Determination of heats of vaporization and some other thermodynamic quantities for several fluorinated halogen derivatives of ethane and propane

Abstract

Some physico-chemical properties were determined for 1,1,1-trichlorotrifluoroethane, 1,1,2-trichlorotrifluoroethane, 1-bromo-1-chloro-2,2,2-trifluoroethane and 1,2-dichlorohexafluoropropane. For all the substances, their heats of vaporization in dependence on temperature were measured and their densities and refractive indices at two temperatures were determined. For 1,1,1-trichlorotrifluoroethane and 1,2-dichlorohexafluoropropane the saturated vapour pressures were measured, too. The temperature dependences of standard heats of vaporization, vaporization internal energies and cohesive energies were determined on the basis of the experimental data.
