| Summary: | 碩士 === 國立臺北科技大學 === 生化與生醫工程研究所 === 102 === 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.
