Description
Verfahren zur Herstellung saurer Natriumforrniate. Nach der Erfindung gelingt die Herstellung von sauren N atriumformiaten von verschiedenem Säuregehalt in überraschend einfacher Weise durch Eintragen von Natriumformiat in wässerige Ameisensäure.Process for the production of acidic sodium formates. According to the invention the production of acidic sodium formates with different acid contents succeeds in a surprisingly simple manner by introducing sodium formate in aqueous Formic acid.
!n Ausübung der Erfindung kann man z. B. derart verfahren, daß man in wässerige Ameisensäure, deren Ameisensäuregehalt mehr als 20 Prozent betragen muß, technisches \ atriuinformiat, gegebenenfalls unter Erwärmen, einträgt. -Bei Abkühlung der Mischung auf Zimmerteinperatur scheiden sich die sauren Formiate in Form wohlausgebildeter Kristalle ab, welche durch einfaches Zentrifugieren von der lZutterlauge getrennt werden können.When practicing the invention, one can e.g. B. proceed in such a way that one in aqueous formic acid, the formic acid content of which is more than 20 percent must, technical \ atriuinformiat, if necessary with heating, enters. -At When the mixture cools down to room temperature, the acidic formates separate into Form well-formed crystals, which by simple centrifugation from the l Feed liquor can be separated.
Geht man von einer Ameisensäure aus, deren Gehalt an Ameisensäure weniger als 5o Prozent beträgt, so erhält man ein Trinatriumhydroformiat Na"H(HCOO)4, während bei Verarbeitung von Säuren, welche mehr als 5o Prozent Ameisensäure enthalten, entweder N atriuinbiformiat oder ein Gemisch der beiden sauren Formiate erhalten wird.If one assumes a formic acid, its content of formic acid is less than 50 percent, a trisodium hydroformate Na "H (HCOO) 4 is obtained, while when processing acids that contain more than 50 percent formic acid, obtained either N atriuinbiformiat or a mixture of the two acidic formates will.
Das Trinatriumhydroformiat kann, wie gefunden wurde, in einfachster Weise, z. B. durch einfaches Schütteln mit einer wässerigen Ameisensäure von entsprechender Konzentration, z. B. einer solchen von etwa Oo Prozent, in Natritnnbiforiniat übergeführt werden. Beispiele. 1. loo kg 50prozentiger Ameisensäure werden mit ioo kg technischem Natriumformiat zusammengerührt. -Nach dem Abkühlen des Reaktiongemisches auf gewöhnliche Temperatur können 16o kg Trinatriumhydroformiat durch Abtrennen von der Mutterlauge gewonnen werden. Die Mutterlauge, die eine mit N atriumformiat gesättigte, etwa 30prozentige Ameisensäure darstellt, kann je nach dem gewünschten Zwecke weiterverarbeitet werden, z. B. nach Zusatz einer stärkeren Säure zum Ansatz einer neuen Mischung.The trisodium hydroformate can, as has been found, in the simplest way Way, e.g. B. by simply shaking with an aqueous formic acid of the appropriate Concentration, e.g. B. one of about Oo percent, converted into sodium bicarbonate will. Examples. 1. 100 kg of 50 percent formic acid are mixed with 100 kg of technical Sodium formate stirred together. -After cooling the reaction mixture to ordinary Temperature can be achieved by separating 16o kg of trisodium hydroformate from the mother liquor be won. The mother liquor, which is saturated with sodium formate, is about 30 percent formic acid can be further processed depending on the desired purpose be e.g. B. after adding a stronger acid to the approach of a new mixture.
z. 1 io kg Natriumforiniat (technisch) «-erden in ioo kg 80prozentige Ameisensäure eingerührt. -Nach dem Abkühlen des Gemisches können bei gewöhnlicher Temperatur 11,4 kg Natriuinbiforiniat durch Schleudern erhalten werden. Die 'Mutterlauge besteht aus einer mit Natriumformiat gesättigten, et-,va 65prozentigen Ameisensäure und kann zur direkten Darstellung vonTr inatriumlivtIroformiat oder nach Zusatz einer stärkeren Ameisensäure zur erneuten Herstellung von Natriumbiforniiat verwendet werden.z. 10 kg of sodium formate (technical) «earth in 100 kg of 80 percent strength Formic acid stirred in. -After the mixture has cooled down, you can use the ordinary Temperature 11.4 kg Natriuinbiforiniat can be obtained by centrifugation. The 'mother liquor consists of an ethyl, above all 65 percent formic acid saturated with sodium formate and can be used for the direct representation of Tr inatriumlivtIroformiat or after addition a stronger formic acid used to re-produce sodium carbonate will.
3. 125 kg Trinatriumlivdroforiniat werden in ioo kg etwa ; 5prozentige Ameisensäure eingerührt. Es können in ähnlicher Weise, wie oben, 114 kg Natritunliiforiuiat gewonnen werden.3. 125 kg of trisodium livdroforiniat are approximately 100 kg; 5 percent Formic acid stirred in. In a similar way as above, 114 kg of natritunliiforiuiat can be used be won.
