Abstract
A process for the preparation of alcohols by reaction of organic carbonyl compounds or mixtures containing them with hydrogen over a supported catalyst containing nickel, aluminum oxide, and zirconium dioxide at elevated temperature and, if appropriate, under elevated pressure. Ketones, aldehydes and derivatives thereof are reacted as the carbonyl compounds at temperatures of 60.degree. to 150.degree. C.
Claims22
A process for the preparation of alcohols by reaction of organic carbonyl compounds selected from the group consisting of ketones and aldehydes, or mixtures containing said organic carbonyl compounds, with hydrogen at an elevated temperature in the presence of a supported hydrogenation catalyst wherein said catalyst contains 20% to 90% by weight of nickel, based on said catalyst, 1 to 30 parts by weight of aluminum oxide per 100 parts by weight of said nickel, and 0.5 to 20 parts by weight of zirconium dioxide per 100 parts by weight of said nickel, said nickel, aluminum oxide, and said zirconium dioxide being coprecipitated on a support,
- said process comprising reacting said carbonyl compounds at 60.degree. C. to 150.degree. C., in the presence of said catalyst.
