摘要
以氯化1-丁基-3-甲基咪唑[Bmim]Cl为阳离子、氯化铁为阴离子合成酸性离子液体作为催化剂,用于内烯烃的齐聚反应,考察了不同反应温度、反应时间、催化剂用量等工艺条件对内烯烃齐聚反应的影响。通过气相色谱分析可知,合成的聚内烯烃主要是二聚、三聚、四聚和较少的五聚物,没有裂解产品。并在温度为120℃,反应时间为3h,催化剂质量分数为5%的条件下,内烯烃的转化率最高达到82%,这为进一步工业化合成高质量的聚内烯烃类润滑油提供了有效数据。
The experiment used internal-olefins as raw materials, Acidic ionic liquid which were synthesized from [Bmim]Cl and FeC13 as catalyst for the synthesis of poly-internal-olefins ,examined the influence of different temperature, reaction time, use level of Acidic ionic liquid on synthesis of PIO and internal-olefins polymerization conversion rate. The better conditions of PIO synthesis were that the reaction temperature is 120℃, the reaction time is 3h, and the use level of catalyst is 5% .Under the better conditions throught gas chromatography analysis of the product, results as follows： The components of oligomerization product were the mixture of dimer, trimer, tetramer and pentamer without craekate and the conversion of internal-olefins was 82%.Thus, PIO can made the high quality synthetic lubricating oils and this work provided a valuable data for studying the PIO synthetic lubricant in industry.
