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[CC]/dt=k[H2]1.12[CC][Ru][PPh3]-1,130~160℃的加氢反应活化能为22.74kJ/mol。

Abstract: 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[C=C]/dt=k[H2]1.12[C=C][Ru][PPh3]1,and the activation energy of hydrogenation (130160 ) was 22.74 kJ/mol .
Keywords:styrene
butadiene block copoly mer;tris(triphenylphosphine)ruthenium chloride;catalytic hydrogenation; kinetics
