Abstract

The Martin equation of state may be applied to a polar substance provided that the equation parameter a is made to fit the vapor pressure data at the temperature of interest. Instead of Martin's procedure for adjusting parameters b and c by means of the value of the experimental critical compressibility factor, it is best to use with a polar compound a liquid density datum point as close to the temperature of interest as possible and to obtain values of b and c by volume translation. This procedure is illustrated with the ethylene-chloroform system. Other high-pressure systems studied are the ethane-acetone system, the hydrogen sulfide-water system, and the carbon di-oxide-methanol system. Some of the results are compared with those obtained by Guo and co-workers with the cubic chain-of-rotators equation. © 1987, American Chemical Society. All rights reserved.
