在288.15- 333.15K温度范围内，以5 K为温度步长，在常压下测定了吡啶+PEG 200、吡啶+PEG 400、尼古丁+PEG 200和尼古丁+PEG 400四种二元混合物的粘度。根据实验数据计算了所选二元体系的粘度偏差和超额摩尔粘流活化能，并用Redlich-Kister多项式方程进行拟合，并分别用MAGAC-VISCO和ASOG-VISCO模型预测了所选二元体系的动态粘度。四个二元体系的粘度的实验值被用来确定新的相互作用参数，它们的应用在MANUAC-VISCO和ASOG-VISCO模型。粘度数据还与两个参数Teja-Rice和三个和四个参数麦卡利斯特模型相关。(c)2012爱思唯尔有限公司版权所有。
Viscosities of four binary mixtures: pyridine + PEG200, pyridine + PEG400, nicotine + PEG200 and nicotine + PEG400 have been measured in temperature range 288.15-333.15 K with temperature step of 5 K and at the atmospheric pressure. Viscosity deviations and excess molar Gibbs energies of activation of viscous flow for the selected binary systems were calculated from the experimental data and fitted to the Redlich-Kister polynomial equation.In addition, UNIFAC-VISCO and ASOG-VISCO models were used to predict the dynamic viscosities of the investigated binary mixtures. The experimental values of viscosity for the investigated four binary systems were used to determine the new interaction parameters for their application in UNIFAC-VISCO and ASOG-VISCO models. The viscosity data have also been correlated by two parameters Teja-Rice and three and four parameters McAllister models. (c) 2012 Elsevier B.V. All rights reserved.
