Description
Technicznie cenne sole amonowe otrzy¬ muje sie w ten sposób, ze amonjak otrzy¬ many na drodze syntetycznej wiaze sie bezposrednio z kwasami lub tez traktuje gips amon jakiem i kwasem weglowym, o- trzymujac duze ilosci siarczanu amonowe¬ go.Stwierdzono, ze kwasne skladniki soli magnezowych mozna równiez zwiazac z a- monjakiem, o ile za posrednik reakcji u- zyje sie kwas fosforowy; magnez zawarty w tych solach straci sie w postaci nierozpu¬ szczalnego fosforanu magnezu. Uzywa sie do tego kwas fosforowy, otrzymany np. przez traktowanie surowych fosforanów kwasem siarkowym, lub tez syntetyczny, otrzymywany z pierwiastkowego fosforu lub pieciotlenku fosforu.Kwas fosforowy zadaje sie obliczona iloscia soli magnezowej, np. siarczanu ma¬ gnezowego, i skutkiem dodatku amonjaku, najkorzystniej w postaci gazu, straca fosfo¬ ran magnezowo-amonowy. Mozna równiez jednak kwas fosforowy najpierw potrakto¬ wac amonjakiem, a potem dodatkiem soli magnezowej wytracic fosforan magnezu. W roztworze, oddzielonym od fosforanu ma- gnezowo-amonowego, znajduje sie sól a- monowa, która wydziela sie stad w znany sposób. Zamiast czystej soli magnezowejmozna równiez stosowac taka, która prócz zwiazków magnezowycK zawiera jeszcze innevsole^Ghodbi%j4aj. w pierwszym rze¬ dzie o sole potasowe, których zawartosc magnezowa mozna wykorzystac w dogod¬ ny sposób.Jezeli do stracania fosforanu magne- zowo-amonowego uzyje sie karnalitu, wów¬ czas w lugu, oddzielonym od wytraconego fosforanu magnezowo-amonowego, pozo¬ staje chlorek amonu i chlorek potasu, któ¬ re mozna otrzymac przez silne oziebianie lub odparowanie w postaci mieszanej soli albo tez kazdy oddzielnie. Jesli sie uzywa soli potasowej, zasobnej w sól kuchenna, wówczas z lugu ostatecznego usuwa sie sól kuchenna, np. przez warzenie, i otrzymuje sie równiez i tutaj mieszanine soli amono¬ wej i soli potasowej, które w razie potrze¬ by mozna od siebie oddzielic.Jezeli do przeprowadzenia niniejszego wynalazku rozporzadza sie kwasem fosfo¬ rowym lub roztworami, zawiera jacemi kwas fosforowy, otrzymanemi przy trakto¬ waniu surowych fosforanów kwasami mi- neralnemi, wówczas, w zaleznosci od uzy¬ tych kwasów mineralnych, wynikaja roz¬ maite mozliwosci.Traktujac kwasem siarkowym, otrzy¬ muje isie roztwór kwasu fosforowego, któ¬ ry mozna bezposrednio przerobic powyz¬ szym sposobem przez dodanie soli magne¬ zowej i traktowanie amonjakiem* Jesli jednak surowy fosforan traktuje sie kwasem solnym lub azotowym, to naj¬ pierw otrzymuje sie roztwór, który obok kwasu fosforowego zawiera chlorek wapnia lub azotan wapnia. W tym wypadku stra¬ ca sie wapien w postaci siarczanu wapnia przez dodanie siarczanu magnezu lub soli, zawierajacych siarczan magnezu, i traktu¬ je roztwór, uwolniony od osadu siarczanu wapnia, amon jakiem, przyczem wypada mieszanina fosforanu magnezowego z fosfo¬ ranem amonowo-magnezowym. Roztwór u- wolniony od osadu przerabia sie dalej na sole amonowe lub mieszaniny soli amono¬ wych i potasowych, poczem j eszcze raz oddziela sie sole amonowe od potasowych.Wkoncu nalezy podkreslic, ze z kwasu fosforowego lub roztworów, zawierajacych kwas fosforowy, najpierw oddziela sie czesc kwasu fosforowego, jako fosforan a- monowy, a reszte, wedlug sposobu niniej¬ szego wynalazku, otrzymuje sie jako fosfo¬ ran magnezowo-^monowy. PLThe technically valuable ammonium salts are obtained by making the ammonia obtained synthetically either directly with acids or by treating the gypsum with ammonium and carbonic acid, keeping large amounts of ammonium sulphate. It has been found that the acidic components are Magnesium salts can also be associated with an anoma, as long as phosphoric acid is used as the reaction mediator; the magnesium in these salts will be lost as insoluble magnesium phosphate. Phosphoric acid is used for this, e.g. by treating crude phosphates with sulfuric acid, or also synthetic acid, obtained from elemental phosphorus or phosphorus pentoxide. Phosphoric acid is given the calculated amount of a magnesium salt, e.g. magnesium sulphate, and by adding ammonia, most preferably in the form of a gas, the magnesium ammonium phosphate is lost. However, it is also possible to treat the phosphoric acid first with ammonia and then by the addition of magnesium salt to destroy the magnesium phosphate. In the solution, separated from the magnesium ammonium phosphate, there is an a-mono salt which is isolated from here in a known manner. Instead of pure magnesium salt, it is also possible to use one which, apart from magnesium compounds, also contains other salts. in the first place for potassium salts, the magnesium content of which can be conveniently utilized. If carnallite is used to lose magnesium ammonium phosphate, then in the liquor separated from the precipitated magnesium ammonium phosphate, it remains ammonium chloride and potassium chloride, which may be obtained either by strong cooling or evaporation in the form of mixed salt, or each separately. If potassium salt is used, which is rich in table salt, the table salt is removed from the final liquor, e.g. by boiling, and a mixture of ammonium salt and potassium salt is obtained here, which can be separated from each other if necessary. If phosphoric acid or solutions are used to carry out the present invention, and contains phosphoric acid, obtained from the treatment of crude phosphates with mineral acids, then, depending on the mineral acids used, various possibilities result. sulfuric acid, a phosphoric acid solution is obtained, which can be processed directly by the above method by adding magnesium salt and treating with ammonia. If, however, the crude phosphate is treated with hydrochloric or nitric acid, the solution is first obtained, which, in addition to phosphoric acid, contains calcium chloride or calcium nitrate. In this case, limestone is lost in the form of calcium sulphate by adding magnesium sulphate or salts containing magnesium sulphate, and the solution, freed from the calcium sulphate sediment, is treated with ammonium, resulting in a mixture of magnesium phosphate and ammonium magnesium phosphate. . The solution freed from the sediment is further processed into ammonium salts or mixtures of ammonium and potassium salts, and then the ammonium and potassium salts are separated once more. Finally, it should be emphasized that from phosphoric acid or solutions containing phosphoric acid, it is first separated some phosphoric acid is obtained as alumic phosphate and the rest, according to the method of the present invention, is obtained as magnesium mononium phosphate.
