Title:
NEW RUTENIUM/CARBON-HYDROGENATION CATALYST
Document Type and Number:
Japanese Patent JPS5827642
Kind Code:
A
Abstract:
Ruthenium-on-charcoal and ruthenium-on-carbon black catalysts, containing from 0.1 to 5% by weight of iron, for the preparation of olefinically unsaturated alcohols by selective hydrogenation of the corresponding +60, beta -unsaturated carbonyl compounds in the liquid phase are prepared by modifying the catalyst with iron only after it has been impregnated with the ruthenium compound, and reducing the catalyst with hydrogen at from 400 DEG to 600 DEG C., with thorough mixing. The catalysts according to the invention are particularly useful for improving the industrially difficult hydrogenation of citral to give the soughtafter fragrances geraniol and nerol.
