Isothermal Vapor Liquid Equilibrium for 2-Methylpropene + Methanol, + 1-Propanol, + 2-Propanol, + 2-Butanol, and + 2-Methyl-2-propanol Binary Systems at 364.5 K

Vapor−liquid equilibrium data were measured using an automatic static total pressure apparatus for binary mixtures
of 2-methylpropene + methanol, + 1-propanol, + 2-propanol, + 2-butanol, and + 2-methyl-2-propanol at 364.5
K. The measured p, T, z data were fitted against Legendre polynomials and reduced using Barker's method to
obtain phase equilibrium data. In addition to Legendre polynomials, binary interaction parameters were also
optimized for Wilson, UNIQUAC, and NRTL activity coefficient models. All binary data showed a positive
deviation from the Raoult's law. In addition, azeotropic behavior was observed for the 2-methylpropene + methanol
binary mixture.
