Abstract
Controlling the average pore diameter of alumina-supported platinum or rhodium catalysts used for dehydrogenating lower secondary alcohol to ketones affects the product distribution. A large pore diameter gives high selectivities to the ketone corresponding in carbon number to the alcohol feed, whereas a small pore diameter permits coproduction of this lower ketone and economically attractive amounts of higher ketone condensation products.
