PHYSICO-CHEMICAL PROPERTIES OF DESULFATED PHOSPHORIC ACID FROM PHOSPHORITES OF CENTRAL KYZLKUM

Abstract

There results of laboratory researches on desulfuration of weak wet-process phosphoric acid by calcareous phosphorite powder subsequent it concentration using evaporation were stated. There were determined the composition both the desulfuration and the evaporated solution phosphoric acid. The rate distribution of components on liquid and solid phases was calculated. It was studied that rheological properties (density, viscosity), steam tension and boiling temperature of evaporated and desulfurated wet-process phosphoric acid.
