• 中文摘要： 本研究將Eyring模式中的過剩流動自由能以混合物的Gibbs自由能乘上一比率因子而求得,其中的過剩Gibbs自由能係利用雙成分交互作用參數設定為零的Patel-Teja狀態方程式估算。研究發現對於非水溶液系統,比率因子可視為常數; 對於水溶液系統(或強氫鍵效應的系統),該比率因子可考慮為組成的線性函數。此法用於多種非水溶液與水溶液混合物黏度的關聯,已獲致肯定的結果。研究中也發現這些模式參數可利用有限的混合物黏度數據來估算,對於一非水溶液系統僅需一個數據點,對於一水溶液系統僅需兩個數據點。
• 英文摘要： The excess activation free energy of flow as defined in the Eyring model was calculated from the excess Gibbs free energy of mixture multiplied by a proportionality factor, in which the excess Gibbs free energy of mixture was estimated from the Patel-Teja equation of state with zero binary interaction constant. It was found that the proportionality factor could be treated as a constant for a nonaqueous system, whereas the factor was considered as a linear composition-dependent (LCD) function for an aqueous system (or a strongly hydrogen-bonded system). Promising results have been obtained from the proposed method to correlate viscosity data for a wide variety of nonaqueous and aqueous mixtures. These model parameters could be estimated from a limited knowledge of mixture viscosity data; one point for a nonaqueous system and two data points for an aqueous system.
