Abstract: Improved process for the manufacture of 2-ethylhexan-1-al by hydrogenating 2-ethylhex-2-en-1-al at temperatures of from 80* to 160*C and at pressures of from 10 to 250 atmospheres in an irrigation zone in the presence of fixed-bed catalysts comprising platinum, palladium or ruthenium supported on carriers, the improvement comprising feeding crude 2-ethylhexan-1-al to the irrigation zone in an amount which is from 2 to 10 times the amount of freshly introduced 2-ethylhex-2-en-1-al.
