  structures and acidities. The influence of different ionic liquids, ionic liquid loading, different co-catalysts, catalyst ratios (mole ratio of ionic liquid to co-catalyst), reaction time, pressure, temperature, solvent, source of reactants, and the recycling of catalyst systems was studied. Among the synthesized ionic liquids, 1-(4-sulfonic acid)butyl-3-hexylimidazolium hydrogen sulfate ([HIMBs]HSO4) exhibited

  摘要 研究了以布朗斯台德酸性离子液体为主催化剂，三辛基甲基氯化铵为助催化剂的新型催化剂体系催化的烯烃低聚反应。合成的布朗斯台德酸性离子液体通过傅里叶变换红外光谱 (FT-IR)、紫外-可见光谱 (UV)、1H 核磁共振 (NMR) 和 13C NMR 进行表征，以分析其结构和酸度。不同离子液体、离子液体负载量、不同助催化剂、催化剂比（离子液体与助催化剂的摩尔比）、反应时间、压力、温度、溶剂、反应物来源和催化剂体系回收率的影响为学习了。在合成的离子液体中，1-(4-磺酸)丁基-3-己基咪唑硫酸氢盐([HIMBs]HSO4)在测试的反应条件下表现出最好的催化活性。在最佳反应条件下，异丁烯的转化率和三聚体的选择性分别为83.21%和35.80%。此外，催化剂体系易于分离和重复使用；根据实验产物的分布提出了一种可行的反应机理。

  Etherification of glycerol by isobutylene was conducted in a batch mode using acidic and partially neutralized Amberlyst-15 ionic resin p-toluenesulfonic acid silicotungstic acid cesium salt of silicotungstic acid and ionic liquid containing sulfonic acid groups All the catalysts are comparable in terms of the initial rate of glycerol conversion into mono-ether (except cesium salt of heteropolyacid) but differ substantially with respect to the yields of higher ethers of glycerol Ionic liquid and heteropolyaad are immiscible/insoluble in higher ethers of glycerol As a result they have unique capability of suppressing the formation of tri-ether during the initial stage of glycerol conversionAcidic Amberlyst-15 in the form of fine powder has the highest activity per unit weight for glycerol etherification and relatively high activity in isobutene oligomerization Partial exchange of acidic protons with cations Na+ Ag+ Mg2+ and Al3+ decreases the rates of all the processes but isobutylene oligomenzation is suppressed more efficiently Ag+- and Al3+-modified Amberlyst demonstrates higher yields of tri-ether and has specific pattern of interaction with gaseous isobutene distinctive to other metal-substituted Amberlysts (C) 2010 Elsevier B V All rights reserved
