【摘要】：以自制混合癸烯为原料,采用AlEt_2Cl和AlEt_3两种助催化剂与TiCl_4形成双助催Ziegler-Natta体系,制备出高黏度指数的聚α-烯烃合成润滑油基础油(PAO)。利用GC表征和黏度测定的方法研究了反应条件对PAO收率和黏温特性的影响。实验结果表明,采用AlEt_2Cl-AlEt_3双组分助催化剂制备PAO,PAO的收率和黏度指数较高。适宜的PAO制备条件为:TiCl_4用量2%(w)(基于混合癸烯的质量)、反应温度80℃、铝钛摩尔比为1.4∶1,在该条件下,所得PAO的100℃运动黏度为30 mm2/s,黏度指数135。推测了该催化体系催化癸烯合成PAO的反应机理。双助催Ziegler-Natta体系催化混合癸烯得到的PAO具有中等黏度和高黏度指数的特点,在润滑油领域具有很大的发展潜力。
[Abstract]:Using self-made mixed decene as raw material, poly伪-olefine base oil (PAO). With high viscosity index was prepared by using AlEt_2Cl and AlEt_3 co-catalysts and TiCl_4 to form a double catalytic Ziegler-Natta system. The effects of reaction conditions on the yield and viscosity temperature of PAO were studied by GC characterization and viscosity measurement. The experimental results show that the yield and viscosity index of PAO,PAO prepared by AlEt_2Cl-AlEt_3 two-component cocatalyst are high. The optimum preparation conditions of PAO are as follows: the amount of TiCl_4 is 2% (w) (based on the mass of mixed decene), the reaction temperature is 80 鈩，
