An estimation method for critical properties that is easily available for both organic and inorganic compounds with considerable accuracy is proposed. In this method critical temperature, critical pressure and critical volume can be estimated solely from data of the normal boiling point and the liquid density of pure substance by means of succesive approximations that are repeated until calculated critical pressure (Pc) converges. The average errors of Tc, Pc and Vc for about 24O substances studied were 1.39, 2.61 and 2.OA percent, respectively, but the errors for nitrogen compounds, bromide compounds, metallic elements, and compounds associated in the vapor phase were sometimes larger.
