Polytherm of Solubility of System Mg(ClO₃)₂–[21% ClCH₂CH₂PO(OH)₂^.NH₃ + 11% ClCH₂CH₂PO(OH)₂^.2NH₃ + 12% NH₄H₂PO₄ + 56% Н₂О]–H₂O

Solubility in the section of a complex aqueous system consisting of chloroethylphosphonates, ammonium phosphate, and magnesium chlorate was studied in the temperature range from –66.8 to 12.4°C. A polythermal phase diagram was constructed, on which the crystallization fields of ice, hexa-, tetra-, and bihydrate magnesium chlorate, and drug “Nazhot” were delimited. The composition of the latter was [21% ClCH₂CH₂PO(OH)₂⋅NH₃ + 11% ClCH₂CH₂PO(OH)₂⋅2NH₃ + 12% NH₄H₂PO₄ + 56% H₂O]. In addition, crystallization fields of compound chloroethylphosphonate ammonium monochlorate NH₄CIO₃⋅CICH₂CH₂HPO₃NH₄ was also determined. The composition of the latter compound was confirmed by chemical and physicochemical analyses.
