摘要: 使用AlCl3-异丙醇络合催化剂对1-癸烯齐聚反应进行研究,合成了高黏度聚α-烯烃合成润滑油(PAO)。考察了催化剂用量、反应温度、反应时间以及烯烃原料对PAO收率的影响。结果表明:在AlCl3摩尔分数为4%、异丙醇与AlCl3摩尔比为0.3~0.7、反应温度20~60 ℃、反应时间4 h的条件下,合成高黏度PAO的收率在90%以上,得到的聚α-烯烃合成润滑油具有低凝点、高黏度指数的特点。

Abstract: The oligomerization of 1-decenes was studied using aluminum chloride-isopropanol complex as catalyst, and high viscosity poly-alpha-olefins (PAO) were synthesized. The effects of reaction conditions, such as catalyst amount, molar ratio of isopropanol/AlCl3, reaction temperature, reaction time and various olefin feeds on the yield and property of PAO were investigated. The experimental results showed that under the conditions of an AlCl3 mole fraction of 4%, an isopropanol/AlCl3 molar ratio in the range of 0.3~0.7, reaction temperature in the range of 20~60℃ and a reaction time of 4 h, the yield of high viscosity PAO could be more than 90%, and the product having low condensation point and high viscosity index.
