on the composition of the feed and temperature. Temperatures range from 200.degree. to 262.degree. C.In general, this catalyst readily catalyzes the cross-aldol condensation reaction between aldehydes (or primary alcohols) and ketones (or secondary alcohols) to produce higher molecular weight ketones; likewise, this catalyst catalyzes the aldol condensation reaction between the same or different ketones to again produce higher molecular weight ketones.

Abstract: Saturated aliphatic aldehydes are prepared by contacting diesters of carbonic acid with synthesis gas and a Group VIII compound, preferably a cobalt compound, a halogen, and optionally a Group V trivalent ligand.
