Thermochemical study of adducts of tetramethylurea with zinc, cadmium, and mercury halides

Solid-liquid equilibria in the reciprocal ternary system potassium, lithium/sulfide, carbonate

“…of the adducts showed that most of them decompose on heating. To evaluate the relative strengths of arsenic-nitrogen bonds, it was necessary to assume that the molar enthalpy of sublimation of each adduct was equal to the enthalpy of vaporization of 1 mol of ligand (34,35). Standard enthalpies of sublimation of several adducts (that could be measured) and its respective ligands, confirmed our assumption (36)(37)(38).…”

Adducts of arsenic trihalides with heterocyclic amines: synthesis, characterization, and thermochemistry

“…The melting point and the thermogravimetry studies of the adducts showed that most of them decompose on heating. To evaluate the relative strengths of arsenic-nitrogen bonds, it was necessary to assume that the molar enthalpy of sublimation of each adduct was equal to the enthalpy of vaporization of 1 mol of ligand (34,35). Standard enthalpies of sublimation of several adducts (that could be measured) and its respective ligands, confirmed our assumption (36)(37)(38).…”

“…can be used to calculate the standard enthalpy of the arsenic-nitrogen bond (D(As-N) = ArHe(g)/n) if the values of the standard enthalpy of sublimation of each adduct is known (30, [33][34][35]. The melting point and the thermogravimetry studies of the adducts showed that most of them decompose on heating.…”

Si–Zr–C–N-based hydrophobic plasma polymer membranes for small gas molecule separation

“…According to the literature [22,23], the two peaks observed at 0.282 and 0.021 ppm were assigned to the CH 3 groups of Zr-N(Si(CH 3 ) 3 ) 2 . The peak at 1.373 ppm was attributed to the protons of CH 3 linked to Zr.…”
