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MoCl5-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。
The effects of the conditioiis of reaction between MoCl5 and,n-C7H15 COOH on thenumber of chlorine atorn in MoCl5 substituted by functional group C7H15 COO have beenstudied. The UV- Vis spectra of the exchange products MoCl5 m(n-C7H15 COO )m were dis-cussed and assigned. The catalytic activity of the molybdenum catalyst system containingMoCl,m(n-C7H15 COO)m for butadiene polymerization was found to be decreased rapidly withincreasing the number of substituted chlorine atoms in MoCl5.
