Thermodynamics Properties of Fluorochloromethanes and –Ethanes

Abstract

A\ curate data on the liquid density of a compound are a necessary prerequisite to the calculation of its thermodynamic properties. This paper covers in detail the results obtained in the measurement of the liquid densities of CHC1F2, CHC12F, CCI3F, and CC12F-CC1F2. It also includes the data obtained in the determination of the rectilinear diameters and critical constants of the four compounds.

Physical and thermodynamic properties of trifluoromethane

“…The saturated liquid density of trifluoromethane was determined from 370" to 538"R. by the method describcd by Benning and McHarness (4). The technique employed in the measurement mas to find the temperature a t which the dcnsity of the saturated liquid matched that of a precalibrated density float.…”
