摘　　要：研究以Ｌ酸和络合剂Ａ配制的络合物为催化剂，用于四聚丙烯齐聚制备二十四碳烯。在推荐工艺条件下：反应温度６０℃、时间６ｈ、Ｌ酸加入量为８．０％、络合剂Ａ与Ｌ酸的摩尔比为４．５１，二十四碳烯馏份收率大于６６％，达到文献报道的水平。本研究为合成磺酸盐添加剂的原料重碳烯烃的制备开辟了一条有效途径。The results on synthesis of tetracosene (C 24 olefins)by dimerization with a complex composed of Lewis acid (L) and complexing agent A as catalyst are reported.The yields of target compounds are not lower than 66% under the optimized reaction conditions:temperature 60 ℃,time 6 h,addition of A 8 0%,n(A)/n(L)=4 5,the product can be used as starting material for the preparation of sulfonate additives.
