| Abstract: | A sublimation calorimeter has been constructed in our laboratory for solid compounds in pressure range≥0.1 mmHg at 298.15 K. Using this calorimeter and LKB 8700 vaporization calorimeter, the enthalpies of vaporization, ΔH, or the enthalpies of sublimation, ΔH_(sub), of trichorohenzens were measured to be; Compound ΔH(kJmol)~(-1) ΔH_(sub)(kJmol~(-1)) Water 43.72±0.18 n-Decane 51.21±0.25 Naphthalene 73.26±0.92 1,2,3-Trichlorobenzene 75.14±0.75 1,2,4-Trichlorobenzene 55.06±0.50 1,3,5-Trichlorobenzene 72.68±0.50 |
