摘要: 研究了MoCl5与n-C7H15COOH间的取代反应条件,如反应温度和时间等,对取代反应产物MoC15-m(n-C7H15COO)m的影响,讨论了产物的紫外可见光谱,测定了由取代产物组成的铝催化剂对丁二烯聚合反应的活性,结果表明,随着MoCl5中氯的取代量(m=2~4)的增加聚合活性迅速降低。

Abstract: The effects of the conditioiis of reaction between MoCl5 and n-C7H15COOH on the number of chlorine atorn in MoCl15 substituted by functional group C7H15COO have been studied. The UV-Vis spectra of the exchange products MoCl5 m(n-C7H15COO)m were discussed and assigned. The catalytic activity of the molybdenum catalyst system containing MoCl5 m(n-C7H15COO)m for butadiene polymerization was found to be decreased rapidly with increasing the number of substituted chlorine atoms in MoCl5.
