Description

Verfahren zur Gewinnung von Brom Die Bromgewinnung wird in der Technik im allgemeinen derart durchgeführt, daß aus den Bromsalze enthaltenden Lösungen das Brom durch Chlor in Freiheit ;gesetzt, durch Erhitzen der Lösung abgetrieben und durch Kondensation ,der Dämpfe flüssig miedergeschlagen wird.Process for the production of bromine The bromine production is in the technology generally carried out in such a way that from the solutions containing bromine salts the bromine released by chlorine; set, driven off by heating the solution and by condensation, which turns vapors into a liquid.

Als Ausgangsmaterial 'dienten bisher die in den Betrieben der Kalisalz- und Chlorkaliumgewinnung anfallenden, an Brom sich allmählich anreichernden kalten Mutterläu-;gen, aus denen dann nach Anheizen auf etwa I I o° in den Bromtürmen das Brom: ausgetrieben wird. Bei :dieser Arbeitsweise werden mit den durch Eindampfen oder Ab- kühlender Salzlösungen gewonnenen chloridischen Salzen erhebliche Mengen Brom mit abgeschieden, :gehen also verloren.As the starting material were 'previously incurred in the premises of the Kalisalz- and potassium chloride extraction, bromine gradually accumulate cold Mutterläu-; gen, from which then the bromine by heating to about II o ° in the Bromtürmen: is expelled. In: this method are compared with the cooling by evaporation or waste brines gained chloride salts with significant amounts of bromine deposited: go therefore lost.

Es wurde nun gefunden, daß sich besondere Vorteile ergeben, wenn das Brom aus den heißen Lösungen vor ihrer Abkühlung und vor Kristallisation der bei der Abkühlung ausfallenden Salze gewonnen wird. Erstens wird so die Bromausbeute um, die sich sonst mit den Chloriden ausscheidende Brommenge erhöht, zweitens fällt das erneute Anheizen der zu entbromenden kalten Mutterlauge fort, es ergibt sich also eine Wärmeersparnis, :drittens sind die nunmehr aus den entbromten heißen Lösungen gewonnenen Salze ohne weitere besondere Behandlung praktisch frei von Brom, was für manche technische Zwecke, insbesondere für die Elektrolyse .der Alkalichloride, gefordert wird'. Die neue Arbeitsweise bedeutet also einen dreifachen technischen Fortschritt.It has now been found that there are particular advantages when the Bromine from the hot solutions before their cooling and before the crystallization of the the salts precipitating during cooling is obtained. First, so will the bromine yield um, the amount of bromine that otherwise precipitates out with the chlorides increases, and secondly, it falls the renewed heating of the cold mother liquor to be debrominated continues, it results thus a heat saving: thirdly, they are now from the debrominated hot solutions obtained salts practically free of bromine, which without further special treatment for some technical purposes, especially for the electrolysis of alkali chlorides, is required '. The new way of working means a threefold technical one Progress.

Das Austreiben des Broms kann man durch Einleiten von Luft fördern.The expulsion of the bromine can be promoted by introducing air.

Das Verfahren ist auch anwendbar auf die für - die Speisesalzgewinnung benutzten heißen Salzlösungen, deren Bromgehalt eine Gewinnung lohnt, wobei. die entbromten Laugen, welche Iden Bromturm verlassen, zwecks Gewinnung des Speisesalzes verdampft werden.The process can also be used for - the production of table salt used hot salt solutions, the bromine content of which is worth extracting, whereby. the debrominated lyes that leave Iden Bromturm for the purpose of extracting the table salt be vaporized.
