Vapor-Liquid equilibria for Binary Mixture with Anisole

Reich, Ricardo; Sanhueza, Vilma

Keywords: binary, equilibria, mixture


Vapor-liquid equilibrium (VLE) data have been measured for binary mixtures of anisole (methyl phenyl ether) with paraffins, olefins, alcohols, benzene and methyl ethyl ketone. A total of nine systems was investigated in the temperature range 328–368 K and pressures below atmospheric. The data were reduced using Barker's method, and they were found to be thermodynamically consistent. VLE predictions by means of the UNIFAC model using the‘CH2O’ ether group render, in general, poor results when applied to mixtures containing aromatic ethers. In this work, the VLE data available for these systems, were correlated by means of a maximum likelihood procedure in order to obtain the UNIFAC interaction parameters for a new ‘ACOCH2’ aromatic ether group.
