摘要:

用煤基混合烯烃分离出的C12-C16烯烃馏分为原料,在氮气保护下用AlCl3催化聚合,研究聚合温度、聚合时间、聚合压力及催化剂质量对聚α烯烃合成油收率的影响,确定最佳聚合反应条件,并对产物进行物性分析。结果表明,冷阱油中C12-C16烯烃的蒸出温度在214~274 ℃。在聚合温度为137 ℃、聚合时间为40 min、聚合压力为4.0 MPa和催化剂质量为10 g的条件下,聚合反应收率为84.57%,所得聚α烯烃合成油在40 ℃时的运动黏度为32.53 mm2/s,闪点为221 ℃,凝点为-53 ℃,溴值为9.6 g(Br)/(100 g)。

Abstract:

The C12-C16 olefin fractions were separated by distillation from coal chemical mixed olefins. The obtained C12-C16 olefins were used as raw materials to synthesize polyalphaolefin (PAO) by AlCl3 catalyst. The influence of polymerization temperature, polymerization time, polymerization pressure and amount of catalyst were researched. The optimum polymerization conditions were determined. The physical properties of the product were analyzed. The results show that the evaporation temperature of C12-C16 olefins in cold trap oil is 214~274 ℃. Under the conditions of polymerization temperature of 137 ℃, polymerization time of 40 min, polymerization pressure of 4.0 MPa and catalyst mass of 10 g, the polymerization yield is 84.57%, and the kinematic viscosity of obtained PAO product at 40 ℃ is 32.53 mm2/s, the flash point is 221 ℃, the freezing point is -53 ℃, and the bromine value is 9.6 g(Br)/(100 g) .
