Thermochemistry of nitronaphthalenes and nitroanthracenes

Experimental study on the thermochemistry of 1-(2H)-phthalazinone and phthalhydrazide

“…The equilibrium pressure at this temperature p(T = hTi) and the entropies of sublimation, at equilibrium conditions, are also presented in table 7. where D g cr c p;m was estimated as been 50 J Á K À1 Á mol À1 , a value in accordance with the estimations made by other authors [21], which our Research Group has already used in previous papers for other organic compounds [22][23][24][25][26][27][28]. Table 9 contains for each compound the values of the standard molar enthalpies, entropies and Gibbs energies of sublimation, at T = 298.15 K.…”

Structural studies of cyclic ureas: 3. Enthalpy of formation of barbital

“…The value used for D g cr C p;m was estimated as Àð50 AE 20Þ JÁ mol À1 Á K À1 , in accordance with similar estimations made by Burkinshaw and Mortimer [48], which we have already used in previous papers for other organic compounds [49][50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65][66] The uncertainties assigned to D g cr S m ðT ¼ 298:15 KÞ were obtained considering the uncertainties of D g cr S m ðhTi; hpiÞ and the ones of pðT ¼ hTiÞ from the Clausius-Clapeyron of the global results, presented in table 5. …”

Standard molar enthalpies of formation and of sublimation of 2-thiophenecarboxamide and 2-thiopheneacetamide

“…For each compound studied, the value of D g cr C p;m was estimated as being À50 J AE K À1 AE mol À1 , resembling estimations made by other authors [43], a value that our Research Group has already used for other organic compounds [44][45][46][47][48][49][50]. The standard molar enthalpies, entropies and Gibbs energies of sublimation, at T = 298.15 K, are presented in table 7.…”
