摘要：

A new method for calculating the critical pressure values from liquid density (or molar volume) data and vaporization heat data at normal boiling point is proposed in this paper. The reliability of the method is discussed on the basis of the results obtained by predicting the P-c and T-c values of nearly 100 organic compounds which are representative of many structural types including some strongly associated molecules such as alcohols.
