摘要
使用三氯化铝作催化剂,对C_(13)～C_(14)内烯烃齐聚反应进行了研究,考察三氯化铝用量、反应温度和反应时间等工艺条件对聚内烯烃合成油收率的影响,确定了最佳工艺条件:三氯化铝用量为原料总质量的3%,反应温度160℃,反应时间4 h。在此条件下,以C_(13)～C_(14)内烯烃与1-十四碳烯的混合物为反应原料合成了聚烯烃合成油,并研究了其物化性能。结果表明,采用质量分数各为50%的1-十四碳烯与C_(13)～C_(14)内烯烃混合物,可以合成100℃黏度为6.10 mm^2·s^(-1)、黏度指数147和凝点-40℃的聚烯烃合成油,收率为78%,具有黏度低、凝点低和黏度指数高的特点,是高质量的聚烯烃合成油。
Oligomerization of C13 --C14 internal olefins was studied using aluminum chloride as the catalyst. Effects of the dosage of aluminum chloride catalyst, reaction temperature and reaction time on the yield of poly-internal-olefins（PIO）synthetic lubricant were investigated. The optimum reaction condition was obtained as follows： mass fraction of the aluminum chloride catalyst =3%, reaction temperature 160 ℃, reaction time 4 h. Poly-olefins lubricant was synthesized under the optimum condition from mixture of C13 -C14 internal olefins and 1-tetradecene, and its properties were investigated. The experiment results showed that high-quality poly-olefin synthetic lubricant was obtained using mixture of 50% mass fraction of 1-tetradecene and 50% mass fraction of C13 - C14 internal olefins as the feedstock, with poly-olefins lubricant yield of 78%, viscosity at 100 ℃ of 6. 10 mm^2·s^-1, viscosity index of 147, condensation point of -40 ℃.
