摘要

本研究量測離子液體(1-Ethyl-3-methylimidazolium tetrafluoroborate,[Emim][BF4])與九種有機溶劑所組成之二成分混合物的密度與黏度數據。有機溶劑包含二甲基亞碸(dimethyl sulfoxide) 、乙腈(acetonitrile)、甲醇(methanol)、N,N-二甲基甲醯胺(N,N-dimethylformamide)、丁酮(2-butanone)、N -甲基-2 -吡咯烷酮 (N-methyl-2-pyrrolidone)、N,N-二甲基乙醯胺 (N,N-dimethylacetamide)、丙酮(acetone)與乙二醇(ethylene glycol)。量測之溫度為303.15K、313.15K、323.15K與333.15 K，量測之[Emim][BF4]莫耳分率由0.1至0.9。除密度與黏度數據量測外，本研究亦由量測得到之數據，計算離子液體與有機溶劑二成分混合物之過剩莫耳體積(Excess molar volume)與黏度偏差值(Deviation of viscosity)，發現九組二成分混合物系統過剩莫耳體積除乙二醇外皆具有負偏差之行為，且九組混合系統黏度偏差值皆呈現負偏差。此外，亦藉由四參數Redlich-Kister方程式進行過剩莫耳體積與黏度偏差值之數據回歸，並得到滿意之計算結果。

In this study, densities and viscosities data of binary mixture consisted of a room temperature ionic liquid [Emim][BF4] (1-ethyl-3-methylimidazolium tetrafluoroborate) and organic solvent are reported. Nine solvents including dimethyl sulfoxide、acetonitrile、methanol、N,N-dimethylformamide (DMF)、2-butanone (MEK), N-methyl-2-pyrrolidone (NMP)、N,N-dimethylacetamide (DMAC)、acetone and ethylene glycol are considered in our measurement. Density and viscosity data of binary mixture at four temperatures including 303.15 K、313.15 K、323.15 K and 333.15 K. Nine mole fraction of [Emim][BF4] from 0.1 to 0.9 are measured. In addition, excess molar volume and deviation of viscosity are also calculated from our measured data. The results show negative deviation of excess molar volume for all binary mixture except ethylene glycol, and all of our nine binary systems show negative deviation of viscosity for binary mixture. Furthermore, the excess molar volume and deviation of viscosity are correlated using a four parameter Redlich-Kister equation. Satisfactory calculated results are obtained and finally presented in our study.
