Based on Pitzer correlations for the compressibility factor and virial equation of state, a new equation of state has been developed by authors, which is a function of total number of atomspresent in the solute molecule, normal boiling point temperature and reduced temperature. Peng- Robinson EOS, together with two adjustable parameter Van der Waals mixing rules, and the proposed EOS are used for correlation of 60 drugs solubility in this paper. As the results show, theproposed EOS presents more accurate predictions for solubility data in Supercritical CarbonDioxide. So it can be employed to accelerate the industrial processes
