Abstract
A description of the Stirling thermochemical laboratory is given along with details of the macro aneriod rotating-bomb calorimeter. A convenient analytical procedure has been established to ascertain the final state present in the calorimeter after the combustion of organosulphur compounds. The standard enthalpy of combustion of 1,3,5,7-tetramethyl-2,4,6,8-tetrathiaadamantane has been measured. The value ΔHco(C10H16S4,c) = −(2026.1 ± 0.6) kcalth mol−1 yields a standard enthalpy of formation ΔHfo(C10H16S4,c) = −(36.8 ± 0.7) kcalth mol−1. The standard enthalpy of sublimation has been measured as ΔHsubo(C10H16S4,c, 298.15 K) = (28.0 ± 1.0) kcalth mol−1. The corresponding gas-phase enthalpy of formation is ΔHto(C10H16S4,g) = −(8.8 ± 1.2) kcalth mol−1. The thermodynamic properties of 1,3,5,7-tetramethyl-2,4,6,8-tetrathiaadamantane at 298.15 K have been calculated.
