1、本科畢業(yè)論文（設(shè)計）1-乙基-3-甲基咪唑乳酸鹽離子液體的熱力學(xué)性質(zhì)研究Thestudyonthermodynamicpropertiesof1-ethyl-3-methyimidazoliumlacticacidionicliquidBohaiUniversity1-乙基-3-甲基咪唑乳酸鹽離子液體的熱力學(xué)研究摘要離子液體（ionicliquid）是指在室溫范圍內(nèi)(通常為100℃)呈現(xiàn)液態(tài)的完全由離子構(gòu)成的物質(zhì)體系，又稱室溫離子液體(roomtemperatureionicliquids)。離子液體的最早報導(dǎo)可以追溯到20世紀初。與傳統(tǒng)的溶劑相比離子液
2、體具有如下特點:(1)沒有顯著的蒸氣壓(2)具有良好的溶解能力。(3)具有良好的導(dǎo)電性。(4)具有較好的熱穩(wěn)定性和化學(xué)穩(wěn)定性。(5)易于與其他物質(zhì)分離，可循環(huán)利用。(6)制備簡單。作為新型的綠色溶劑和環(huán)保電解質(zhì)，離子液體其具有良好的導(dǎo)電性、較低的熔點、寬闊的電化學(xué)窗口和可以忽略的蒸汽壓等多種優(yōu)點而廣泛的應(yīng)用于諸多領(lǐng)域。因此，離子液體的合成開發(fā)與應(yīng)用越來越受到化學(xué)工作者的重視，已被廣泛地應(yīng)用于有機合成、分離、電化學(xué)和無機物的制備中。本文對離子液體的類別、特性、發(fā)展歷史及應(yīng)用前景做了總結(jié)，并以1-乙基-3-甲基咪唑乳酸鹽離子液體為研究對象,對離子液體熱力學(xué)性
