Abstract
336,008. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). July 10, 1929. Diammonium phosphate solution is mixed with the dry salt, to obtain a moist product which can be dried at a temperature of about 60-80‹ C. without loss of ammonia. The diammonium phosphate solution is preferably made from phosphoric acid, still containing some of the sulphuric acid used to decompose the crude phosphates, which is evaporated to a specific gravity of 1.4-1.5, and cooled, when the contained calcium is precipitated as sulphate and removed. The solution is then neutralized, the precipitated iron and aluminium being left in the solution.
