【 摘 要 】

References(11)Cited-By(164)To extend the applicable systems and improve the accuracy of ASOG (Analytical Solution of Groups), which is a predictive method for activity coefficients, the group interaction parameters have been newly determined and some of those reported are revised. The group interaction parameters are increased to 341 group pairs consisting of 43 groups against the previous 31 groups and 138 group pairs. Twelve groups are newly added: pyridine, furfural, ACRY, Cl (C=C), DMSO, NMP, C≡C, SH, DMF, ethanediol, DEG, and sulfolane. The parameters for the previous 31 groups are revised for 10 of those groups: C=C, ArOH, GOH, O, CHO, CON, CN, ArNH2, Cl, and ArCl. The parameters are then extended by providing missing values for others among the 31 previous groups. The temperature range of experimental data used for parameter determination is 293 K to 423 K.
