A Simple Equation for Predicting the Volumetric Properties of Mixtures Involving Ionic Liquids

A simple equation has been employed to predict the volumetric properties of binary mixtures involving an ionic liquid. Moreover, we have calculated excess volumetric properties of the studied mixtures using the proposed equation. The outcomes of our computations have been compared with experimental data. The reliability of the proposed model was checked by taking 854 experimental data points over a temperature range from 278 to 358 K; the average absolute deviation of the calculated density and the excess molar volume were found to be 0.50 and 0.80 %, respectively, while the accuracies of our calculations were of the order of ±3 %.
