Abstract

1462328 2-Ethylhexanol RUHRCHEMIE AG 31 July 1975 [7 Aug 1974] 32074/75 Heading C2C 2-Ethylhexanol is produced continuously by subjecting n-butyraldehyde to aldol condensation at 80-140‹ C. with aqueous alkali metal hydroxide and eliminating the elements of water from the condensate, to give an intermediate product containing 2-ethylhexenal and heavier condensates, evaporating 2-ethylhexenal from the intermediate product and hydrogenating it in the vapour phase to 2-ethylhexanol, and recycling from the evaporation step to the aldol condensation a residue comprising heavier condensates. The amount recycled is preferably 4-8% by weight of the 2-ethylhexenal fed to the hydrogenation step, and the recycled residue preferably contains 40-70% 2-ethylhexenal. The raw aldolization product may be scrubbed with water.
