Three cubic equations of state are utilized in regressing a large vapour‐liquid equilibrium data bank using single and multiple binary interaction parameters. A second binary interaction parameter is shown to be both physically significant and useful in improving the match of experimental data, particularly in polar systems. The use of a third binary interaction parameter in the Trebble‐Bishnoi equation of state is found to be of value in systems with large molecular size differences.
