Abstract

PURPOSE: To purify the titled compound, by partially hydrogenating a diolefin, having the same carbon atoms, and contained in the titled compound in a low concentration selectively in the presence of a compound oxide catalyst containing two or more oxides of titanium, tungsten, zirconium and silicon.
CONSTITUTION: A diolefin, having the same carbon atoms as a monoolefin, and contained in a hydrocarbon mixture containing the monoolefin mostly is selectively and partially hydrogenated in the presence of a compound oxide catalyst containing two or more compounds selected from oxides of titanium, tungsten, zirconium and silicon and converted into the monoolefin. According to the method, the diolefin can be partially hydrogenated into the monoolefin in a high selectivity, and the monoolefin is scarcely hydrogenated. Therefore, the method is applicable to the purification of the monoolefin. The presence of a large excess of hydrogen suppresses side reactions, e.g. polymerization or coking.
