Description
Pierwszenstwo: 5 grudnia r^2.S r. (Niemcy;.Najdluzszy czas trwania patentu do 28 grudnia 1046 r.Wedlug patentu Nr 15334 wytwarza sie KNOs przy równoczesnem otrzymywa¬ niu MgHP04, przyczem surowy fosforan rozpuszcza sie zapomoca HNO.s i K2S04, a z tak otrzymanego roztworu straca H?P04, jako MgHP04.Ten sam wynik mozna osiagnac, zaste¬ pujac czesciowo K2S04 przez MgS04, do czego moze byc uzyty kizeryt lub sól gorz¬ ka, lub zastepujac oba srodki K2S04 i MgS04 zupelnie lub czesciowo przez szenit (K2S04, MgS04, 6H20), leonit (K2S04, 2 MgS04, 4 H20) lub langbeinit (K2S04, 2 MgS04). Ilosc Mg nalezy dobierac rów¬ noznaczna do ilosci P2Or, wedlug wzoru MgHP04.Po oddzieleniu gipsu zobojetnia sie po¬ zostalosc zapomoca K2CO^f przyczem o- trzymuje sie MgHP04. Ten MgHP04 od¬ dziela sie, wyplókuje i suszy, uzywajac bezposrednio, jako nawóz, lub przerabia dalej na nawóz. Aby otrzymac czysty MgHPOi postepuje sie z korzyscia w ten sposób, ze najpierw straca sie H?P04 nie zupelnie, lecz pozostawia nieco, np. 1 %, w roztworze, oddziela MgHP04, a nastepnie zobojetnia lug macierzysty zupelnie zapo¬ moca K2COz, przyczem otrzymuje sieMg3(P04)2f uzywany przy nastepnej ope¬ racji do stracania MgHP04.Z lugu macierzystego otrzymuje sie KN03 przez chlodzenie lub wyparowanie.Zachodzace reakcje chemiczne mozna zestawic w nastepujace równania: Ca3(POJ2+6HN03+2MgS04+K2S04 = = 3 CaS04 + 2H3 PO, + 2 Mg(N03)2 + + 2 KN03 2 H3 P04 '+ 3 Mg(N0J2 + 3 K2C03 = = Mg3fPOJ2+6 KN03+3 C02+3 H20 Mg, (P0J2 +H3 P04=3 MgHP04. PLPriority: December 5, 2nd September (Germany; the longest term of the patent until December 28, 1046, according to patent No. 15334, KNOs is produced with the simultaneous preparation of MgHP04, because the raw phosphate dissolves with HNO.si and K2SO4, until the solution thus obtained loses H ?PO4 as MgHP04. The same result can be achieved by partially replacing K2SO4 by MgSO4, for which kieserite or bitter salt may be used, or by replacing both K2SO4 and MgSO4 completely or partially by chenite (K2SO4, MgSO4, 6H2O), leonite (K2SO4, 2 MgSO4, 4 H2O) or langbeinite (K2SO4, 2 MgSO4). The amount of Mg should be selected equal to the amount of P2Or, according to the formula MgHP04. After separation of the gypsum, the residue becomes neutral. With the help of K2CO ^ f, it adheres to MgHP04. This MgHP04 is separated, fled and dried, either used directly as a fertilizer, or further processed into fertilizer. To obtain pure MgHPOi, the advantage is that it is first lost H? P04 not completely, but leaves some for example, 1% in solution separates the MgHPO 4, then neutralizes the mother liquor completely with K 2 CO 2, resulting in Mg 3 (PO 4) 2f used in the next operation to lose MgHPO 4. The mother liquor is obtained from KN 3 3 by cooling or evaporation. The chemical reactions taking place can be summarized in the following equations: Ca3 (POJ2 + 6HN03 + 2MgS04 + K2S04 = = 3 CaS04 + 2H3 PO, + 2 Mg (NO03) 2 + + 2 KN03 2 H3 P04 '+ 3 Mg (N0J2 + 3 K2C03 = = Mg3fPOJ2 + 6 KN03 + 3 CO2 + 3 H20 Mg, (P0J2 + H3 P04 = 3 MgHP04.
