摘要/Abstract

摘要： 采用季戊四醇为引发剂、BF3为催化剂催化1-癸烯齐聚反应，在BF3气体压力一定（常压，呈鼓泡状）的条件下，考察了季戊四醇与1-癸烯质量比、反应时间、反应温度对1-癸烯齐聚反应的影响、最佳工艺条件下1-癸烯齐聚的效果以及季戊四醇的可循环性。对齐聚产物进行了气相色谱表征。结果表明：1-癸烯与季戊四醇质量比为10、反应时间为2.5 h、反应温度为20 ℃时，1-癸烯齐聚反应的转化率高达97.90%，齐聚产物中三聚物与四聚物之和所占质量分数高达84.17%；该齐聚产物可用于制备高性能合成润滑油基础油；季戊四醇的循环利用效果良好。

Abstract: 1-decene oligomerization was studied using pentaerythrotol as initiator and BF3 as catalyst. The effect of mass ratio of pentaerythrotol/1-decene, reaction time and temperature on the reaction as well as the best conditions for 1-decene oligomerization and the recyclability of pentaerythrotol were investigated. The oligomerization products were analyzed by gas chromatography. The results indicate that at the conditions of mass ratio of 1-decene/pentaerythrotol of 10, 20 ℃ and 2.5 h, the conversion of 1-decene oligomerization is up to 97.90%. The yield of trimer and tetramer together is 84.17%. The recycling effect of pentaerythritol is good. The product can be used to prepare high performance synthetic lubricant base oil.
