Method of preparation of a crystalline ammonium dihydrogen phosphate

摘要

P the invention relates to a process for preparing the crystalline ammonium dihydrogen phosphate. / p & & p & the process of the invention is characterized in that it comprises the following steps: a. the addition of a sequestering agent in an aqueous solution of ammonium dihydrogen phosphate; b. heat treatment of said aqueous solution at a temperature of 70°C. or more after the addition of the sequestering agent; and c. crystallization of the ammonium dihydrogen phosphate, on the basis of said aqueous solution after said heat treatment. / p & & p & ammonium dihydrogenphosphate thus obtained can be used, inter alia, as starting material for the manufacture of yeasts, food additives or decolorization agents. / p
