Studies on Thermochemistry of Porphyrins III.The Stndard Energies of Combustion and Standard Enthalpies of Formation of Tetranitrophenylporphyrin and Tetrapyridinylporphyrin
Abstract:
Using a precision static oxygen-bomb calorimeter, the standard energies of combustion at 298.15K of tetra-(p-nitrophenyl)-porphyrin, tetra-(3-pyridinyl)porphyrin were determined to be -27.412±0.012, -32.749±0.011 kJg~(-1), and the corresponding standard enthalpies of formation at 298.15 K were calculated to be 751.0±11.0, 811.8±8.6 kJ mol~(-1), respectively. The uncertainties of the results are given as twice of the final over-all standard deviation of the main.
