A Ziegler - type catalyst for the homogeneous hydrogenation of C5 fractions has been developed. It has been discovered that the cativity and the yield of hydrogenation were higher and the reaction conditions were more temperate than heterogeneous catalytic hydrogenation under a tiny amount of the catalyst. The most favoured reaction conditions were that the concentration of the catalyst was (200～400) ×10-6, the temperature was 60～ 80℃, and the pressure was 0. 8～ 1. 0MPa. The hydrogenated C5 fractions was easy to be seperated, and from it, three pentanes products bas been obtaoned with the purity over 95 %.The technological process of hydrogenation and seperation of C5 had been advanced.
