Abstract

The results of studies on the preparation of sodium dihydrogen phosphate monohydrate from simultaneously added mixtures on the basis of EPA from phosphorites of the Central Kyzylkum are presented. The ability to purify oxides, calcium, and fluorine by pre-desulfurized sodium carbonate and metasilicate and washed desalinated barium carbonate with washed calcined phosphorus concentrate by deep desulfurization and ammonization of deep disulfated acid with ammonia gas is shown in p-51.4.

Na2O:P2O5 = 0,41-0,44 or pH 6,2-6,5 the addition of sodium carbonate to a solution of ammonia in the ratio allows to obtain purified solutions of sodium ammonium phosphate.
