Description

Verfahren zur Erhöhung der Löslichkeit von Bleichlorid in wäßrigen Lösungen von Alkaliacetat Es ist bekannt, daß Bleichlorid sich in N V ' ßriger Natriumacetatl** os ung , löst. Diese Lösungen enthalten jedoch nicht mehr als 5 0j0 Bleichlorid.A process for increasing the solubility of lead chloride in aqueous solutions of alkali metal acetate It is known that lead chloride in NV 'ßriger Natriumacetatl ** os ung dissolves. However, these solutions do not contain more than 50% lead chloride.

Der Zweck der vorliegenden Erfindung ist, eine Lösung herzustellen, welche eine weit größere Menge von Bleichlorid enthält, als es bisher möglich war, und dies durch ein äußert einfaches Verfahren zu erreichen. Dies gelingt, wenn gemäß der Erfindung Alkaliacetatlösungen geringe Mengen von Säuren zugesetzt «-erden, die lösliche Bleisalze bilden. Die Säure wird am besten zugesetzt, nachdem die Mischung von Bleichlorid und Alkaliacetat auf etwa 8o° C erhitzt worden ist. Dann wird stets eine klare Lösung erhalten.The purpose of the present invention is to produce a solution which contains a far greater amount of lead chloride than was previously possible, and to achieve this through an extremely simple process. This succeeds if according to small amounts of acids added to the invention in alkali acetate solutions «-erden, which form soluble lead salts. The acid is best added after the mixture has been heated to about 80 ° C by lead chloride and alkali acetate. Then will always get a clear solution.

Indefinite i 1 The result is that the small amount of acid added to the solvent greatly increases the dissolving power of the lead chloride. The effect is particularly beneficial with nitric acid.

Die Lösung kann in allen solchen Fällen verwendet werden, wo Bleichlorid als Reagens Verwendung finden soll, besonders aber bei der Behandlung von Ammoniaklaugen zur Wiedergewinnung von Katechinen.The solution can be used in all cases where lead chloride to find use as a reagent, but especially in the treatment of ammonia liquors for the recovery of catechins.
