Description

Verfahren zur Herstellung von imidodisulfonsaurem Ammoniak Das imidodisulfonsaure Ammonium, welches die Formel NH, NH (S03 NH4), hat, wird nach Literaturangaben theoretisch aus Schwefelsäureanhydrid (SO,) und Ammoniak unter Ausschluß von Wasser erhalten lvgl. H o f m a n n, Lehrbuch der anorg. Chemie [19r9]. S. z75).Process for the production of imidodisulfonic acid ammonia The imidodisulfonic acid Ammonium, which has the formula NH, NH (S03 NH4), is theoretical according to the literature obtained from sulfuric anhydride (SO,) and ammonia with exclusion of water lv. H o f m a n n, textbook from anorg. Chemistry [19r9]. P. Z75).

Eine betriebsmäßige Herstellung dieses Salzes ist bis dahin noch nicht gelungen, weil die hohen Kosten der Herstellung eine Verwendungsmöglichkeit ausschließen und für wissenschaftliche Zwecke ein Bedarf für dieses Produkt nicht vorlag.A commercial production of this salt is not yet possible succeeded because the high costs of production exclude a possible use and there was no need for this product for scientific purposes.

Andererseits ist dieses Salz infolge seines hohen Stickstoffgehaltes und seiner sonstigen vorzüglichen Eigenschaften ein erstklassiges Düngesalz.On the other hand, this salt is due to its high nitrogen content and its other excellent properties a first-class fertilizer salt.

Die vorliegende Erfindung betrifft ein Verfahren, mittels dessen es gelingt, dieses Salz auf billigem Wege herzustellen, so daß es der Volkswirtschaft auch in ökonomisch befriedigender Weise zugeführt werden kann.The present invention relates to a method by means of which it succeeds in producing this salt cheaply, so that it can be used by the national economy can also be supplied in an economically satisfactory manner.

Das Verfahren wird in der Weise durchgeführt, daß wasserfreies Ammoniak mit w asserfreiem Schwefeloxyd in praktisch molekularen Verhältnissen bei einer Temperatur von etwa 12o° mittels durch hochgespannten Gleichstrom aus der bei der Reaktion anwesenden Luft erzeugter Stickoxyde als Katalysatoren in Reaktion gebracht wird. Nachstehend ist ein zahlenmäßig belegtes Ausführungsbeispiel des Verfahrens gegeben.The process is carried out in such a way that anhydrous ammonia with anhydrous sulfur oxide in practically molecular proportions for one Temperature of about 12o ° by means of high voltage direct current from the at the Reaction present air generated nitrogen oxides brought into reaction as catalysts will. Below is a numerical embodiment of the method given.

Innerhalb eines Behälters wird in an sich bekannter Weise ein hochgespannter Gleichstrom erzeugt. Unter dem Einfluß dieses hochgespannten Gleichstromes bilden sich aus der Luft Stickoxyde. In den gleichen Behälter wird wasserfreies Ammoniak, vorzugsweise in molekularem Verhältnis mit wasserfreiem Schwefeloxyd eingeführt. Unter dem Einfluß der Stickoxyde als Katalysatoren entsteht bei Aufrechterhaltung einer Reaktionstemperatur von etwa rao° das imidodisulfonsaure Salz.Inside a container is a highly tensioned one in a manner known per se Generated direct current. Form under the influence of this high voltage direct current nitrogen oxides emerge from the air. In the same container is anhydrous ammonia, preferably introduced in a molecular ratio with anhydrous sulfur oxide. Under the influence of nitrogen oxides as catalysts, it arises when maintained a reaction temperature of about rao ° the imidodisulfonic acid salt.
