Patent GB-486783-A (GB)
Title: Improvements in or relating to the hydration of olefines
IPC: C07C29/04
Filed: 1936-12-09
Abstract: Alcohols and ethers are produced by reacting olefines with steam or water in presence of a compound containing boron and a halogen, such as boron fluoride or an acid obtained by reacting hydrofluoric acid with boric acid or a borate.  The reaction may be effected by passing the reagents and a boron halide over pumice, silica gel, coke, or active carbon which may act as support for a metal halide such as an alkali, alkaline earth or amphoteric metal halide.  Or alcohols may be produced by passing an olefine into aqueous boron halide, which may contain 5 or more molecules of water per molecule of boron halide.  Boron fluoride is preferred, but the chloride bromide and iodide and also dihydroxyfluoboric acid and hydrofluoboric acids may be used.  The boron compound may be used alone or together with promoters such as nickel, nickel oxide, mercuric oxide or other metal or metal oxide.  The liquid phase process may be effected continuously at a temperature above the boiling point of the alcohol produced, which distils off continuously.  In a discontinuous process the olefine may be passed into a boron halide hydrate containing 2-3 molecules of water until saturated and then water is added and the alcohol distilled off; the water added is in such quantity as to leave a residue containing 2,5 molecules of water to one molecule of boron halide, which can be used again.  Atmospheric pressure or pressures of 25-900 atmospheres may be employed.  In examples: (1)-(3) ethylene or propylene, steam, and boron fluoride hydrate are passed over active carbon; (4) ethylene is passed under pressure into boron fluoride hydrate in a silver-lined tube; (5) ethylene is passed under pressure into boron fluoride hydrate in a silver-lined converter, and ethylene and water are introduced, giving a product containing ether and alcohol.  The apparatus may be lined with tantalum or copper or may be constructed of acid-resistant alloys of copper, molybdenum cobalt or tungsten.  Specification 486,877 is referred to.
