Patent Abstracts

Oil-soluble aliphatic alcohols containing 8-18 C atoms per mol. are recovered from a solution in hydrocarbons by a 2-stage extraction process: this comprises (1) extracting the alcohol solution with an aqueous aliphatic alcohol solvent, such as MeOH, to obtain an extract consisting of the alcohol in the solvent and the hydrocarbon as raffinate; and (2) extracting the 1^st extract with a low-boiling hydrocarbon to separate the alcohol from the aqueous solvent. The low-boiling hydrocarbon is finally separated from the alcohol. The process is particularly applicable to the recovery of higher oxygenated compounds from crude oils obtained by the catalytic hydrogenation of CO.
