Catalysts for the amination of alkylene oxides, alcohols, aldehydes and ketones

摘要

A catalyst comprising, based on the total weight of the catalyst, more than 6-50% by weight of cobalt, nickel or a mixture thereof, 0.001-25% by weight of ruthenium, 0-10% by weight of copper and 0-5% by weight of promoters on a porous metal oxide carrier can be prepared by (a) impregnating the carrier with the metals, promoters or compounds thereof, (b) drying and calcining the impregnated carrier and (c) reducing the calcined carrier in a stream of hydrogen, carrier not being impregnated with halogen compounds.
