摘要: 以1-癸烯为原料、AlCl3-环己酮络合物为催化剂催化1-癸烯齐聚反应,考察三氯化铝络合催化剂的添加量、反应温度、反应时间、环己酮与AlCl3的摩尔比对聚α-烯烃合成油(PAO)收率及性能的影响。结果表明,在 AlCl3摩尔分数为5%、环己酮与A1C13摩尔比为0.5、反应时间为4 h、反应温度为25 ℃的条件下,PAO收率达到92%,100 ℃时的运动黏度为8.08 mm2/s,黏度指数达到174,是一种低黏度、高黏度指数的聚α-烯烃合成润滑油。色谱分析结果表明,合成的PAO产品中三聚体和四聚体所占比例最大,润滑油的理想组分含量大于85%。

Abstract: The oligomerization of 1-decenes was studied with aluminum chloride- cyclohexanone complex as catalyst. The effects of various conditions, such as catalyst amount, reaction temperature, reaction time and cyclohexanone/AlCl3 molar ratio on the yield and properties of poly-alpha-olefins (PAO) were studied. The experiment results show that under the conditions of an AlCl3 mole fraction of 5 %, cyclohexanone/AlCl3 molar ratio of 0.5, a reaction time of 4 h and a reaction temperature of 25℃, the PAO yield can reach 92 % with a viscosity of 8.08 mm2/s (at 100 ℃) and a viscosity index of 174, which indicates that the obtained product is a PAO synthetic lubricant with low viscosity and high viscosity index. As shown by GC analysis results, this PAO product is consisted of trimers and tetramers mainly, having more than 85% of ideal lube components.
