摘要: A process for the catalytic hydrogenation of butterfat where non-deacidified is continuously reacted with hydrogen under pressures from 20 to 300 bar and at temperatures 180° 250° C. molar ratios fatty acid residue in 10:1 500:1. The reaction carried out over catalysts which contain 30 40% by weight copper, 23 30% chromium, 1 10% manganese, silicon, 7% barium. percentages each case are based on total oxidic mass catalyst. Other transition metals, especially zirconium cerium, additionally incorporated into metals catalyst converted their oxides calcination. shaped particulate or granulated elements least one binder addition graphite. activated a hydrogen-containing gas mixture. products include alcohols, oxo- hydroxyfatty alcohols corresponding natural composition desired, valuable product, propylene glycol. This advantageous since it eliminates need preseparation relatively short-chain acids (or deacidification) prior hydrogenation.
