Description

Herstellung von Fluor Zur Darstellung von Fluor wird geschmolzenes Alkalibi- oder -polyfluorid der Elektrolyse unterworfen. Es ist hierbei erforderlich, daß das verwandte Alkalibi- oder -polyfluorid vollkommen wasserfrei ist, da andernfalls die Elektrolyse versagt.Production of fluorine In order to produce fluorine, molten material is used Alkali bi- or polyfluoride subjected to electrolysis. It is necessary here, that the related alkali bi- or polyfluoride is completely anhydrous, otherwise the electrolysis fails.

Das als Ausgangsmaterial für die Elektrolyse dienende Alkalibi- oder -polyfluorid mußte in außerordentlich umständlicher Weise durch tagelanges Trocknen entwässert werden.The alkali metal or alkali metal used as starting material for the electrolysis -polyfluoride had to be dried for days in an extraordinarily laborious manner be drained.

Es wurde nun gefunden, daß sich vollkommen wasserfreies Alkalibi- oder -polyfluorid dadurch herstellen läßt, daß man das feste oder geschmolzene Salz mit Fluor behandelt. Das Fluor reagiert mit dem vorhandenen Wasser bekanntlich unter sofortiger Bildung von Flußsäure, die sich mit den Fluoriden. unter Bildung von Alkalipolyfluorid vereinigt, Beispiel too g Kaliumbifluorid, das i °% Wasser enthält, wird mit Fluorgas behandelt. Mach einer Stunde ist das Wasser vollständig zersetzt.It has now been found that completely anhydrous alkali or polyfluoride can be prepared by the fact that the solid or molten salt treated with fluorine. It is well known that the fluorine underreacts with the water present immediate formation of hydrofluoric acid, which reacts with the fluorides. with the formation of Alkali polyfluoride combined, example too g potassium bifluoride, which contains i °% water, is treated with fluorine gas. The water is completely decomposed after an hour.
