THE PRESSURE-VOLUME-TEMPERATURE PROPERTIES OF PERFLUOROCYCLOBUTANE:EQUATIONS OF STATE, VIRIAL COEFFICIENTS, AND INTERMOLECULAR POTENTIAL ENERGY FUNCTIONS

摘要

Studies of the pressure-volume-temperature properties of perfluoro-cyclobutane in the ranges, 3-394 arm., 30-350°, yielded values of gas Compressibility, critical constants, vapor pressure and orthobarlc liquid and vapor densities. The results were correlated by the Beattie-Bridge man, Benedict-Webb-Rubin, and Martin-Hoe equations of state, and by the Stockmayer and the Klhara intermolecular potential energy functions. The merits of the several correlational methods are discussed.
