摘要
本文报道了 (BF_3·0Et_2+n—C_8H_(17)OH)(简称Ni—Al—B)体系催化丁二烯聚合动力学研究结果,得到聚合速率方程式为 -d[Bd]/dt=k[Ni]~0[A1]^(-1)[B]~0[Bd],A1/B≤1 -d[Bd]/dt=k′[Ni]~0[A1]^(-1)[B][Bd],A1/B>1 聚合表观活化能为49.2kJ·mol^(-1)。
Kinetics on the polymerization of butadiene with (BF_3OEt_2 +n—C_8H_(17)OH)(called as Ni—Al—B)system as catalyst has been studied, The result shows that the rate is around zero order reaction on [Ni] and is around negative first order reaction on [Al]. It is suggested that the rate equation of the polymerization is - d[Bd]/dt = k'[Ni]~0[Al]^(-1)[B]~0[Bd] Al/B≤1 - d[Bd]/dt =k'[Ni][Al]^(-1)[B][Bd] Al/B>1 The apparent activation energy for the polymerization is 49.2 KJ.mol^(-1).
