Abstract:
The solubility polytherm for the NH4NO3 – NH2C2H4OH · CH3COOH – H2O system was studied using eight internal sections. On the constructed polythermal solubility diagram, the fields of ice crystallization, α, β, γ-modifications of ammonium nitrate, acetic acid, and monoethanolammonium mono-acetic acid are distinguished.On the basis of the data for sections and binary systems, a diagram of the solubility of the ammonium nitrate – monoethanolammonium formic acid – water system was constructed. On the polythermal diagram, solubility, crystallization fields are distinguished: α, β, γ -modifications of ammonium nitrate, monohydrate monohydrate monoethanolammonium formic acid, anhydrous monosubstituted monoethanolammonium formic acid and ice. The studied systems belong to a simple eutonic type, while maintaining the individuality of the constituent components.
