Description

Verfahren zur Herstellung von Salzsäure auf elektrolytischem Wege. Seit langem ist man bestrebt, das bei der Elektrolyse von Alkalichloridlösungen, z. B. Kochsalzlösungen, an der Anode entstehende Chlor in Salzsäure überzuführen. Bei a11 diesen Verfahren wird Chlor sekundär in einem von der Elektrolyse gesonderten Arbeitsgang zur Verwendung gebracht, indem man es über glühende Kohlen, Kontaktsubstanzen, Metallchloride usw. leitet oder in Mischungen mit Wasserstoff in Verbrennungskammern bringt usw. Diese Prozesse sind zum größten Teil meist, thermochemisch genommen, unwirtschaftlich.Process for the production of hydrochloric acid by electrolytic means. For a long time, efforts have been made to ensure that in the electrolysis of alkali chloride solutions, z. B. saline solutions to convert chlorine formed at the anode into hydrochloric acid. In a11 this process, chlorine is secondary in a separate from electrolysis Operation brought to use by placing it over glowing coals, contact substances, Metal chlorides, etc. conducts or in mixtures with hydrogen in combustion chambers brings etc. These processes are mostly, taken thermochemically, for the most part, uneconomical.

Weiter ist bekannt das Verfahren zur Darstellung von Salzsäure, bei dem Chlor in Gasform ohne künstliche Erwärmung über Braunkohle geleitet wird, oder indem man es durch eine Schicht Braunkohle streichen läßt; der Vorgang ist exothermisch und findet eine Erwärmung auf go bis ioo ° statt. Das Chlorgas kommt auch hier getrennt von dem Orte seiner Entstehung zur Anwendung.The process for the preparation of hydrochloric acid is also known the chlorine in gaseous form is passed over lignite without artificial heating, or by painting it through a layer of brown coal; the process is exothermic and there is a warming up to 100 °. The chlorine gas comes separately here as well from the place of its origin to the application.

Versuche haben nun gezeigt, daß, wenn man bei der Elektrolyse von Alkalichloridlösungen, z. B. von Kochsalzlösungen, in dem Anodenraum Braunkohle oder Torf suspendiert, sich aus dem entstehenden Chlorgas sofort Salzsäure in fast quantitativer Ausbeute bildet. Das Chlor wirkt in statu nascendi auf die Suspension von Braunkohle bzw. Torf ein und bildet Salzsäure; dagegen bildet sich, wenn Chlorgas sekundär in einem von der Elektrolyse getrennten Arbeitsgang in Wasser eingeleitet wird, in welchem Braunkohle bzw. Torf suspendiert sind, Salzsäure nur in geringer Menge.Experiments have now shown that if you are in the electrolysis of Alkali chloride solutions, e.g. B. of saline solutions, lignite in the anode compartment or suspended peat, the resulting chlorine gas immediately turns into hydrochloric acid quantitative yield forms. The chlorine acts on the suspension in statu nascendi from lignite or peat and forms hydrochloric acid; however, forms when chlorine gas secondarily introduced into water in a separate operation from the electrolysis in which lignite or peat are suspended, hydrochloric acid is only slightly lower Lot.

Das vorstehende Verfahren erlaubt also die Gewinnung von Salzsäure und Alkalilauge, im speziellen Falle Natronlauge, aus Kochsalz in einem Arbeitsgange. Es können die in der Industrie bekannten elektrolytischen Chloralkaliprozesse, wie das Diaphragmen-, Quecksilber-und Glockenverfahren, nach dem obigen Verfahren modifiziert werden. Es können ferner ohne weiteres alle Alkalichloride, wie Caliumchlorid, Calciumchlorid usw. angewandt werden.The above process thus allows hydrochloric acid to be obtained and alkali, in the special case caustic soda, from table salt in one operation. The electrolytic chloralkali processes known in the industry, such as the diaphragm, mercury and bell processes, modified according to the above process will. Furthermore, all alkali chlorides, such as potassium chloride, calcium chloride, can be used without further ado etc. can be applied.
