碩士 === 中國文化大學 === 化學工程與材料工程學系奈米材料碩士班 === 101 === In the general chemical industry, the unit operation device such as extraction columns, filters and packed absorption towers; the technical area such as the synthesis reaction and separation technology, during the transports, program designs and the operations of the processes, many the characteristics of the material physical change and the phenomenon of fluid are still required to do a detailed and accurate calculation of the density and viscosity. These references are the essential elements. This work measures (ethanol + dimethylsulfoxide ), (ethanol +1- methyl-2-pyrrolidinone) and (dimethylsulfoxide+1-methy-2-pyrrolidinone) the three binary system, and (ethanol + dimethylsulfoxide +1-methyl-2- pyrrolidinone) the density and viscosity of the ternary system, under the atmosphere pressure, there are four different temperatures 293.15 K、 298.15 K、 303.15 K、 308.15 K. Density measurement use the oscillating tube density meter to do the measurement, viscosity is measured by the falling ball viscosity. By the experiment, we can calculate the surplus molar volume density and the viscosity deviation, using the Redlich-Kister polynomial equation to estimate the excess of the molar volume and viscosity deviation. If the deviations of the experiment values and predicted values are small, calculated by experiment value is very close. The density value of the binary system is about 0.81 to 1.1 . The viscosity value is about from 0.9 to 2.0 . The standard density deviations are all less than 2 %. The binary system experiments of excess molar volume in this thesis are all negative contributions, the negative contribution values are approximately from 0.05 to 0.8 .And the density value of the ternary system is about between 0.89 to 1.04 . In this study, the ternary system of excess molar volume is negative contributions. Using the datas of ternary system by Tsao-Smith, Jacob-Fitzner, Rastogi, Kohler, Radojkovic, Toop, Colinet, Scatchard , Vm2+13 and Pseudo-binary mixture approach (PBMA) those empirical equations to predict the outcomes. And the equation outcomes of Rastogi, Vm2+13 and Pseudo-binary mixture approach (PBMA) are the best results.
