Abstract
Description
des Herrn Herbert Lettko, 6500 Mainz-Drais,of Mr. Herbert Lettko, 6500 Mainz-Drais,
In den Obstanlagen 10 der Frau Marie Lettko, geb. Hofmann, 6500 Mainz-Drais, In den Obstanlagen 10 Verfahren zur Herstellung eines hochaktiven und hochvoluminösen Silberoxidkatalysators. In the orchards 10 of Mrs. Marie Lettko, née Hofmann, 6500 Mainz-Drais, In the orchards 10 method for producing a highly active and high-volume Silver oxide catalyst.
Die Erfindung betrifft ein Verfahren zur Herstellung eines heterogenen, hochvoluminösen, oligodynamischen, kolloidalen Silberkatalysators als Zusatzstoff eines Entgiftungspuders für die Entgiftung von chemischen Kampfstoffen.The invention relates to a method for producing a heterogeneous, high-volume, oligodynamic, colloidal silver catalyst as an additive a detox powder for the detoxification of chemical warfare agents.
Unter Katalyse versteht man die Erscheinung, daß chemische Reaktionen in ihrer Geschwindigkeit gesteigert werden durch Zusatz von Stoffen, die durch die Reaktion nicht verbraucht werden, also scheinbar durch ihre bloße Gegenwart wirken. Man bezeichnet diese Stoffe als Katalysatoren. Besonders augenfällig tritt die Wirkung der Katalysatoren bei solchen Reaktionen zutage, die in Abwesenheit des Katalysators überhaupt nicht mit merklicher Geschwindigkeit verlaufen.Catalysis is the phenomenon that chemical reactions can be increased in their speed by adding substances, which by the Reaction not to be consumed, so apparently by their mere Work in the present. These substances are known as catalysts. Particularly noticeable the effect of the catalysts becomes apparent in such reactions that in their absence of the catalyst do not proceed at any noticeable speed.
Da der Katalysator, um wirksam zu werden, mit den Molekülen, deren Reaktion er beschleunigen soll, in Berührung kommen muß, ist die katalytische Reaktionsbeschleunigung natürlich auch von der Menge des Katalysators abhängig. Denn je größer die Menge des Katalysators ist, umso mehr Moleküle des Substrats gelangen in der Zeiteinheit durch Diffusion mit ihm in Berührung.As the catalyst, in order to be effective, with the molecules whose The reaction to accelerate, must come into contact, is the catalytic acceleration of the reaction of course also dependent on the amount of catalyst. Because the bigger the crowd of the catalyst, the more molecules of the substrate arrive in the unit of time in contact with it by diffusion.
Im Falle der homogenen Katalyse ist die Zahl der Moleküle des Substrats, die in der Zeiteinheit mit dem Katalysator in Berührung kommen, von der Konzentration des Katalysators abhängig, IM FALLE DER "HETEROGENEN KATALYSE" VON SEINER OBERFLÄCHE.In the case of homogeneous catalysis, the number of molecules of the substrate that come into contact with the catalyst in the unit of time depends on the concentration depending on the catalyst, IN THE CASE OF "HETEROGENIC CATALYSIS" ON ITS SURFACE.
Ein gegebener Kontaktstoff ist daher umso wirksamer, je feiner bei gegebener Menge sein Verteilungsgrad ist.A given contact substance is therefore all the more effective, the finer at given amount is its degree of distribution.
Hierdurch erklärt sich die besonders starke katalytische Wirksamkeit kolloidaler Stoffe.This explains the particularly strong catalytic effectiveness colloidal substances.
Noch größer kann die katalytische Wirkung molekulardispers gelöster Stoffe sein, wenn diese ihrer chemischen Natur nach starke Reaktionsbeschleunigung zu bewirken vermögen.The catalytic effect can be even greater in molecularly dispersed form Substances if their chemical nature has a strong reaction acceleration able to effect.
Der Erfindung liegt die Aufgabe zugrunde, einen heterogenen, hochvoluminösen, kolloidalen Silberoxid-Katalysator auf Magnesiumbasis der eingangs erwähnten Art herzustellen, so daß ein Litergewicht von höchstens ca.The invention is based on the object of providing a heterogeneous, high-volume, colloidal silver oxide catalyst based on magnesium of the type mentioned at the beginning so that a liter weight of at most approx.
400 g oder darunter erreicht wird. Durch die Beaufschlagung von kolloidalem Silberoxid auf Magnesiumoxid wird eine Stärke von kolloidalem Silberoxid auf die Oberfläche des Magnesiumoxid von etwa 5,33 Ä erreicht.400 g or less is reached. By applying colloidal Silver oxide on magnesium oxide is a strength of colloidal silver oxide on the Surface of the magnesium oxide of about 5.33 Å reached.
Gelöst wird diese Aufgabe nach der Erfindung hinsichtlich dieses Verfahrens durch das Einbringen von Magnesiumoxidpulver mit einer Teilchenfeinheit nach einer negativen Mikronisierung in einer 2 Mol Silbernitratlösung. Hierbei wird Magnesiumoxid in mindestens 1.000-fachem Überschuß zugegeben.This object is achieved according to the invention with regard to this method by the introduction of magnesium oxide powder with a particle fineness after a negative micronization in a 2 mole silver nitrate solution. Here is magnesium oxide added in at least a 1,000-fold excess.
Es hat sich gezeigt, daß ein in dieser Weise hergestellter heterogener, kolloidaler Silberoxid-Katalysator als Zusatzstoff in dem nach Patent 28 28 735 angemeldeten Verfahren zur Herstellung einer hochaktiven und hochvoluminösen Calciumhypochlorit- bzw Chlorkalkmischung, in Verbindung mit Magnesiumoxid und kolloidaler Kieselsäure zur Herstellung eines Entgiftungspuders für die Dekontamination von chemischen Kampfstoffen, besonders die dekontaminierenden Eigenschaften verbessert bzw. erhöht.It has been shown that a heterogeneous, colloidal silver oxide catalyst as an additive in the patent 28 28 735 pending process for the production of a highly active and high-volume Calcium hypochlorite or chlorinated lime mixture, in connection with magnesium oxide and colloidal silica for the production of a detox powder for the decontamination of chemical warfare agents, especially the decontaminating properties are improved or increased.
