摘要
本文提出了一个由液体比容和正常沸点下汽化热数据推算物质临界参数的新方法.采用本文方法对有代表性的近100种有机物的 P_c 和 T_c 值进行了估算.计算结果表明,本文方法稳定、可靠.
A new method for calculating the critical constants from the data of liquid density and vaporization heat at normal boiling point is presented in this paper,The method is discussed on the base of the results obtained by esti- mating the Pc and Tc values of nearly 100 kinds of representative organic matters and shows its reliability and stability.
