Standard molar enthalpies of formation of some trichloroanilines by rotating-bomb calorimetry

摘要: Abstract The standard ( p o  =  0.1 MPa) molar enthalpies of formation Δ f H m , at the temperature 298.15 K, for crystalline 2,3,4-, 2,4,5-, 2,4,6- and 3,4,5-trichloroaniline were derived from combustion c in oxygen using rotating bomb calorimetry. reaction products CO 2 (g) N HCl · 600H O(l) . sublimation cr g T K measured by Calvet microcalorimetry. results are as follows: gaseous compounds compared with values estimated assuming enthalpy increment substitution chlorine aniline to be same into benzene.
