Abstract

The equilibrium research was performed for the NH₄NO₃ + NaVO₃ + NH₄VO₃ + NaNO₃ + H₂O system at 293 and 303 K. The location of the P₁ and P₂ triple points was determined on the equilibrium plots with the planar projection according to Jänecke method. The maximum yield of the conversion of ammonium nitrate(V) to ammonium vanadate(V) was calculated at P₁ points. The results constitute the basis to design further equilibrium experiments aimed to precisely determine the lines separating the areas of the co-crystallization of salts in the investigated system on the equilibrium plots in the oblique projection on a plane according to Jänecke method.
