Abstract

The aim of this work is the parameters test of the equation of state for hard convex body chain in predicting the critical properties of binary mixtures of n-alkanes. The predicted critical properties agree closely with the experimental results and are better than the predicted values both from the hard convex body equation of state and the Guggenheim equation of state for hard spheres. The agreement between theoretical and experimental results of the critical properties of n-alkanes appears to be improved negligibly, even if the shape of the molecule is considered. However, an improvement in the accuracy of the result is obtained with the equation of state of the hard convex body chain compared to the simple hard convex body equation of state.
