A TG—DSC investigation of the thermal dissociation of selected guanidinium salts

Abstract The TG and DSC curves of guanidinium acetate, carbonate, chloride, chromate, nitrate, sulfate and thiocyanate are reported for the temperature range 25–500°C. Except for guanidinium carbonate, the TG curves were characterized by a single-step mass-loss reaction, involving thermal dissociation and/or vaporization processes. The DSC curves, with the exception of guanidinium chromate, consisted of two or more endothermic peaks, the lowest temperature peak of which corresponded to the fusion of the compound. Exothermic peaks were found only in the DSC curve of guanidinium chromate.
