Description

Verfahren zur Herstellung von Chloraten, Brömaten und Jodaten. Nach dem bisherigen Verfahren zur Herstellung von Chloraten. leitet man Chlor in Laugen von Kali, Natron oder gelöschtem Kalk, wobei höchstens 2-1e der angewandten Chlormenge in Chlorat -umgewandelt wird'., entsprechend der Formel: 6 KOH + 6 Cl - KC103, + 5 KCl + 3 H,0. Eine bedeutend größere Ausbeute an Chlorat bvw. Bromat oder Jodat erzielt man bei Anwendung eines Katalysators und, eines Gemenges von Chlor, bzw. Brom oder Jod und Luft.Process for the production of chlorates, bromates and iodates. To the previous process for the production of chlorates. one passes chlorine in alkalis of potash, soda or slaked lime, with a maximum of 2-1e of the amount of chlorine used is converted into chlorate '., according to the formula: 6 KOH + 6 Cl - KC103, + 5 KCl + 3 H, 0. A significantly larger yield of chlorate bvw. Bromate or iodate is achieved when using a catalyst and a mixture of chlorine or Bromine or iodine and air.

Leitet man zur Ausführung obigen Verfahrens Chlor- bzw. Brom- oder Joddämpfe mit Luft gemischt in konzentrierte, durch Wasser gekühlte Kalilauge, in welcher als Katalysator Mangandioxyd -Mn OZ- enthalten ist, so bewirkt die Kontaktsubstanz, als welche auch jede andere katalytisch wirkende Substanz angewendet werden kann, die Anlagerung des Sauerstoffs der Luft an das Chlor, bzw. Brom oder Jod. Bei Anwendung von. 11,664 g Chlor und einer genügenden Menge Luft wurden hiervon 41,838 Prozent in Chlorat, 57,468 Prozent in Hypochlorit, o,6gq. Prozent in Chlorid übergeführt.If, to carry out the above process, chlorine, bromine or iodine vapors mixed with air are passed into concentrated, water-cooled potassium hydroxide solution, which contains manganese dioxide -Mn OZ- as a catalyst, the contact substance has the same effect as any other catalytically active substance can be applied, the addition of the oxygen in the air to the chlorine, bromine or iodine. When using. 11.664 g of chlorine and a sufficient amount of air were 41.838 percent of this in chlorate, 57.468 percent in hypochlorite, 0.6 gq. Percent converted into chloride.

In .gleicher Weise -erhält man auch Chlorate, wenn man statt Chlor oder Brom oder Tod und Luft deren Wasserstoffverbindungen, z. B. Salzsäure mit Luft gemischt, anwendet. Desgleichen werden nach .obigem Verfahren Chlorate, Bromate und. Jodate erzeugt, wenn man anstatt die Elemente Chlor, Brom oder Jod als solche hinzuzuführen, dieselben aus ihren Verbindungen, sei es auf rein chemischem oder elektrochemischem Wege erzeugt und im Entstehungszustande bei Gegenwart einer Kontaktsubstanz Luft hinzuführt. .In the same way, one also obtains chlorates if one instead of chlorine or bromine or death and air their hydrogen compounds, e.g. B. hydrochloric acid with air mixed, applies. In the same way, chlorates, bromates and. Iodates are produced if one uses instead of the elements chlorine, bromine or iodine as such to add them from their combinations, be it purely chemical or Electrochemical generated and in the state of formation in the presence of a contact substance Adds air. .

Läßt man z. B. Salzsäure auf Mangandioxyd einwirken, so wird: Chlor freigemacht, welches dann nach obigem Verfahren durch den Sauerstoff der Luft unter Mitwirkung von weiterem Mangandioxyd als Kontaktsubstanz zu Chlorsäure oxydiert wird. Es entsteht also Mänganchlorat. Leitet man Salzsäure mit Luft gemischt in Kalilauge,' in der Mangansuperoxyd enthalten ist, so erhält man Kaliumchlorat.If you let z. B. hydrochloric acid act on manganese dioxide, so becomes: chlorine cleared, which then by the above procedure through the oxygen of the air below With the help of further manganese dioxide as a contact substance, oxidizes to chloric acid will. So there is malegan chlorate. One passes hydrochloric acid mixed in with air Potassium hydroxide, which contains manganese peroxide, gives potassium chlorate.

Der Vorteil dieses Verfahrens besteht demnach darin, daß der größte Teil des angewandten Chlors usw. in wertvolles Chlorat bzw. Hypochlorit verwandelt wird, während nach dem alten Verfahren nur "/e davon als Chlorat erhalten wurde.The advantage of this method is therefore that the greatest Part of the applied chlorine etc. is converted into valuable chlorate or hypochlorite while according to the old method only "/ e of it was obtained as chlorate.
