Vapour–Liquid Equilibria in the Poly(methyl methacrylate) + + 2-Butanone System Containing Lower Concentrations of Solute at Normal or Reduced Pressures

Vapour-liquid equilibria (VLE) were determined in the poly(methyl methacrylate) + 2-butanone system under isothermal conditions at 333.15, 343.15, and 353.15 K using an improved all-glass micro-ebulliometer with circulation of the liquid phase for the dynamic measurement of total pressure over liqui...

description Vapour-liquid equilibria (VLE) were determined in the poly(methyl methacrylate) + 2-butanone system under isothermal conditions at 333.15, 343.15, and 353.15 K using an improved all-glass micro-ebulliometer with circulation of the liquid phase for the dynamic measurement of total pressure over liquid mixtures. The experimental data were correlated using the UNIQUAC-FV model and the applicability of three known predictive models was tested. It was found that only the UNIFAC-vdw-FV model gives excellent prediction of VLE for the studied system. Key words: vapour-liquid equilibrium, experimental data, polymer-solvent system, correlation, ebulliometer
