摘要/Abstract

摘要： 开展了BF₃/乙酸络合物催化1-癸烯合成低黏度聚α-烯烃润滑油基础油的实验研究，考察了反应温度、压力、时间、催化剂用量和催化剂回用工艺对反应产物组成和聚α-烯烃（PAO）产品性能的影响，结果表明：在反应温度为30℃、反应压力为0.2MPa、反应时间为2h、新鲜BF₃/乙酸络合物与1-癸烯的质量比为1∶100的条件下，1-癸烯转化率大于99.4%，PAO收率大于95.7%，产品的100℃运动黏度为4.33mm²/s，黏度指数为134，倾点为–53℃；采用BF₃/乙酸络合物回用工艺可有效降低生产成本，减少污染排放，但回收络合物的催化活性有所下降，向催化体系补充部分新鲜络合物后，产物组成及PAO性能与采用新鲜络合物时基本一致。

Abstract: In this paper, we prpared low viscosity poly-alpha-olefin base oil from 1-decene with BF₃/acetic acid as the catalyst. We investigated the effects of reaction temperature, reaction pressure, reaction time, BF₃/acetic acid complex dosage and the recycle of BF₃/acetic acid complex on the performance of PAO products. Experimental results showed that when the reaction was taken place at temperature of 30℃, pressure of 0.2MPa, and with reaction time of 2h, and the mass ratio of fresh BF₃/acetic acid complex to 1-decene of 1:100, the conversion rate of 1-decene was > 99.4%, and the yield of PAO was > 95.7%, The kinematic viscosity of the obtained product at 100℃ was 4.33mm²/s, and the viscosity index was 134, the pour point was -53℃. The recycling of BF₃/acetic acid complex can effectively reduce the production costs and the pollution emissions, but the catalytic activity was decreased. However, when some fresh BF₃/acetic acid complex were added into the recycled ones, the composition and PAO performance of the products were almost the same as those produced with fresh complexes.
