✦ Synopsis

Excess molar volumes V E m have been determined for (formic acid + benzene, or toluene, or p-xylene) at T = (298.15 and 308.15) K. The aromatic hydrocarbons form two liquid phases with formic acid over different ranges of composition. The value of V E m is positive for all the mixtures and varies as benzene > toluene > p-xylene. The derivative dV E m /dT is also positive.

## Abstract In our earlier work, we have demonstrated that it is possible to characterize binary mixtures using single component descriptors by applying various mixing rules. We also showed that these methods were successful in building predictive QSPR models to study various mixture properties of

It has long been known that the molar refractions of solutions, Rn = {(n 2 -1)/(n 2 + 2}nVm, can be estimated from those of the separated components using additivity relations, but deviations from such rules have been large enough to prevent practical application (such as the calculation of excess v
