三氟甲磺酸催化1-己烯齐聚反应的研究

使用三氟甲磺酸作催化剂对1-己烯齐聚反应进行研究。考察三氟甲磺酸催化剂用量、反应温度和反应时间等工艺条件对产物聚α-烯烃收率的影响。确定了最佳工艺条件：催化剂用量1.0 mL，反应温度50 ℃，反应时间3 h，此条件下，1-己烯转化率约为90%，产物主要是二聚物、三聚物、四聚物和五聚物，没有裂解产品。为进一步工业化开发聚α-烯烃合成油提供了基础数据。

Study on 1-hexene oligomerication catalyzed by trifluoromethanesulfonic acid

The oligomerization of 1-hexene using trifluoromethanesulfonic acid as the catalyst was studied. The effects of catalyst dosage, reaction temperature and reaction time on the yield of the poly-alpha-olefins were investigated. The optimum technologic condition was as follows ： catalyst dosage 1.0 mL, reaction temperature 50 ℃ and reaction time 3 h. The components of the product were analyzed using gas chroma- tograph, and the results showed that 1-hexene conversion was about 90% , and the product was the mixture of dimer, trimer, tetramer and pentamer without crackate.
