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-propanol, 2-methyl 2-propanol and 1-pentanol. The experimental T–x data are correlated using Wilson and NRTL equations for the liquid phase activity coefficients using a non-linear regression approach based on maximum likelihood principle. Excess free energy of mixing, computed from the activity coefficients, is positive in all the systems over the entire range of composition.
