Isobaric vapour-liquid equilibria of methyl cellosolve-aliphatic alcohol systems

Isobaric vapour-liquid equilibrium data are determined at 40 and 95 kPa for six binary mixtures consisting of methyl cellosolve (2-methoxyethanol) as a common component and aliphatic alcohols as non-common components. The non -common components include ethanol, 1-propanol, 1-butanol, 2-methyl 1-propa nol, 2-methyl 2-propanol and 1-pentanol. The experimental T-x data are corr elated using Wilson and NRTL equations for the liquid phase activity coeffi cients using a non-linear regression approach based on maximum likelihood p rinciple. Excess free energy of mixing, computed from the activity coeffici ents, is positive in all the systems over the entire range of composition. (C) 1999 Elsevier Science B.V. All rights reserved.
