Description
Najdluzszy czas trwania patentu do 16 wrzesnia 1946 r.W patencie Nr 14537 opisany jest spo¬ sób przerobu .soli potasowych, w którym u- zywa sie amon jak, jako posrednik reakcji, w celu rozlozenia soli potasowych na czesci skladowe. Zdolano stwierdzic, ze magnez mozna korzystnie oddzielic od innych cze¬ sci skladowych pod postacia fosforanu ma- gnezowo-amonowego. W ten sposób nietylko zyskuje sie nowy cenny nawóz, lecz rów¬ niez ma sie te korzysc, ze mozna lugi tak dalece uwolnic od zwiazków magnezowych, ze te nie przeszkadzaja przy wytracaniu dwuweglanu sodowego zapomoea amonja- ku i kwasu weglowego. Okazalo sie miano¬ wicie, ze w przypadku, gdy naweglany lug zawiera jeszcze znaczniejsze ilosci soli ma- gneizowych, wówczas dwuweglan sodowy wypada w postaci mazistej, trudnej do sa¬ czenia. Jezeli natomiast magnez zostaje wy dzielony, jako fosforan magnezowo- a- monowy, wówczas otrzymuje sie lugi, na¬ dajace sie doskonale do wytracenia dwu¬ weglanu.Sposób przeprowadza sie, jak podano ponizej. Lugi pozostale po wytraceniu siar¬ czanu potasu i zawierajace duze ilosci a- moinjaiku zadaje sie fosforanami potasow- cowemi np. fosforanem amonowym lub tez^jkwasem fosforowymi. Pmzytem magnez ^•Wypada praktycznie calkowicie jako fosfo¬ ran maj^nizzo^-aiiionowy, który znanym sposobem latwo oddziela sie od lugów ma- cierzysitych.Mozna jednak równiez postepowac w ten sposób, ze czesc magnezu, jak to opisa¬ no w patencie Nr 14537, oddziela sie w po¬ stapi trójwodneigo weglanu magnezu lub weglanu magnezowo-amonowego, a reszte straca jako fosforan magnezowo-amonowy.Ostatecznie mozna wogóle zrezygnowac z wytracenia siarczanu potasu, co stanowi¬ lo pierwsze stad jurni sposobu wedlug paten¬ tu Nr 14537, i roztwór surowej soli pota¬ sowej wytracac bezposrednio zapoimoca fo¬ sforanu potasowcowego lub kwasu fosforo¬ wego, zapewniwszy uprzednio obecnosc do- statecznych Hosci amoniaku i chlorku amo¬ nu. Do wytracenia fosforanu magnezowo- amonowego najlepie j uzywac iosforon amo¬ nowy lub tez kwas fosforowy, jaki powsta¬ je pmzy syntetycznym sposobie otrzymywa¬ nia kwasu fosforowego lub jaki sie otrzy¬ muje przy rozkladzie fosforanów wapnia kwlasetm siarkowym. PLThe longest term of the patent until September 16, 1946 Patent No. 14537 describes a method of processing potassium salts, which uses ammonium as a reaction medium to break down the potassium salts into its constituent parts. It has been found that the magnesium can be advantageously separated from the other constituents in the form of magnesium ammonium phosphate. In this way, not only is a valuable new fertilizer obtained, but the advantage is also that the lags can be freed from the magnesium compounds to such an extent that they do not interfere with the deposition of sodium bicarbonate by ammonia and carbonic acid. It turned out that, if the carbonated liquor contains even greater amounts of magnesium salts, then the sodium bicarbonate falls out in a greasy, difficult to saturate form. If, on the other hand, the magnesium is separated as magnesium-ammonium phosphate, a lump is obtained which is perfectly suitable for the precipitation of bicarbonate. The procedure is carried out as follows. The liquors remaining after the precipitation of the potassium sulphate and containing large amounts of the amino acid are mixed with potassium phosphates, for example with ammonium phosphate or also with phosphoric acid. With magnesium, it is practically completely as phosphorus, a nizole-aionic, which is easily separated from the mother's thrust in a known manner. However, it is also possible to proceed in such a way that a part of the magnesium, as described in the patent No. 14537, the trihydrate of magnesium carbonate or magnesium ammonium carbonate is separated, and the rest is lost as magnesium ammonium phosphate. Ultimately, it is possible to abandon the depletion of potassium sulphate, which was the first stage of the method according to patent No. 14537, and the crude potassium salt solution should be precipitated directly in advance of potassium phosphate or phosphoric acid, having first ensured that sufficient ammonia and ammonium chloride are present. For the destruction of magnesium ammonium phosphate, it is best to use ammonium phosphate or also phosphoric acid, which is produced by a synthetic method of obtaining phosphoric acid or obtained by decomposing calcium phosphates with sulfuric acid.
