Abstract: Using a precision static oxygen-bomb calorimeter, the standard energies of combustion at 298.15 K of tetra-(o-methoxyphenyl)porphyrin and tetra-(p-dimethylaminophenyl) porphyrin were determined to be-32. 7967±0.0122 kJ g~(-1), -34.5011±0.0115 kJ g~(-1) respectively, the corresponding standard enthalpies of formation at 298.15K were calculated to be -205.8±9.0 kJ mol~(-1), -434.8±9.1 kJ mol~(-1).
