1、本科毕业论文（设计）1-乙基-3-甲基咪唑乳酸盐离子液体的热力学性质研究Thestudyonthermodynamicpropertiesof1-ethyl-3-methyimidazoliumlacticacidionicliquidBohaiUniversity摘要离子液体（ionicliquid）是指在室温范围内(通常为100℃)呈现液态的完全由离子构成的物质体系，又称室温离子液体(roomtemperatureionicliquids)。离子液体的最早报导可以追溯到20世纪初。与传统的溶剂相比离子液体具有如下特点:(1)没有显著的蒸气压(

2、2)具有良好的溶解能力。(3)具有良好的导电性。(4)具有较好的热稳定性和化学稳定性。(5)易于与其他物质分离，可循环利用。(6)制备简单。作为新型的绿色溶剂和环保电解质，离子液体其具有良好的导电性、较低的熔点、宽阔的电化学窗口和可以忽略的蒸汽压等多种优点而广泛的应用于诸多领域。因此，离子液体的合成开发与应用越来越受到化学工作者的重视，已被广泛地应用于有机合成、分离、电化学和无机物的制备中。本文对离子液体的类别、特性、发展历史及应用前景做了总结，并以1-乙基-3-甲基咪唑乳酸盐离子液体为研究对象,对离子液体热力学性质进行研究。关键词:离子液体;绿
