Description
Najdluzszy czas trwania patentu do 8 listopada 1941 r.W patencie Nr 6265 opisano sposób o- trzymywania sztucznych nawozów, pole¬ gajace na tern, ze mieszaniny surowych fo¬ sforanów z kwasem krzemowym i siarcza¬ nami alkaljów albo ich chlorkami lub mie¬ szaniny ich poddaje sie prazeniu w obec¬ nosci pary wodnej. Przytem na jeden mol kwasu fosforowego w mieszaninie przypa¬ da nieco wiecej, niz inol kwasu krzemo¬ wego.Niespodziewanie wykryto, ze przy uzy¬ ciu soli sodowych, a wiec chlorku i siar¬ czanu sodowego, mozna znacznie zmniej¬ szyc ilosc dodawanego kwasu krzemowe¬ go, a mianowicie w ten sposób, zeby na 1 mol P205 przypadalo tylko pól mola kwa¬ su krzemowego. Kwas krzemowy odciaga z fosforanu trójwapniowego 1 mol CaO, przyczem powstaje fosforan alkali-dwu- wapniowy oraz ortoJkrzemian wapniowy wedlug równania: 2Cas(POJ2 + Si02 + 2Na2SO± = = 2(2CaO.Na2O.P2OJ Si02 + 2S03. + 2CaO.Jezeli fosforyt, uzyty jako materjal wyjsciowy, zawiera równiez wapno nie- zwiazane z kwasem fosforowym, np, we¬ glan wapnia albo fluorek wapnia, to nale-zy uzyc dodatkowa ilosc kwasu krzemowe¬ go, zeby i to wapno równiez przetworzyc na orto^krzemian, Przy uzyciu fosforytów, zasobnych w zelazo i glinke, te ostatnie moga z powo¬ dzeniem zastapic kwas krzemowy, tworzac glinian, wzglednie zelazian wapniowy, wo¬ bec czego nalezy zwracac baczna uwage na sklad chemiczny mieszaniny, poddawa¬ nej prazeniu.Wobec zmniejszenia ilosci dodawanego kwasu krzemowego, dodatek wapna, stoso¬ wany zgodnie z patentem glównym, staje sie zbyteczny tak, iz sposób niniejszy po¬ zwala na uzycie minimalnej ilosci dodat¬ ków oraz produkuje sztuczny nawóz fo¬ sforanowy o wysokiej zawartosci kwasu fo¬ sforowego.Przyklad. 100 czesci pólnocno-afrykan- skiego fosforanu, zawieraj acegoi 39,7% P205, 47,0% CaO, zwiazanego z P2051 da¬ lej 5,6% CaO, niezwiazanego z P205 oraz 0,56% Si021 zmieszano z 11,5 czesciami piasku kwarcowego i 40 czesciami tech¬ nicznego siarczanu sodowego, poczem mie¬ szanine prazono w temperaturze okolo 1100°C przy jednoczesnem przeprowadza¬ niu pary wodnej. Produkt prazenia zawie¬ ral ogólem 32,08% P205 oraz 31,37% P205 rozpuszczalnego w cytrynianach (rozpuszczalnego w roztworze cytrynianu wedlug Petermann'a), A wiec z ogólnej ilosci kwasu fosforowego w mieszaninie zo¬ stalo rozpuszczone 98%, Produkt prazenia zawieral jeszcze tylko 0,32% SOs. PL PLThe longest term of the patent until November 8, 1941. Patent No. 6265 describes a method of obtaining artificial fertilizers, consisting in the fact that mixtures of raw phosphates with silicic acid and alkali sulphates or their chlorides or mixtures are subjected to calcination in the presence of steam. For one mole of phosphoric acid in the mixture slightly more than an inole of silicic acid. It has surprisingly been found that with the use of sodium salts, i.e. chloride and sodium sulphate, the amount of silicic acid added can be significantly reduced That is, in such a way that there is only half a mole of silicic acid per mole of P2O5. Silicic acid extracts 1 mole of CaO from the tricalcium phosphate, which produces alkali-di-calcium phosphate and calcium ortho-silicate according to the equation: 2Cas (POJ2 + Si02 + 2Na2SO ± = 2 (2CaO.Na2O.P2OJ Si02 + 2SO3. + 2CaPhorite. , when used as a starting material, also contains non-phosphoric acid calcium, e.g. calcium carbonate or calcium fluoride, an additional amount of silicic acid must be used to also convert this lime into ortho silicate. With the use of phosphates, rich in iron and clay, the latter can successfully replace silicic acid, forming aluminate or calcium ferric, so careful attention should be paid to the chemical composition of the mixture to be calcined. of silicon dioxide, the addition of lime, used in accordance with the main patent, becomes redundant, so that the present process allows the use of a minimum amount of additives and produces a high acid phosphate artificial phosphoric. Example. 100 parts of North African phosphate containing 39.7% P205, 47.0% CaO bound to P2051, further 5.6% CaO not bound to P205 and 0.56% SiO21 were mixed with 11.5 parts quartz sand and 40 parts of technical sodium sulphate, then the mixture was roasted at a temperature of about 1100 ° C. while steam was carried out. The calcined product contained a total of 32.08% P2O5 and 31.37% citrate-soluble P2O5 (soluble in citrate according to Petermann), so of the total amount of phosphoric acid in the mixture 98% was dissolved. only 0.32% more SOs.
