摘要

Abstract

Hydrogenation of SBS using RuCl2(PPh3)3 as catalyst and PPh3 as ligand was studied for the first time.Hydrogenated Degree of hydrogenation of SEBS reaches 98%.RuCl2(PPh3)3 which was used as catalyst has high activity and high selectivity (phenyl is not hydrogenated)

and gel will not be formed.The band of C C was saturated.So that RuCl2(PPh3)3 has high selectivity.It is shown that the thermal resistance was improved greatly by initial decomposition temperature.Rh-Ru double metal new catalytic system has higher activity than Ru single metal system in hydrogenation of SBS.
