Description
фосфорной кислотой. Юг приведенного выше состава фосфорита помещают в сосуд Дьюара, в который был залит 50 мл жидкого азота и обрабатывают перемешиванием до полного израсходовани последнего. Далее в сосуд наливают экстракционную фосфорную кислоту (25,4% Р2О5) из расчета получени в результате разложени монокальций фосфата. Норма фосфорной кислоты 95% против стехиометрического количества.phosphoric acid. The south of the above phosphorite composition is placed in a Dewar vessel, into which 50 ml of liquid nitrogen was poured and treated by stirring until the latter is completely consumed. Next, extraction phosphoric acid (25.4% of P2O5) is poured into the vessel at the rate of obtaining monocalcium phosphate as a result of decomposition. The rate of phosphoric acid is 95% versus stoichiometric amount.
Разложение провод т при 85-90°С в течение 1 час. Затем реакционную массу нейтрализуют газообразным аммиаком и высушивают при 80-90°С. Коэффициент извлечени PjOs в усво емую форму составл ет 95%.Decomposition is carried out at 85-90 ° C for 1 hour. Then the reaction mass is neutralized with gaseous ammonia and dried at 80-90 ° C. The recovery rate of PjOs in digestible form is 95%.
