Abstract
Thermal decompositions of zinc(II) chloroacetate and its complexes wit h nicotinamide and caffeine were studied by means of TG/DTG, DTA, IR a nd mass spectroscopy. Thermal analysis showed that presence of the hal ogen significantly influenced the thermal decomposition. Decomposition s may be characterized as two step reactions (release of nicotinamide or caffeine followed by pyrolysis of the carboxylate anion). Zinc chlo ride, CO, CO2, CH2O, ClCH2CHO were found in gaseous products of the th ermal decomposition.
