Verfahren zur Reinigung von durch teerige Bestandteile verunreinigten Ammoniumsalzen.
Sowohl bei der Reinigung von bei trockener Destillation von kohlenstoffhaltigem Material aller Art erhaltenen Ammoniumsalzen, insbesondere Ammoniumchlorid, Ammoniumsulfat, Ammoniumsulfit, als auch bei Ammoniumsulfat, welches durch Neutralisation von Abfallschwefelsäuren aller Art erhalten wird, zeigt sich der Übelstand, dass die erhaltenen Salze dunkel gefärbt sind, weil die teerigen Anteile sich ausserordentlich schwer entfernen lassen. Gleichzeitig haftet dem Produkte der Teergeruch an. Beide Ursachen machen das Produkt minderwertig.
Es hat sich gezeigt, dass es gelingt, diese fremden und schädigenden Bestandteile zu entfernen und die Salze in lichter Farbe rein und gut kristallisiert zu erhalten, wenn man die entsprechend verdünnten Lösungen der unreinen Salze mit Luft von jeweils zu bestimmender Temperatur eine durch Vorversuche festgestellte Zeit lang behandelt, sodann mit Ammoniak schwach übersättigt, hierauf durch reinen Sand, Bleicherden oder sonst ein Filtermaterial vorzugsweise von oben nach unten filtriert und zum Schlusse, falls noch nötig, das Filtrat so lange mit Wasserdampf behandelt, bis keinerlei Spuren teeriger Anteile mit dem letzteren übergehen.
Aus der so gereinigten Lösung gewinnt man die Salze in gewohnter Weise.

Process for the purification of ammonium salts contaminated by tarry components.
Both in the purification of ammonium salts obtained by dry distillation of carbonaceous material of all kinds, in particular ammonium chloride, ammonium sulfate, ammonium sulfite, and in the case of ammonium sulfate, which is obtained by neutralizing waste sulfuric acids of all kinds, the disadvantage is that the salts obtained are dark in color , because the tarry parts are extremely difficult to remove. At the same time, the tar smell adheres to the product. Both causes make the product inferior.
It has been shown that it is possible to remove these foreign and damaging components and to obtain the salts in a light color, pure and well crystallized, if the appropriately diluted solutions of the impure salts are mixed with air at a temperature to be determined for a time determined by preliminary tests treated for a long time, then slightly oversaturated with ammonia, then filtered through pure sand, bleaching earth or some other filter material, preferably from top to bottom, and finally, if necessary, the filtrate treated with steam until no traces of tarry components pass over with the latter .
The salts are obtained in the usual way from the solution purified in this way.
