Abstract
Process for the co-production of ketones and mono-olefins from secondary alcohols and conjugated di-olefins in which dehydrogenation of the secondary alcohol and hydrogenation of the conjugated di-olefin are effected by contacting a mixture of the secondary alcohol and the conjugated di-olefin with a heterogeneous copper-containing catalytic system. The process is very useful for the co-production of methyl ethyl ketone and n-butenes from sec-butanol and butadiene at low temperatures (e.g. between 90.degree. C. and 130.degree. C.).
