Abstract

Mixtures of synthetic alcohols containing at least 8 carbon atoms are separated into components of different melting-point by allowing the partly or completely melted mixture to solidify incompletely and separating solid and liquid components by pressing. Organic solvents, containing 1-11 carbon atoms, e.g. hydrocarbons, their halogen derivatives, alcohols, esters, and ethers, if desired containing water, may be present in amounts of up to 15, generally only a few per cent. Using mixtures of not too wide boiling range, straight chain, and branched alcohols of different degrees of branching may be separated. Pressing is effected in an ordinary press, usually at a temperature not substantially below normal. The liquid fraction may be further cooled to separate solid. Products of fatty acid reduction, Oxo syntheses or carbon monoxide hydrogenation may be separated to give alcohols for use in the lubricants, textile, detergent, cosmetic, and like industries. In examples: (1) a C18 average fatty alcohol mixture is heated to 70 DEG C. and slowly cooled for 12 hours, the solid cake about 3 cms. thick being wrapped in a filter cloth and pressed at 17 kg./cm.2 at 20 DEG C.; (2) a C16-C28 mixture is melted and slowly solidified to a 5 cm. cake which is pressed at 20 DEG C. and 50 kg./cm.2; (3) the mixture of (1) is melted and treated with 5 per cent of methanol, ethanol, benzine, C6-C9 fatty acids, acetone or glycerol monomethyl ether, cooled, and pressed at 24 DEG C. and 34 kg./cm2.
