Investigation of mutual solubility in the NH4VO3−NH4NO3−H2O system / Mieczyslaw Trypuc in Industrial & engineering chemistry research, Vol. 48 N° 10 (Mai 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 10 (Mai 2009) . - pp. 5058–5063 Titre : Investigation of mutual solubility in the NH4VO3−NH4NO3−H2O system Type de document : texte imprimé Auteurs : Mieczyslaw Trypuc, Auteur ; Sebastian Druzynski, Auteur Année de publication : 2009 Article en page(s) : pp. 5058–5063 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Ammonium  vanadate  Ammonium  nitrate  NH4VO3−NH4NO3−H2O  system  Isothermal  saturation  method Résumé : The solubilities of ammonium vanadate and ammonium nitrate in the NH4VO3−NH4NO3−H2O system were investigated at 293, 303, 313, and 323 K by the method of isothermal saturation of solutions. A section of the solubility isotherm for the investigated system was plotted based on the obtained data. Knowledge of that dependence is necessary for developing the new method of using the postfiltration liquor from the soda−chlorine−saltpeter (SCS) method of sodium carbonate production, based on an equilibrium plot for the quaternary system of pairs of the exchange salts NH4NO3−NaVO3−H2O.

Phase diagram for the NH4NO3 + NaVO3 + NH4VO3 + NaNO3 + H2O System at 293 and 303 K / Mieczyslaw Trypuc in Industrial & engineering chemistry research, Vol. 48 N° 15 (Août 2009)

Based on these isotherms, the maximum yields have been determined for the conversion of ammonium nitrate to ammonium meta-vanadate. The location of the triple points P1 and P2 has been determined on the equilibrium plots prepared as the planar projection, according to the Jänecke method. The results are necessary for determining the optimal conditions for utilization of post-filtration lye obtained from the soda−chloride−saltpeter (SCS) method of soda ash production.

The data obtained were used for plotting the section of the solubility polytherm for the system investigated. Knowledge of the course of the solubility polytherm is necessary for developing a new method of utilization of the post-filtration lye from the soda−chlorine−saltpeter method (SCS) of soda production.
