Verfahren zur Darstellung von Perboraten. Patentiert im Deutschen Reiche vom 19. April 1913 ab.Procedure for the representation of perborates. Patented in the German Empire on April 19, 1913.
Nach den bisherigen technisch ausgeführten Verfahren zur Darstellung von Perboraten und Perborax geht man von sehr teuren Rohstoffen aus, vom Natriumsuperoxyd, Natriumpercarbonat oder Perhydrol, oder man arbeitet mit dem technischen, nur 3 Prozent enthaltenden, unreinen Wasserstoffsuperoxyd und erhält eine Unmenge an Lösungen.According to the previous technically executed method for the representation of perborates and Perborax is based on very expensive raw materials, sodium peroxide and sodium percarbonate or Perhydrol, or you work with the technical, only 3 percent containing, impure hydrogen peroxide and contains a vast number of solutions.
Nach vorliegender Erfindung benutzt man dagegen das billigste, reinste und konzentrierteste Wasserstoffsuperoxyd, das überhaupt herzustellen geht — das Wasserstoffsuperoxyd in Gasform.According to the present invention, on the other hand, the cheapest, purest and most concentrated is used Hydrogen peroxide that can ever be manufactured - the hydrogen peroxide in gaseous form.
Das gasförmige Wasserstoffsuperoxyd kann durch Destillation seiner wäßrigen Lösungen unter Vakuum ,hergestellt werden; dies Verfahren erfordert jedoch viel Heizmittel und ist mit großen Verlusten verbunden; oder man entbindet aus Persulfaten oder anderen Wasserstoffsuperoxyd liefernden Salzen das Wasserstoffsuperoxyd mittels Säuren und saugt unter Vakuum oder durch einen Luftstrom das Gas im statu nascendi ab. Das einfachste und billigste Verfahren dagegen besteht darin, daß man Persäuren der Destillation unterwirft und das entbundene gasförmige Wasserstoffsuperoxyd direkt in die Lösung von Boraten oder Lösung von Borsäure unter Zugabe des nötigen Alkalis einleitet bzw. durch diese Lösungen durchsaugt, wenn nötig unter Kühlung.The gaseous hydrogen peroxide can be obtained by distilling its aqueous solutions under vacuum; however, this method requires a lot of heating means and is associated with great losses; or one releases from persulfates or other hydrogen peroxide supplying salts the hydrogen peroxide by means of acids and sucks the under vacuum or through a stream of air Gas off in statu nascendi. The simplest and cheapest way to counter this is to that one subjects peracids to the distillation and the released gaseous hydrogen peroxide introduced directly into or through the solution of borates or solution of boric acid with the addition of the necessary alkali Solutions sucked through, if necessary with cooling.
Da das Gas durch mehrere hintereinander aufgestellte Absorptionsgefäße hindurchgesaugt werden kann, ist jeder Verlust an Wasserstoffsuperoxyd ausgeschlossen. An Stelle der teuren, aus reinem Borax oder reiner Borsäure und Ätznatron hergestellten Lösungen kann man vorteilhafter verwenden die filtrierten Aufschlußlösungen der Borsäure- oder Boraxfabrikation oder noch vorteilhafter die Mutterlaugen von der Borax- und Borsäurekristallisation — es ist also am' rationellsten, die Perboratfabrikation sowohl mit der Persäure-, als auch mit der Borax- oder Borsäuredarstellung in Verbindung zu bringen.Because the gas is sucked through several absorption vessels placed one behind the other any loss of hydrogen peroxide is excluded. Instead of expensive solutions made from pure borax or pure boric acid and caustic soda it is more advantageous to use the filtered digestion solutions of boric acid or Borax production or, even more advantageously, the mother liquors from borax and boric acid crystallization - It is therefore the most rational to use the perborate production both with the peracid, as well as with the representation of borax or boric acid.
Die Vorteile des vorliegenden Verfahrens gegenüber den bisherigen sind folgende:The advantages of the present method over the previous ones are as follows:
1. Das aus dem teuren Natriumsuperoxyd oder Natriumpercarbon at oder Perhydrol gewonnene Wasserstoffsuperoxyd ist ein für technischen Gebrauch viel zu teures Präparat; billiger und vorteilhafter als nach der vorliegenden Erfindung kann das Perborat nach keinem der bisherigen Verfahren dargestellt werden.1. That obtained from the expensive sodium peroxide or sodium percarbonate or perhydrol Hydrogen peroxide is a preparation that is far too expensive for technical use; cheaper and more advantageous than according to the present invention, the perborate can none of the previous procedures are presented.
2. Nach dem vorliegenden Verfahren arbeitet man mit reinem gasförmigen Wasserstoffsuperoxyd und erhält Perborate in größter Reinheit, ohne das teure Kühlen großer Flüssigkeitsmengen nötig zu haben.2. The present process uses pure gaseous hydrogen peroxide and receives perborates in the greatest purity, without the expensive cooling of large amounts of liquid need to have.
3. Vor allem kann mit viel konzentrierteren Lösungen gearbeitet werden, man erspart daher viel an Apparatur, Lohn und Zeit.3. Above all, you can work with much more concentrated solutions, so you save a lot of equipment, wages and time.
