VAPOR-LIQUID-EQUILIBRIA IN MIXTURES OF METHANOL, METHYL ACETATE AND VINYL-ACETATE

Isobaric vapor-liquid equilibria were determined for the binary system s methanol-vinyl acetate and methyl acetate-vinyl acetate in a recircu lation still at atmospheric pressure. A minimum boiling azeotrope was observed in the methanol-vinyl acetate system. Thermodynamic analysis of the experimental data was carried out by considering criteria given by Kollar-Hunek et at (1986). All data were reduced to the parameters in the equation given by Wilson (1964), Renon and Prausnitz (1968), r espectively by Gothard (1985), using a new version of maximum likeliho od procedure given by Panaitescu (1982).
