摘要
以 1，4-二氮杂双环[2.2.2]辛烷（DABCO）和多种卤代烃为原料，制备了一系列碱性功能离子液体，然后将这些功能离子液体用作催化剂，将二氧化碳化学固定为环碳酸盐，并研究了离子液体结构的影响。结果表明，催化剂的 N 原子活性中心、阴离子类型和氢键在 CO2 与环氧化物发生环碳酸盐的环加成反应中起着关键作用。在温和的反应条件下（T = 100 °C，1 atm CO2），离子液体 [DABCO-CH2CH2CH2OH] I 的催化效果最好，具有催化活性高、生态友好、易于加工和方便重复使用等显著优点。
Functional ionic liquids based on DABCO: Efficient catalysts for chemical fixation of CO2 into cyclic carbonates
A series of basic functional ionic liquids were prepared from 1, 4-diazabicyclo [2.2.2] octane (DABCO) with various halogenated hydrocarbons, then these functional ionic liquids were used as catalysts for the chemical fixation of CO2 into cyclic carbonates and the influence of the structure of the ionic liquids was investigated. The results showed that the N atom active center, types of anions and hydrogen bond of the catalyst play a key role in the cycloaddition reaction of CO2 with epoxides to cyclic carbonates. Under mild reaction conditions (T = 100 °C, 1 atm CO2), the ionic liquid [DABCO-CH2CH2CH2OH] I showed the best catalytic effect, which has notable advantages such as high catalytic activity, eco-friendly, ease of work-up and convenient reuse.
期刊介绍：
