摘　　要：用镍系催化剂，由丁二烯环化二聚制取１，５－环辛二烯。考察了催化体系中Ｐ与Ｎｉ、Ａｌ与Ｎｉ的摩尔比及溶剂等对反应转化率和选择性的影响，得到丁二烯环化二聚制１，５－环辛二烯的最佳试验条件：Ｐ与Ｎｉ的摩尔比为２．０，Ａｌ与Ｎｉ的摩尔比为３．０，反应温度１１０～１２０℃，反应时间２ｈ左右。Cyclooligomerization of butadiene with nickel complex catalysts has been extensively studied by Wilke and coworkers.In this paper,cyclodimerization of butadiene to 1,5 cyclooctadiene(COD) was investigated.The catalysts were Ni Al P system,Ni was Ni(acac) 2,Al was Al( i Bu) 3,and P was phosphine or phosphonic ester.The results show that phosphonic ester has better selectivity of COD than phosphine,the optimum ratios of P/Ni and Al/Ni were 2.0 and 3.0, respectively.
