Abstract
Abstract A hydroformylation process comprising the treatment of an unsaturated compound with carbon monoxide and hydrogen in the presence of a catalyst comprising a cobalt-containing compound is improved by the presence of a zeolite which has been dispersed in an alumina hydrosol prior to aging at elevated temperatures.
