The parameters of the intermolecular interaction potential of 2,2-dimethylpropane are obtained. Determination of the parameters was performed by Zeno line. It was shown that the quaternary carbon atom makes a minor contribution to the intermolecular interaction. However, variations of the potential parameters of this interaction center can more accurately predict the thermodynamic properties. The resulting model of intermolecular interactions showed a good description of PVT properties of the single-phase region and the properties on the phase equilibrium line.
