Description

Herstellung von Salpetersäure. Bei dem Verfahren nach dem Hauptpatent wird die Oxydations- bzw. Kondensationswirkung des Ozons im elektrischen Felde zur Beschleunigung der Reaktion benutzt, durch die in einem Gemisch von nitrosen Gasen mit nebelförmiger dünner Salpetersäure unter gleichzeitiger Zuhilfenahme von (beschränkten Mengen) Wasserdampf die Bildung von hochgradiger Salpetersäure bewirkt wird.Production of nitric acid. In the process according to the main patent the oxidation or condensation effect of the ozone in the electric field becomes Accelerating the reaction used by being in a mixture of nitrous gases with thin nitric acid in the form of a mist with the simultaneous use of (restricted Quantities) water vapor causes the formation of high-grade nitric acid.

Es hat sich gezeigt, daß man an Stelle von Wasserdampf auch Wasser in fein verteilter Form oder in Form verdünnter Säuren anwenden kann. Ein besonderer technischer Vorteil liegt in der Verwendung verdünnter Salpeter- und Schwefelsäure, da man an anderen Stellen anfallende dünne Salpetersäure, die ohne weitere Konzentration einer nutzbringenden technischen Verwendung nicht fähig ist, in solche von höherer Konzentration überführen kann, wenn man diese verdünnte Säure in entsprechender Menge statt des Wasserdampfes dem Gasgemisch in geeigneter Verteilung zuführt. Man erhält dabei aus den Stickstoff - Sauerstoffverbindungen des Gasnebelgemisches unter Ausnutzung eines Teiles des Wassers der zugeführten verdünnten Säure eine Säure höherer lfönzentration, die sich ohne weiteres für viele technische Zwecke, z. B. als Zusatz zur Nitriersäure, wieder verwenden läßt, ohne daß eine Hochkonzentration durch Destillation not-«-endig ist.It has been shown that instead of water vapor one can also use water can be used in finely divided form or in the form of diluted acids. A special technical advantage lies in the use of dilute nitric and sulfuric acid, because thin nitric acid accumulating in other places, without further concentration is incapable of a useful technical application, in those of a higher level Concentration can be converted, if this dilute acid in the appropriate Amount instead of the water vapor supplies the gas mixture in a suitable distribution. Man receives from the nitrogen - oxygen compounds of the gas mist mixture Utilization of part of the water of the supplied dilute acid an acid higher oil concentration, which can easily be used for many technical purposes, e.g. B. as an additive to the nitrating acid, can be re-used without a high concentration by distillation not - «- is finished.

In gleicher Weise kann man anstatt der dünnen Salpetersäure z. B. verdünnte Schwefelsäure dem Gasgemisch zuführen und so eine technisch verwendbare Mischsäure erzielen.In the same way you can use instead of the thin nitric acid z. B. Add dilute sulfuric acid to the gas mixture and thus a technically usable one Achieve mixed acid.
