Description
Najdluzszy czas trwania patentu do 16 wrzes'nia 1946 r.W patencie glównym Nr 14537 i w pa¬ tencie dodatkowym Nr 14935 opisano spo¬ soby przerobu soli potasowych, polegajace na tern, ze stosuje sie amon jak, jako po¬ srednik reakpji, i ze magnez zawarty w so¬ lach potasowych wydziela sie w postaci fo¬ sforanu magnezowo-amonowego. Jezeli zwiazki magnezowe sa obecne w surowcu w postaci siarczanów, to wówczas reszta kwasowa laczy sie z amonjakiem i po od¬ dzielenia dwuweglanu sodowego z lugu ma¬ cierzystego otrzymuje sie siarczan amonu razem z chlorkiem amonu. Stwierdzono, ze po uprzedniem oddzieleniu magnezu w po¬ staci fosforanu magnezówó-amonowego o- becne siarczany mozna przeprowadzic w siarczan potasu przez wpuszczenie amon ja¬ ku do roztworu, z którego oddzielono fo¬ sforan magnezowy, A wiec, pomiedzy siar¬ czanem amonowym i chlorkiem potasowym nastepuje podwójna wymiana, przyczem wydziela sie siarczan potasu, a chlorek a- monu pozostaje w roztworze. Roztwór od¬ dzielony od siarczanu potasu zostaje pozba¬ wiony czesci nadmiaru amon jaku i zostaje przerobiony na dwuweglan sodowy przez traktowanie kwasem weglowym.Celem przeprowadzenia sposobu poste-puje sie najkorzysrtniej w ten sposób, ze su¬ rowa sól potasowa wrzuca sie do roztwo¬ ru lkvfasu fosforowego i zawiesine traktuje amonjakiem. Obecny magnez przechodzi przytem w miare wpuszczania amonjaku, w fosforan magnezowo-amonowy, który wydziela sie z powodu swej nierozpuszczal- nosci. Po wydzieleniu wszystkiego magne¬ zu oddziela sie go od lugu macierzystego, który traktuje sie amonjakiem celem wy¬ dzielenia siarczanu potasu.Siarczan potasu wydziela sie tak dalece, ze roztwór jest praktycznie wolny od zwiaz¬ ków potasu. Otrzymany lug macierzysty u- walnia sie najpierw od czesci amoniaku, doprowadzanego w celu wytracenia osadów, i nastepnie doprowadza C02. Mozna przy¬ tem postapic w ten sposób, ze najpierw do¬ prowadza sie C02 az do chwili utworzenia sie obojetnego weglanu sodu, a nastepnie przez oziebienie roztworu wedlug znanego sposobu Schreib'a wydziela sie czesc chlor¬ ku amonu. Roztwór oddzielony od chlorku amoniu nasyca sie C02 dalej, przyczem wy¬ pada dwuweglan sodowy. Przez odparo¬ wanie lugu macierzystego po dwuweglanie sodowym otrzymuje sie wieksza czesc chlor¬ ku amonowego, podczas gdy lugf ostatecz¬ ne dodaje sie podczas rozpuszczania suro¬ wej soli potasowej. PLThe longest duration of the patent until September 16, 1946 The main patent No. 14537 and the additional patent No. 14935 describe methods for the processing of potassium salts, consisting in the use of ammonium as an intermediary of the reaction, and the magnesium contained isolates in potassium salts in the form of magnesium ammonium phosphate. If the magnesium compounds are present in the raw material in the form of sulphates, the acid residue is combined with the ammonium hydroxide, and after separation of the sodium bicarbonate from the mother liquor, ammonium sulphate is obtained together with ammonium chloride. It has been found that, after the magnesium has been separated off in the form of magnesium ammonium phosphate, the sulfates present can be converted to potassium sulfate by introducing ammonium into the solution from which the magnesium phosphate has been separated, that is, between the ammonium sulfate and With potassium chloride, a double exchange takes place, with the release of potassium sulphate and the mononium chloride remaining in solution. The solution separated from the potassium sulphate is deprived of some of the excess ammonium and is converted to sodium bicarbonate by treatment with carbonic acid. The method is most preferably carried out by throwing crude potassium salt into the solution. Phosphorus acid and the suspension are treated with ammonia. The magnesium present is also converted into ammonium chloride, into magnesium ammonium phosphate, which is released because of its insolubility. After all the magnesium has been isolated, it is separated from the mother liquor which is treated with ammonia to separate the potassium sulphate. Potassium sulphate is released to such an extent that the solution is practically free of potassium compounds. The mother liquor obtained is first freed from a portion of the ammonia supplied for sedimentation and then supplied with CO2. In this case, it is possible to proceed in such a way that, first, CO 2 is added until inert sodium carbonate is formed, and then, by cooling the solution according to the known Schreib method, part of the ammonium chloride is released. The solution separated from the ammonium chloride becomes saturated with CO 2 further and sodium bicarbonate precipitates out. By evaporating the sodium bicarbonate mother liquor, the greater part of the ammonium chloride is obtained, while the final liquid is added while the crude potassium salt is dissolved. PL
