Abstract
Alcohols are produced by a process comprising reacting an olefine with hydrogen and carbon monoxide in the presence of a hydroformylation reaction catalyst at elevated temperature and pressure to produce a mixture containing an aldehyde having one more carbon atom than the starting olefine, unreacted hydrogen, carbon monoxide and olefine, dissolved catalyst and polymeric material; removing from the mixture the unreacted hydrogen and carbon monoxide and dissolved hydroformylation catalyst; fractionating the remaining mixture in the presence of steam to remove at least some of the unreacted olefine; subjecting the remainder of the mixture to catalytic hydrogenation to obtain an alcohol product; and thereafter recovering the alcohol from the product. Mono-olefines or diolefines and straight or branched olefines or cyclo-olefines may be used as starting materials. Hydrogen to carbon monoxide molar ratio may vary from 0.75 : 1 to 5 : 1. The preferred temperature range for the hydroformylation is 149-191 DEG C. and the preferred pressure is above 105 kg./sq. cm. The preferred hydroformylation catalyst is a cobalt salt of an organic acid, e.g. the octanoate or naphthenate. At least one mol. of hydrogen and of carbon monoxide is used for each mol. of olefine. The cobalt carbonyl and other metal carbonyls which may be present can be removed, for example, by passing the hydroformylation product through a heated zone packed with pumice, preferably at 93-204 DEG C. and under a pressure of 1.75-35 kg./sq. cm. In this zone unreacted synthesis gas and carbon monoxide may be removed. The remaining gas is then fractionated in the presence of steam, preferably at 38-288 DEG C., and a pressure of 0.07 to 3.5 kg./sq. cm., to remove at least some of the unreacted olefine and the remainder of the product is passed to the hydrogenation zone. Preferably nickel is used as catalyst and the hydrogenation is carried out at 121-232 DEG C. and at a pressure of 35 to 140 kgs./sq. cm.
