ABSTRACT
Isothermal (vapor + liquid) equilibrium for the two binary systems (maleic anhydride + di-isobutyl hexahydrophthalate and maleic anhydride + di-n-butyl phthalate) at T = (413.2, 433.2, and 453.2) K were determined using the ebulliometric method. The parameters of the NRTL model for the two binary systems were obtained from the correlation of the experimental data.
