Determination of new ASOG parameters.

Thermodynamics of fluid‐phase equilibria for standard chemical engineering operations

“…To use this correlation, we need temperature-dependent group-group parameters; because Deal and Derr provided only a few of these parameters, the usefulness of ASOG was severely limited. At present, its usefulness is somewhat larger thanks to a monograph (Kojima and Tochigi, 1979) and articles by Tochigi et al (1990Tochigi et al ( , 1998.…”

Prediction of Kinematic Viscosities for Binary and Ternary Liquid Mixtures with an ASOG-VISCO Group Contribution Method

“…In this work, ∆G E was evaluated from the ASOG group contribution method, that is, a predictive method for the activity coefficient γ i , given by the following equations [7]:…”

“…This paper proposes a group contribution method called ASOG-VISCO that combines the Eyring's model with the ASOG group contribution model [7]. By using ASOG-VISCO, the mixture kinematic viscosity can be evaluated from the known viscosity data of pure components and group pair parameters.…”

Isobaric (vapour + liquid) equilibrium of (1,3-dioxolane, or 1,4-dioxane+ 1-butanol, or 2-butanol) at 40.0 kPa and 101.3 kPa

“…We have used the group contribution methods ASOG (20) and UNIFAC (21) to predict vapour-liquid equilibrium. Parameters used are presented in …”
