| Abstract: | A new method for correlating the critical properties of pure substances is proposed in this paper.The data required in the method are: liquid density, Z_(RA)and vaporization enthalpy at normal boiling point.The reliability of the method is discussed on the basis of the estimated P_C and T_C values of nearly 100 representative organic compounds and 16 inorganic compounds. |
