摘要
采用Et3NHCl-AlCl3离子液体催化剂催化1-C12烯烃齐聚反应,考察了反应时间和温度对齐聚反应的影响。用色谱-质谱仪和红外光谱仪表征了产物的组成和结构,并按照石油和石油产品试验方法国家标准测定了产物的性能。结果表明,在反应时间为1~4h、温度为25~75℃的范围内,1-C12烯烃齐聚反应的产物主要是其三聚体、四聚体和五聚体,是具有长侧链的聚α-烯烃。该混合物具有高黏度(ν100为32.1~53.2mm2/s)、较高黏度指数(169~189)、低倾点(-33℃^-42℃)、适中相对分子质量(645~740)的特性,可作为高性能合成润滑油基础油。
Oligomerization of 1- The effects of reaction tempera -dodecene catalyzed by EtaNHC1-A1C13 ionic ture （25 -- 75 ℃ ） and reaction time （ 1 -- 4 h） liquid was carried out. on oligomerization were investigated. The composition and molecular structure of the obtained products were characterized by GC-MS and FT-IR methods. The viscosity, pour point and relative molecular mass of products were determined by the test method of national standards for petroleum and petroleum products. The results showed that the product was a mixture, mainly composed of trimers and tetramers and pentamers of 1-dodecene, and possessed high viscosity（v100 range of 32.1- 53.2 mm2/s）, high viscosity index（169--189）, low pour point（--33℃---42℃） and moderate relative molecular mass （645--740）, which is a lubricating base oil of high performance.
