Die Halogen haltende Flüssigkeit oder, falls ein Halogen haltender fester Körper vorliegt, seine möglichst concentrirte Lösung wird mit Salpetersäure oder einem Salpetersäure oder salpetrige Säure entwickelnden Körper erwärmt, deren Menge sich nach der Menge der Flüssigkeit und ihrem Gehalt an Halogen richtet und durch Versuch festgestellt wird. Man setzt dann organische Körper hinzu, welche unter den gegebenen Umständen leicht flüchtige Halogenverbindungen bilden, als Methyl- und Aethylalkohol oder Mischungen, welche diese Körper enthalten. Von der Gröfse des Zusatzes gilt dasselbe wie von dem der Salpetersäure. Die Halogene entweichen bei der eintretenden Reaction, welche sich durch Bildung von salpetrigen und aldehydartig riechenden Dämpfen anzeigt. Man unterstützt die Reaction durch Erwärmen und beendet sie durch längeres Kochen. In dem Rückstand sind Essigsäure und andere homologe Säuren nicht nachzuweisen. Sämmtliche Halogenverbindungen werden auf diese Weise leicht angegriffen und vom Halogen befreit, mit Ausnahme der überchlorsauren Salze, welche indessen in der sauren Lauge derart ihre Schwerlöslichkeit verlieren, dafs sie durch Umkrystallisiren getrennt werden können.The halogen-containing liquid or, if a halogen-containing solid is present, its solution, as concentrated as possible, is made with nitric acid or a nitric acid or Nitrous acid-developing body warms up, the amount of which depends on the amount of liquid and their halogen content and is determined by experiment. One sets then organic bodies are added, which are easily volatile under the given circumstances Form halogen compounds, as methyl and ethyl alcohol or mixtures, which these Body included. The same applies to the size of the addition as to that of nitric acid. The halogens escape when the reaction occurs, which is formed by formation of nitrous and aldehyde-like smelling vapors. You support the reaction by heating and finished by boiling for a long time. There is acetic acid in the residue and other homologous acids cannot be detected. All halogen compounds are easily attacked in this way and freed from halogen, with the exception of the superchloric acid salts, which are in the acidic liquor lose their insolubility to such an extent that they are separated by recrystallization can be.
Beispiel: 1. Zu dem Gemisch von 300 kg Salpeter von 1 pCt. Chlornatrium und 330 kg Schwefelsäure von 6o° B. läfst man, sobald die Destillation beginnt, durch ein im Deckel eingekittetes schwanenhalsartiges Eisenrohr so schnell, als die hierbei eintretende Reaction es gestattet, Spiritus zulaufen, bis das Destillat sich chlorfrei erweist. Es genügen in der Regel 7 kg Spiritus von 92° Tralles. Sodann wird die Vorlage gewechselt. Man erhält in der gut zu kühlenden ersten Vorlage eine geringe Menge an Untersalpetersäure und chlorreicher Salpetersäure, während die übrige, in der zweiten Vorlage aufgefangene Salpetersäure frei von Chlor ist.Example: 1. To the mixture of 300 kg saltpeter of 1 pCt. Sodium chloride and 330 kg As soon as the distillation begins, sulfuric acid of 60 ° B. is passed through a cement cemented into the lid Gooseneck-like iron pipe as quickly as the reaction which occurs here allowed to run in spirit until the distillate proves to be chlorine-free. It suffices in the Usually 7 kg of spirit from 92 ° Tralles. Then the template is changed. You get in the first template, which is easy to cool, contains a small amount of subnitric acid and chlorine-rich Nitric acid, while the rest of the nitric acid collected in the second receiver is free of chlorine.
2. 100 kg Natriumsalpeter von 0,3 pCt. Chlornatrium in 80 kg Wasser gelöst, mit 5 kg technischer Salpetersäure vom specifischen Gewicht 1,4 gekocht und dann mit 5 kg Spiritus von 92° Tralles versetzt, längere Zeit schliefslich gekocht, erweisen sich als halogenfrei.2. 100 kg sodium nitrate of 0.3 pCt. Sodium chloride dissolved in 80 kg of water, with 5 kg of technical nitric acid of specific gravity 1.4 cooked and then mixed with 5 kg of spirit of 92 ° Tralles, for a long time finally cooked, turn out to be halogen-free.
3. Zu dem Gemisch von 300 kg Salpeter von ι pCt. Chlornatrium und 330 kg Schwefelsäure von 6o° B. läfst man, sobald die Destillation beginnt, durch ein im Deckel eingekittetes schwanenhalsartiges Eisenrohr so schnell, als die hierbei eintretende Reaction es gestattet, Methylalkohol zulaufen, bis das Destillat sich chlorfrei erweist. Es genügen in der Regel ι ο kg Holzgeist von 88° Tralles. Man erhält in der gut zu kühlenden ersten Vorlage eine geringe Menge an Untersalpetersäure und chlorreicher Salpetersäure, während die übrige, in der zweiten Vorlage aufgefangene Salpetersäure frei von Chlor ist.3. To the mixture of 300 kg saltpetre from ι pCt. Sodium chloride and 330 kg sulfuric acid from 60 ° B., as soon as the distillation begins, it is passed through a cement cemented into the lid gooseneck-like iron pipe as quickly as the resulting reaction allows, Add methyl alcohol until the distillate is chlorine-free. It suffices in the Usually ι ο kg wood spirit from 88 ° Tralles. The first template, which is easy to cool, is obtained a small amount of subnitric acid and chlorine-rich nitric acid, while the rest, nitric acid collected in the second receiver is free of chlorine.
4. 100 kg Natriumsalpeter von 0,3 pCt. Chlornatrium in 80 kg Wasser gelöst, mit 5 kg technischer Salpetersäure vom specifischen Gewicht 1,4 gekocht und dann mit 7 bis 8 kg Holzgeist von 88° Tralles versetzt, längere Zeit schliefslich gekocht, erweisen sich als halogenfrei. 4. 100 kg sodium nitrate of 0.3 pCt. Sodium chloride dissolved in 80 kg of water, with 5 kg of technical nitric acid of specific gravity 1.4 cooked and then mixed with 7 to 8 kg of wood spirit from 88 ° Tralles, for a long time finally cooked, turn out to be halogen-free.
