The standard ( pΒ°= 0.1 MPa) molar enthalpy of formation for liquid 2,4,6-trimethylpyridine was derived from the standard molar enthalpy of combustion, measured by static bomb combustion calorimetry in oxygen, at the temperature T = 298.15 K: DfH Β°m = -(31.0 2 2.3) kJβ’mol -1 .
The molar enthalpies of solution of UTeO 5 , UTe 3 O 9 , TeO 2 , and UO 3 in HCl (aq, c = 11 mol β’ dm -3 ) have been measured by using an isoperibol calorimeter. From these results and other auxiliary data, the standard molar enthalpies of formation f H o m (298.15 K) of UTeO 5 (cr) and UTe 3 O 9 (c
The derived standard molar enthalpies of formation in the gaseous state are shown to fit a group additivity scheme.
