Description

Verfahren zur Abscheidung von Chlorbarium aus Lösungen. Es ist bekannt, daß man Chlorbarium aus Lösungen durch Chlorwasserstoff abscheiden kann, indem man die Lösungen entweder mit wäßriger Salzsäure versetzt oder Salzsäuregase einleitet. Verwendet man nun für diesen Zweck technische Salzsäuregase, wie man sie z. B. bei der Sulfatherstellung aus.Kochsalz und Schwefelsäure erhält, so erhält man ein Chlorbarium, welches stets durch Bariumsulfat verunreinigt ist. Es liegt dieses daran, daß die technischen Salzsäuregase durch Schwefelsäure und schweflige Säure verunreinigt sind. Die Schwefelsäure bildet naturgemäß ohne weiteres Bariumsulfat. Aber auch die schweflige Säure gibt zur Bildung von Bariumsulfat Veranlassung, und zwar aus folgendem Grunde: Die von den Sulfatöfen kommenden Salzsäuregase sind stets durch Luft erheblich verdünnt, so daß der Luftsauerstoff beim Einleiten der Gase in die Chlorbariumlösung intermediär entstehendes Bariumsulfit zu Bariumsulfat oxydiert.Process for separating chlorobarium from solutions. It is known, that one can separate chlorobarium from solutions by means of hydrogen chloride by either aqueous hydrochloric acid is added to the solutions or hydrochloric acid gases are passed in. If you now use technical hydrochloric acid gases for this purpose, as they are z. B. at the production of sulphates from table salt and sulfuric acid, a chlorine barium is obtained, which is always contaminated with barium sulfate. This is because the technical hydrochloric acid gases contaminated by sulfuric acid and sulphurous acid are. The sulfuric acid naturally forms barium sulfate without further ado. But also the sulphurous acid gives rise to the formation of barium sulphate, namely from for the following reason: The hydrochloric acid gases coming from the sulphate ovens are always through Air is considerably diluted, so that the atmospheric oxygen when the gases are introduced into the Chlorbarium solution intermediate barium sulfite is oxidized to barium sulfate.

Es wurde nun gefunden, daß man die geschilderten Übelstände vermeiden kann, wenn man die salzsäurehaltigen Gase, bevor sie zur Einwirkung auf die Chlorbariumlösung gebracht werden, einer Behandlung mit großoberflächigen Stoffen, z. B. aktive Kohle, oder konzentrierter Salzsäure, welche Chlorbarium in fester Form als Suspension enthält, oder aber der Einwirkung beider Mittel unterwirft. Beim Arbeiten mit großoberflächigen Stoffen hat es sich ferner als zweckmäßig erwiesen, die zu behandelnden Gase, bevor man sie der Einwirkung der großoberflächigen Stoffe aussetzt, mit konzentrierter Schwefelsäure zu waschen.It has now been found that the evils described can be avoided can if you remove the hydrochloric acid gases before they act on the chlorobarium solution be brought, a treatment with large surface substances, such. B. active coal, or concentrated hydrochloric acid, which contains chlorbarium in solid form as a suspension contains, or is subject to the action of both agents. When working with large surface areas Substances, it has also proven to be useful, the gases to be treated before they are exposed to the action of large-surface substances, with concentrated Wash sulfuric acid.
