摘要：A copper catalyst obtained by reducing a copper compound with formaldehyde in the presence of an alkali in an aqueous medium is an excellent catalyst for the hydrolysis of an unsaturated nitrile to an amide. Furthermore, when a copper compound is combined with another element, which is selected from a specific group of elements, during the preparation of the copper catalyst, a catalyst is formed which has an increased hydrolysis activity and an increased catalyst lifetime.
