The principle aim of this study was to test the capabilities of Quartic equation of state for describing binary mixture properties. The proper expressions for the derived properties of mixtures were developed based on proper mixing rules. Based on pure component classification of 5 groups, the binary mixtures in this work is 13 groups. The values of the interaction parameter (Kij) were determined. According to this study, the Quartic EOS can be used with % AAD less than 5% for the following binary systems: alcohol & alcohol, water & ketone, water & ester, hydroxy acids & amine, ester & ketone, amine & ketone, alcohol & hydrocarbon, hydrocarbon & hydrocarbon. It is not accurate for the following binary systems : water & acids, alcohol & amine, amine & nitril compound, ester & amine, acid & dichloroethane, aldehyde & dichloroethane, hydrogen sulfide & hydrocarbon, alcohol & dimethyl sulfide, ketone & chlorohydrocarbon, ester & hydrocarbon, nitrohydrocarbon & chlorohydrocarbon. However, accuracy depends on the temperature pressure ranges, Comparative study with Peng-Robinson EOS was also performed
