Description
Пример 2. Фосфорную кислоту экстрагируют 75% ТБФ в керосине. Экстракт содержит (в г/л): НзРО4 57,1; НС1 10,2; СаСЬ 14,8. Экстракт промывают оборотным раствором моноаммонийфосфата, содержащим (в г/л): РгОб 137,0; CI 31,5; NHg 47,8, с рН 4,3 в две стадии при объемном соотношении фаз Vo: . Промытый экстракт содержит (в г/л): НзРО4 51,9; НС1 4,76; СаСЬ 0,8.Example 2. Phosphoric acid is extracted with 75% TBP in kerosene. The extract contains (in g / l): NzRO4 57.1; HC1 10.2; COS 14.8. The extract is washed with a working solution of monoammonium phosphate containing (in g / l): PrOb 137.0; CI 31.5; NHg 47.8, with a pH of 4.3 in two stages with a volume ratio of the phases Vo :. The washed extract contains (in g / l): NzRO4 51.9; HC1 4.76; CAC 0,8.
Аммонизацией промытого экстракта получают кристаллический моноаммонийфосфат, содержащий (в вес. %): PaOs 59,6; СаО 0,35; N2 11,9. Содержание НС1 и СаС уменьшаетс на 74 и 94,5% соответственно.Ammonization of the washed extract gives crystalline monoammonium phosphate containing (in wt.%): PaOs 59.6; CaO 0.35; N2 11.9. The content of HC1 and CaC decreases by 74 and 94.5%, respectively.
Следовательно, обработка экстракта сол ми фосфорной кислоты приводит к увеличениюTherefore, the treatment of the extract with phosphoric acid salts leads to an increase in
содержани фосфорной кислоты в экстракте и очистке от соэкстрагируемых минеральных кислот и солей.the content of phosphoric acid in the extract and the purification from coextracted mineral acids and salts.
