碩士 === 國立臺北科技大學 === 化學工程研究所 === 96 === In this study, PVT data have been measured for five binary systems mixtures composed of anisole, 2-propanol, 2-butanol, 2-pentanol, 2-hexanol, and 2-heptanol with a high-pressure densimeter in a temperature range of 323.15 K to 373.15 K and at pressures up tp 35 MPa. The influence of densities and excess volumes with composition, temperature, and pressure were investigated. The Tait model can correlate accurately the experimental density data over the entire pressure range at fixed composition and temperture. The experimental density data were used to calculate the excess volumes.The excess volumes are positive for Anisole + 2- Propanol ,Anisole + 2- Pentanol ,Anisole + 2- Hexanol and Anisole + 2- Heptanol mixtures,and negative for Anisole + 2- Butanol mixture , and The variation of excess volumes with composition can be represented by the Redlich-Kister model. The SRK,PR and PT cubic equation of state were also employed to correlate the PVT data, and the binary interaction parameters were determined by fitting the binary PVT data to equations of state.The PT equation of state is overall the best.
