EXCESS MOLAR GIBBS ENERGIES OF 2-METHYLPROPAN-1-OL WITH BENZENE OR TOLUENE OR O-XYLENE OR M-XYLENE AND P-XYLENE AT 308.15K IN TERMS OF AN ASSOCIATION MODEL

Excess molar Gibbs energy values for 2-methylpropan-1-ol + benzene or toluene or o- or m-and p-xylene at 308.15 K have been calculated by Ba rker method from vapour pressure data measured by a static method over the entire range of composition. The excess Gibbs energies for these binary systems are also analysed in terms of the Mecke-Kempter type of association model with a Flory contribution term using two interactio n parameters.
