  Abstract:  An extrapolation of the van der Waals equation of state to the liquid phase by considering the total internal pressure and the dependence of the constants “a” and “b” on temperature and density is made. The validity of the state equation was checked by comparing the values of the ultrasound propagation velocities calculated by these equations to the experimental ones. Based on the state equations the total potential energy of intermolecular interactions, that of dispersion and that of rejection were estimated at different temperatures. The studied liquids were: benzene and carbon tetrachloride in the range 20 – 700 C, acetone and chloroform in the range 20 – 500C and carbon disulphide in the range 20 – 400C.
