碩士 === 國立臺灣科技大學 === 化學工程系 === 104 === A novel ionic liquid [TBP][TAPS] derived from basic hydroxide solution tetra-n-butylphosponium ([TBP][OH], 40 wt% in H2O) and Good’s biological buffer n-[tris(hydroxymethyl)]-3-amino-propanesulfonic acid has been synthesized by simple acid-base neutralization method. The physical properties, including density, thermal expansion, apparent molar volume, viscosity, conductivity, and molar conductivity have been determined for the binary ionic solutions of [TBP][TAPS] with water, methanol, ethanol, 1-propanol, 2-propanol, or tert-butanol at temperatures from 283.15 K to 333.15 K under atmospheric pressure. Several correlative equations were used to fit the physical properties data. These models include a polynomial equation for density, the Vogel-Fulcher-Tammann equation for viscosity, and the Casteel-Amis equation for conductivity. The correlated results are satisfactory.
