. Bei der Herstellung von Kaliumpersulfat durch Elektrolyse von Lösungen von Kaliumbisulfat erzielt man nur eine Stromausbeute von etwa 40 Prozent. Zur Erhöhung dieser Stromausbeute sind verschiedene Zusätze, vorgeschlagen worden/ z. B. Chlor-, Fluor-, Cyän- oder Rhodan verbindungen. Diese Zusätze haben den Nachteil, daß sie das erzeugte Kaliumpersulfat verunreinigen und für manche Zwecke, unbrauchbar machen.. In the manufacture of potassium persulfate by electrolysis of solutions of potassium bisulfate a power yield of only about 40 percent is achieved. To increase this current yield various additives have been proposed / e.g. B. chlorine, fluorine, cyan or Rhodan compounds. These additives have the disadvantage that they created that Contaminate potassium persulphate and, for some purposes, render it unusable.
,Die vorliegende Erfindung beruht darauf, daß man. bei der Herstellung von Kaliumpersulfat' durch direkte Elektrolyse als Elek-, The present invention is based on that he. in the production of potassium persulphate 'by direct electrolysis as an elec-
V?' trbiyt'Lösürigeri verwendet, die neben Kaliumbisülfät erhebliche Mengen von Sulfaten oder Bisulfaten des Natriums oder des Ammoniums öder beider zugleich enthalten.V? ' trbiyt'Lösürigeri used, in addition to potassium bisülfät considerable amounts of sulphates or bisulphates of sodium or ammonium or both at the same time.
Es, wurde gefunden, daß diese Ausbeute erheblich gesteigert werden kann durch diesen Zusatz von Natrium- oder Ammoniumsulfat bzw. -bisulfat zum Elektrolyten. Die Ausbeute steigt auf das 1Z2- bis 2 fache. Es war nicht vorauszusehen, daß z. B. ein Zusatz von Natriumbisulfat günstig auf die Elektrolyse einwirke, weil bei der Elektrolyse von Natriumbisulfat allein zur Herstellung von Natrmmpersulfat' nur eine wesentlich niedrigere Ausbeute erzielt wird. Es wurde zudem gefunden, daß das so erzeugte Kaliumpersulfat keine oder doch nur wenig Natrium- oder Ammoniumsalze enthält und in besser ausgebildeten Kristallenen und dadurch besser verarbeitbar -und auch höherprozentig ausfällt. Während das aus reinen Kaliumbisulfatlösungen hergestellte Kaliumpersulfat 5 bis· 10 Prozent Kaliumsulfat enthält, erhält man aus einer Lösung, die gleichzeitig Natrium- oder Ammoniumsulfat enthält, direkt ein ggprozentiges Kaliumpersulfat.It has been found that this yield can be increased considerably by adding sodium or ammonium sulfate or bisulfate to the electrolyte. The yield increases to 1 Z 2 - to 2 times. It was not foreseeable that z. B. an addition of sodium bisulfate has a favorable effect on the electrolysis, because in the electrolysis of sodium bisulfate alone for the production of sodium persulfate 'only a much lower yield is achieved. It has also been found that the potassium persulfate produced in this way contains no or only a few sodium or ammonium salts and is precipitated in better formed crystals and thus easier to process and also in higher percentages. While the potassium persulphate produced from pure potassium bisulphate solutions contains 5 to 10 percent potassium sulphate, a solution which also contains sodium or ammonium sulphate directly gives a half-percentage potassium persulphate.
