| 摘 要： | 聚α-烯烃合成润滑油(PAO)是重要的合成润滑油之一。使用氯化铝-环己醇络合催化剂,对1-癸烯齐聚反应进行了研究,合成了不同粘度级别的中粘度PAO。考察了n(AlCl3)∶n(1-癸烯)、n(环己醇)∶n(AlCl3)、反应温度、反应时间、烯烃原料对PAO收率和性能的影响。实验结果表明:采用氯化铝-环己醇络合催化剂,以1-癸烯为原料,n(AlCl3)∶n(1-癸烯)=5∶100,反应时间4 h以上的条件下,在0.1~0.7范围内调整n(环己醇)∶n(AlCl3)或在20~80℃范围内改变反应温度,可以合成不同粘度级别的中粘度PAO。在上述条件下,PAO100℃运动粘度随n(环己醇)∶n(AlCl3)的增加而增大,随反应温度的升高而减小;PAO收率在85%以上,具有低凝点、高粘度指数的显著特点,是高质量的聚α-烯烃合成润滑油。

| Abstract: | Poly-alpha-olefins(PAO) synthetic lubricant is one of the important synthetic lubricants.Using aluminium chloride-cyclohexanol as complex catalyst,the oligomerization of 1-decenes was studied,and different viscosity grades of medium viscosity PAO have been synthesized.The effects of various kind of technological conditions,such as mole fraction of the catalyst,molar ratio of the cyclohexanol/AlCl3,reaction temperature,reaction time,olefin raw materials on the yield and propertie of the PAO were investigated... |
