Abstract
A modification of the process of the parent Specification is characterized in that equimolecular quantities of phosphoric acid and potassium chloride are introduced into a solution saturated with monopotassium phosphate and the acid salt KH2PO4.H3PO4, and that the solution is boiled to expel hydrochloric acid, the content of water being maintained constant by adding water or steam, then cooled, and the mother-liquor separated from the precipitated monopotassium phosphate is employed for further decompositions. Thus, the process may be worked continuously. The separated product may be washed with water, and the wash liquors added to the phosphoric acid-potassium chloride mixture, or, preferably, used to dilute sulphuric acid in the production of phosphoric acid. The process may be effected in revolving or trough furnaces, the reaction mixture being thoroughly stirred.
