Abstract

A process for hydrogenation of an aldehyde selected from the group consisting of propanal, n-butanal, and i-butanal comprising contacting said aldehyde with hydrogen in the presence of a hydrogenation catalyst comprising in the reduced state PA1 25% to 50% by weight of metallic nickel PA1 10% to 35% by weight of nickel oxide PA1 4% to 12% by weight of magnesium oxide PA1 1% to 5% by weight of sodium oxide PA1 the remainder being a water insoluble support material, wherein the total of said nickel and said nickel oxide is 40% to 70% by weight based on said catalyst, said catalyst having a total BET surface area of 80 to 200 m.sup.2 /g and a total pore volume, determined by mercury porosimetry, of 0,35 to 0.6 ml/g, said total volume consisting of 30% to 60% of said volume from pores having pore radii equal to or less than 40 .ANG., 4% to 10% of said volume from pores having pore radii from more than 40 .ANG. to 300 .ANG., and 30% to 60% of said volume from pores having pore radii from more than 300 .ANG. to 5000 .ANG..
