Description
Verfahren zur Herstellung von beständigen Ferroeisen-Lösungen Zusatz zum Patent 693248 In weiterer Ausbildung des Verfahrens nach Patent 693 248 wurde gefunden, daß man bei der - Herstellung stabiler Ferroeisenlösungen mit der Temperatur herabgehen kann, ohne den Eisengehalt der Lösung dadurch zu vermindern, oder aber auch bei gleicher Temperatur wie bei dem Verfahren des Hauptpatents den Eisengehalt der Lösung. erheblich steigern kann, wenn man der Glucoselösung geringe Mengen organischer Säuren hinzufügt und diese sauren Lösungen gemäß dem Verfahren des Hauptpatents auf Eisen zur Einwirkung gelangen läßt. Dadurch wird eigentümlicherweise rneihr Eisen -in Lösung gebracht, als durch die Erhöhung des Eisengehalts entsprechend der zugesetzten Menge Säure erwartet werden konnte.Process for the production of permanent ferrous iron solutions Additive for patent 693248 In a further development of the process according to patent 693248 was found that in the - production of stable ferrous iron solutions with the temperature can go down without reducing the iron content of the solution, or else the iron content even at the same temperature as in the process of the main patent the solution. Can increase significantly if you add small amounts of organic to the glucose solution Adds acids and these acidic solutions according to the method of the main patent can act on iron. Strangely, this becomes her Iron brought into solution than by increasing the iron content accordingly the amount of acid added could be expected.
Ferner unterscheidet sich das Verfahren noch vorteilhaft von dem Verfahren des Hauptpatents, daß es möglich ist, schon bei niedrigeren T,emperaturen Lösungen mit praktisch brauchbarer Eisenkonzentration zu erhalten.Furthermore, the method differs advantageously from the method of the main patent that it is possible, even at lower T, temperature solutions with practically usable iron concentration.
Beispiel I 10 Teile Ferrum reductum werden. mit einer Lösung von I25 Teilen Glucose sowie 10 Teilen Citronensäure in 500 Teilen Wasser in einem Autoklaven auf etwa 1200 erhitzt. Example I 10 parts of Ferrum reductum become. with a solution of I25 parts of glucose and 10 parts of citric acid in 500 parts of water in an autoclave heated to around 1200.
Nach etwa 5 Stunden läßt man abkühlen und filtriert die braune Lösung von ungelösten Anteilen ab. Nach Auffüllen auf ein Gesamtvolumen von 5oo Teilen enthält die Lösung etwa I% Eisen in der Ferrnform.After about 5 hours, the mixture is allowed to cool and the brown solution is filtered of unresolved parts. After filling up to a total volume of 500 parts the solution contains about 1% iron in the ferric form.
Beispiel 2 25 Teile Ferrum reductum wo den mit einer Lösung von I25 Teilen Glucose und -10 Teilen Citronensäure in 500 Teilen Wasser im geschlossenen Gefäß etwa 5 Stunden auf 140 erhitzt. Der Überdruck beträgt etwa 4 Atm. Nach dem Erkalten wird vom Ungelösten abfiltnert und das dunkelbraune Filtrat auf 500 Teile mit Wasser aufgefüllt. Der lEisengehalt der Lösung beträgt etwa 2,5%. Example 2 25 parts of Ferrum reductum where the with a solution of I25 Parts of glucose and -10 parts of citric acid in 500 parts of water in the closed Vessel heated to 140 for about 5 hours. The overpressure is about 4 atm. After this Cooling is filtered off from the undissolved and the dark brown filtrate to 500 parts topped up with water. The iron content of the solution is about 2.5%.
