研究了Ni(naph)_2-Al(i-Bu)_2(n-OC_8H_(17))-BF_3·OEt_2[简称Ni-Al-B];[Ni(naph)_2+Bd]-Al(i-Bu)_2(n-OC_8H_(17))-BF_3·OEt_2[简称(Ni+Bd)-Al-B]和[Ni(naph)_2+Bd]-Al(i-Bu)_2(n-OC_8H_(17))-(BF_3·OEt_2+乙酸异戊酯)[简称(Ni+Bd)-Al-(B+EI)]三种催化体系的三元陈化液的配制及其在加氢汽油中对丁二烯的聚合行为。分别考察了Al/Ni、Al/B、Ni/Bd比等因素对催化活性的影响,结果表明:加小丁油(即在所用的油溶剂中加入微量的丁二烯)于三无陈化液中,可使陈化液稳定而不影响聚合活性;B-EI预混,在高Al/B比时增溶效果显著;Ni-Bd预混、B-EI预混均可大大加宽Al/B比的适宜范围;B-NMR谱表明,B、EI间存在交换反应。
Ni (naph) _2-Al (i-Bu) _2 (n-OC_8H_ (17)) - BF_3 · OEt_2 [Ni-Al-B] (N-OC_8H_ (17)) - BF_3 · OEt_2 [Ni (Ni + Bd) -Al-B] and [Ni (naph) _2 + Bd] -Al (i-Bu) _2 (n-OC_8H_ 17)) - (BF_3 · OEt_2 + isopentyl acetate) [abbreviation (Ni + Bd) -Al- (B + EI)] three ternary aging liquid system and its hydrogenation of gasoline in the Ding The polymerization behavior of dienes. The effects of Al / Ni, Al / B and Ni / Bd ratio on the catalytic activity were investigated respectively. The results showed that adding small amounts of butadiene oil (ie adding a small amount of butadiene into the oil solvent used) Liquid, the aging liquid can be stabilized without affecting the polymerization activity; B-EI premix, the solubilization effect is significant at high Al / B ratio; Ni-Bd premix, B-EI premix can greatly widen the Al / B ratio of the appropriate range; B-NMR spectroscopy showed that, B, EI exchange between the reaction.
