摘　　要：介绍了在Ｔ－９９新型固体磷酸催化剂作用下混合丁烯齐聚反应的研究。反应在空速３ｈ－１，超临界相态（对比压力Ｐｒ≥１，对比温度Ｔｒ≥１）－近临界相态（Ｐｒ≥１，Ｔｒ＜１）结合的条件下进行。反应温度从１８０℃提高到２３０℃，混合丁烯转化率由７５％上升到９４％，产物中二聚物异辛烯选择性ＳＣ８在７８％～９１％，十二烯选择性ＳＣ１２在６％～１０％，ＳＣ８与ＳＣ１２之和达到９０％以上。The article is a study about oligomerization of mixed butylenes by the catalysis with a new type solid phosphorus acid catalyst. Tests were carried enough at space velocity 3 h-1, supercritical state(relative press Pr ≥1, relative temperature Tr ≥1) - subcritical state(Pr≥1, Tr ＜ １). Transformation of mixed butylenes be raised from 75% to 94% when reactive temperature is going up from 180℃ to 230℃. Selectivity of isooctene SC8 is between 78% -91%, selectivity of dodecene SC12 is at 6% - 10%. The sum Of SC8 and SC12 is above 90%.
