DESCRIPTION OF VAPOR-LIQUID-EQUILIBRIA OF SOME BINARY-MIXTURES WITH COMPOUNDS CONTAINING OXYGEN

The new local composition model for excess Gibbs energy (NRTLmKW) has been applied for vapour-liquid equilibria in six binary mixtures with compounds containing oxygen: tert-amyl methyl ether + 2,2,4-trimethylp entane, tert-amyl methyl ether + methylcyclohexane, tert-amyl methyl e ther + toluene, 2-ethoxyethanol + methanol, 2-ethoxyethanol + n-valera ldehyde, 2-ethoxyethanol + dipropyl ether. The obtained results prove the superiority of the proposed model over Redlich-Kister, Wilson, UNI QUAC, NRTL, AEOS and PRSV models. Recommendation for a global thermody namic description of associating mixtures by this model is given.
