Abstract

A process for the selective hydrogenation of a material more unsaturated than a monoolefin to an olefinic material more saturated than the starting material comprises reacting the starting material with a hydrogen source, which is hydrogen and/or a primary or secondary alcohol, or a partially or completely hydrogenated single or fused ring aromatic hydrocarbon, in the presence of a high surface area hydrogenation catalyst and a solvent which is more strongly adsorbed on the catalyst than the desired olefinic product and which is an aldehyde, ketone, amine, phenol, ether or nitrile, e.g. acetone, methyl ethyl ketone, pyridine, piperidine, mono- or dimethyl aniline, phenol, hydroquinone, naphthol, cresol, dioxane or tetrahydrofuran. Materials which may be treated are cyclic or aliphatic diolefins or triolefins, aromatics and acetylenes; in particular cyclododecatriene-1,5,9 may be converted to cyclododecene. The catalyst may be Raney nickel, nickel deposited on kieselguhr, alumina or silica or iron, cobalt, copper, palladium, platinum, molybdenum, tungsten, chromium, their oxides or sulphides disposed on high surface area bases, e.g. having a surface area of 1-500 sq. metres/gm. The solvent may be used in amounts of 1-100% based on the starting material. The reducing agent other than hydrogen may be one which is itself oxidised to a suitable solvent, further solvent being optional. Specified hydrogen donors are cyclododecanol, cyclohexanol, sec. butanol and isopropanol. Temperatures of 20-400 DEG C. and pressures of 1-100 atmospheres may be used.
