The pyrolysis of Fe-tetraphenylporphyrin chloride (FeClTPP) has been examined by FTIR spectroscopy.Two series of samples, with and without additional carbon black, were studied.It was found that the decomposition of FeClTPP occured in a very narrow range of temperature.The mixture of FeClTPP and carbon decomposed at a lower temperature than pure crystalline FeClTPP.The oxygen chemically adsorbed on the surface of carbon black may play an important role in this respect.The mechanism of pyrolysis have been discussed and a model of three steps of decomposition was proposed.The first step has been followed also by measuring the chlorine content by means of quantitative XPS.
