ABSTRACT:
Aldehydes can be condensed with ketones or aldehydes to produce higher aldehydes or ketones by contacting the materials to be condensed with a nonzeolitic molecular sieve. The condensation may be carried out in the presence of hydrogen to give as product a saturated aldehyde or ketone. The ketone and/or aldehyde may be generated in situ by dehydrogenation of an alcohol, and the hydrogen thus liberated used to effect hydrogenation of the immediate unsaturated product of the condensation, thereby producing as the final product a saturated aldehyde or ketone. The non-zeolitic molecular sieves can achieve improved conversion rates and selectivities as compared with conventional catalysts for the reaction.
