PROCEDEU DE OBTINERE A UNUI CATALIZATOR PENTRU PRODUCEREA ALCOOLILOR ALIFATICI

摘要

Manufacture of saturated aliphatic alcohols by hydrogenation of saturated aliphatic aldehydes at temperatures of from 140 DEG to 230 DEG C at pressures of from 50 to 350 atmospheres in the presence of catalysts containing from 5 to 15% by weight nickel and 5 to 20% by weight molybdenum supported on silicic acid, in which process catalysts are used which have been obtained by heating silicic acid carrier materials to temperatures of from 700 DEG to 1200 DEG C, impregnating the resulting silicic acid carrier materials with nickel and molybdenum salts, drying the resulting material with or without further heating to temperatures of from 200 DEG to 500 DEG C and subsequently treating the product with hydrogen at elevated temperature in conventional manner. The alcohols obtained are used as solvents or for the manufacture of plasticizers for polyvinyl chloride.
