Determination of ASOG Parameters—Extension and Revision

抄録

ASOG is one of the group contribution methods for predicting activity coefficients. This article deals with the determination of ASOG group interaction parameters for 20 group pairs in order to extend and revise the existing parameter matrix. Especially all group interaction parameters relating to the NMP group have been revised and extended. The group interaction parameters relating to the C ≡ C (C-C triple bond group) have been also revised. The data base used for determining the parameters are the vapor-liquid equilibria (VLE) and infinite-dilution activity coefficients ( γ^∞ ) stored in the Dortmund Data Bank.
