Abstract

The standard enthalpies of formation of ammonium picrate, picric acid, 2,4-dinitrophenol, 2,6-dinitrophenol and methylurea have been determined by oxygen static bomb calorimetry as [diagrams] From solution calorimetry, standard enthalpies of formation have been found for the potassium, rubidium, caesium, silver, tetramethy-lamraonium and tetraetbylaramonium salts of picric acid. [diagram] be 0.26nm.Lattice energies for picrate salts have been calculated. The solubilities of these picrates in water have been determined as a function of temperature. Enthalpies of solution derived from the solubility data have been compared with calorimetric enthalpies of solution. The standard enthalpy of formation of guanidine chloride, CH6N3Cl(c), has been determined as -366.71+4.00 kJ mol -1 using solution calorimetry. Tentative values for the thermochemical radii of the 2,4- and 2,6-dinitrophenolate ions have been assigned. Lattice energies for some salts of these substituted phenols have been calculated. Differential scanning calorimetric and thermogravimetric techniques have been used in an attempt to evaluate kinetic parameters for the decomposition of certain picrates.
