Abstract

The thermal stability of the food additives Na metabisulphite, Na and K acetates, glutamic and citric acids, respective of the pharmaceuticals nifedipine and acetyl salicylic acid was studied by means of the non-isothermal kinetic (Friedman differential method). The specificity of the thermal decomposition was characterized by identification of the bond to be selective activated due to energy absorption at vibrational level. These bonds were assigned by comparison of calculated wave numbers with the wave number of the IR spectra.
