| Abstract: | Vapour pressures as a function of temperature for 1,3,5-trichlorobenzene CA 108-70-3] (crystalline and liquid), 1,2,4,5-tetrachlorobenzene CA 95-94-3] (crystalline), and 1,2,4,5-tetramethylbenzene CA 95-93-2] (crystalline and liquid) were determined by means of a diaphragm manometer and simultaneous torsion, mass-loss effusion. An unconventional but simple method is used for the representation and the assessment of the present experimental results, together with results from other authors. The method is physical in nature, and at the same time reveals the quality of the experimental results in terms of random and systematic errors. The thermodynamic properties at po = 1 Pa were evaluated, the results being (the uncertainties are standard deviations, and Ttdenotes triple point): |
