CA 2025829

The present invention relates to a process for the preparation of alcohols by reaction of organic carbonyl compounds or mixtures containing organic carbonyl compounds with hydrogen over a supported catalyst containing nickel, aluminum oxide and zirconium dioxide at elevated temperature and if appropriate under increased pressure. Ketones, aldehydes and derivatives thereof are reacted as the carbonyl compounds at temperatures of 60 to 150°C.

a présente invention a trait à un procédé pour la préparation d'alcools par réaction de composés organiques carbonylés ou de mélanges contenant des composés organiques carbonylés avec de l'hydrogène sur un catalyseur sur support contenant du nickel, de l'oxyde d'aluminium et du bioxyde de zirconium à température élevée et, au besoin, sous pression accrue. Les composés carbonylés qu'on fait réagir à des températures de 60 à 150.degrés.C sont des cétones, des aldéhydes et des dérivés de ces produits.
