A method is presented to determine thermodynamic and kinetic parameters from complex thermoanalytical curves. Such curves are obtained when thermoanalytical events like phase transisition and chemical decomposition overlap. Isoprophylammonium nitrate was taken as an example to demonstrate how these parameters were determined from non-isotherm TG and DSC curves by constructing DSC-DTG sum curves.
