Solubilities of isobutene in methanol plus benzene, methanol plus cyclohexane and benzene plus cyclohexane mixed solvent solutions at 298 K and 27-102 kPa

摘要

The solubilities of isobutene at pressures from 27 to 102 kPa and a temperature of 298.15 K are presented for three mixed solvent solutions: methanol + benzene, methanol + cyclohexane and benzene + cyclohexane. The measured isobutene solubilities are within 5% of being ideal solubilities for methanol + benzene mixtures, within 9% for benzene + cyclohexane mixtures and within 20% for methanol + cyclohexane mixtures, there is a qualitative similarity between the excess volumes and excess solubilities. Henry's constants of isobutene in these solvent solutions are evaluated by two different methods. (C) 2002 Elsevier Science B.V. All rights reserved. [References: 9]
