|
摘要
以1-癸烯为原料,Al Cl3-乙醇络合物为催化剂,在1-癸烯用量为10 t,反应温度为120~125℃,反应压力低于0.4 MPa,络合催化剂采用分4批加入(每批反应时间为30 min)且总质量分数为4.0%的条件下,可以制备聚α-烯烃(PAO)合成油,并对产物进行了蒸馏分离。结果表明:馏程分别为>220~270,>270℃的馏分黏度指数分别大于120.0,130.0,二者收率分别为21%,51%;PAO总收率达到83%。
Poly- α- olefin synthetic oil was prepared with 1- decene as raw material,aluminum chloride- alcohol complex as catalyst at material amount 10 t,reaction temperature 120- 125 ℃,reaction pressure less than 0. 4 MPa,adding complex catalyst at 4 batches( reaction time 30 min at each batch) and its total mass fraction 4. 0%,and products were separated by distillation. The results showed that when the distillation range was > 220-270,> 270 ℃,the viscosity index of distillation cut was more than 120. 0,130. 0 respectively,and the yield of them was 21%,51% separately. The total yield of PAO reached 83%.
