โฆ Synopsis
With some exceptions, the densities of compressed liquids can be correlated accurately by a three-constant system of corresponding states. This method is based on the linearity of the unit-compressibility line, and the constancy of the ratio of the deviations from unit compressibility of two different liquids at equal reduced temperatures and densities. Each set of experimental measurements taken from the fiterature is characterized by a Boyle temperature, a unit-compressibility density, and a relative Boyle volume. In many cases the density of one liquid as a function of temperature and pressure can then be calculated within the reported experimental error from P VT measurements on another liquid.

Hankinson and Thomson (1979) developed a correlation for saturated densities of liquids and their mixtures, which overcame mathematical discontinuity (Yen and Woods, 1966;Gunn and Yamada, 1971) and pure compound limiting problems (Spencer and Danner, 1972) in the equations used. In addition, the
An equation of state is presented for compressed liquids at densities between 2 and 3 times the critical density. The equation requires only three characteristic constants for each liquid, and reproduces experimental PVT data for several liquids with an average deviation of less than O" I% in the de
