Abstract

Aliphatic alcohols are obtained by the hydration of olefines in presence of basic substances, especially hydroxides of alkali metals. The temperature may be 100-300 DEG C., and atmospheric, reduced, or increased pressure may be employed, but preferably, especially with gaseous olefines, pressure is employed which may be up to 50 atmospheres. If little water is present the product may be an alcoholate, but preferably sufficient water is used to produce alcohols. Liquid olefines may be heated or boiled with alkali hydroxide, preferably in concentrated aqueous solution; or gaseous olefines may be absorbed in circulating aqueous alkali; or a mixture of olefine and steam may be led in contact with aqueous or solid alkali supported on a carrier such as charcoal, silica gel, asbestos, or pumice. The alcohol may be separated by fractional condensation, or the alcohol and steam may be condensed together, the condensate being fractionally distilled with or without an entraining agent. Instead of alkali hydroxides there may be used other basic substances such as calcium or magnesium oxide, which may be used in admixture with one another or with alkali hydroxides. The basic substance may also be used in conjunction with other substances such as thoria or metals such as platinum, gold, silver copper, tungsten, and manganese, or their compounds. In examples (1) a mixture of equal volumes of ethylene and steam is passed into 50 per cent caustic potash solution at 150 DEG C. and 20 atmospheres pressure; (2) a mixture of 1 volume of ethylene and 2 volumes of steam is circulated over pumice impregnated with sodium hydroxide at 200 DEG C. and 30 atmospheres pressure; the vapours are cooled after each treatment or preferably after each ten treatments, the alcohol and steam being condensed together.
