摘要
以三(三苯基膦)二氯化钌[RuCl2(PPh3)3]为催化剂 ,三苯基膦(PPh3)为配体对苯乙烯 -丁二烯嵌段共聚物(SBS)加氢 ,在150℃下进行了SBS加氢动力学研究 ,得到了加氢动力学方程 :-d[C C]/dt=k[H2]1.12[C C][Ru *][PPh3]-1 ,130～160℃的加氢反应活化能为22.74kJ/mol。
Kinetics of hydrogenation of SBS using RuCl2(PPh3)3 as catalyst and PPh3 as ligand was studied.The kinetics equation of hydrogenation(150 ℃) was obtained:-d/dt=k1.12-1,and the activation energy of hydrogenation (130～160 ℃) was 22.74 kJ/mol .
