text: Phosphoric acid may also be produced in this embodiment and may be recovered or recycled as makeup phosphoric acid.
text: s solution thereof is dissolved in an organic solvent completely miscible with water, the resulting solution is freed from undissolved matter and the phosphoric acid is recovered from the solution.
text: More particularly, the crude acid, commonly prepurified crude acid, is countercurrently contacted in several stages with the solvent, the resulting crude extract is freed from minor proportions of ionic compounds by scrubbing it with water, H 3 PO 4 or a salt solution, and phosphoric acid is ultimately recovered from the pure extract by re-extraction with water or alkaline liquor, or by distillative removal of the solvent.
text: No. 4,321,245, which provides for the sulfate ions to be removed by the addition of barium compounds and countercurrent extraction in several stages in the presence of sulfuric acid with the aid of organic solvents being immiscible or only partially miscible with water, and for the phosphoric acid to be recovered from the separated organic extract.
