The objective of this study was to investigate the physicochemical interactions between calcium chlorate and triethanolammonium monochloroacetate in aqueous systems and to determine their phase behaviour. The ternary system Ca(ClO3)2 - (C2H4OH)3N·ClCH2COOH - H2O was studied using the visual-polythermal method combined with physicochemical analytical techniques. A polythermal solubility diagram of the system was constructed over the temperature range from -52°C to 47°C. The analysis revealed the crystallization fields of ice, Ca(ClO3)3 hydrates (Ca(ClO3)2·6H2O, Ca(ClO3)2·4H2O and Ca(ClO3)2·2H2O), triethanolammonium monochloroacetate, and a newly formed crystalline compound with the composition ClCH2COOH·Ca(ClO3)2·(C2H4OH)3N. The formation and individuality of the new compound were confirmed by chemical analysis, IR spectroscopy and scanning electron microscopy. The obtained results provide a physicochemical basis for improving chlorate-based defoliant formulations and optimizing their production technologies.
