Thermodynamic Properties of Aliphatic Halogen Compounds: Part 1.—Vapour Pressure and Critical Properties of 1,1,1-Trichloroethane

Abstract

The vapour pressure of 1,1,1-trichloroethane was measured in the range 15 to 200 kPa by comparative ebulliometry, and the critical temperature and pressure were also measured. The observed values of the vapour pressure were fitted by equations, and one of them, a fourth order Chebyshev polynomial, is recommended for use if interpolation between 200 kPa and the critical pressure is required.
