Das vorliegende Verfahren zur Darstellung von Borax kennzeichnet sich durch die Behandlung von Natriumchlorid und Natriumsulfat mit Ammoniumbiborat, wobei beide Körper sich so umsetzen, dafs einerseits Natriumbiborat, d. i. Borax, andererseits Chlorammonium bezw. Ammoniumsulfat entsteht.The present method of preparing borax is characterized by the treatment of sodium chloride and sodium sulfate with ammonium borate, both being Bodies convert themselves in such a way that, on the one hand, sodium biborate, i. i. Borax, on the other hand chlorammonium respectively Ammonium sulfate is formed.
Zur Ausführung des Verfahrens kann das Ammoniumbiborat entweder in Form des fertigen Salzes benutzt werden, z. B. indem man zwei Aequivalente Borsäure in Wasser löst oder suspendirt und durch Einleiten von Ammoniak in Ammoniumbiborat überführt und mit diesem Natriumchlorid oder Natriumsulfat in Lösung zersetzt; oder man erzeugt das Ammoniumbiborat in der zu zersetzenden Natriumsalzlösung selbst, z. B. indem man die Natriumsalzlösung ammoniakalisch macht und dann die Borsäure in Menge von zwei Aequivalenten zusetzt.To carry out the process, the ammonium biborate can either be in the form of finished salt can be used, e.g. B. by dissolving two equivalents of boric acid in water or suspended and converted into ammonium biborate by passing in ammonia and decomposed with this sodium chloride or sodium sulfate in solution; or you create it Ammonium biborate in the sodium salt solution to be decomposed itself, e.g. B. by using the The sodium salt solution makes ammoniacal, and then the boric acid in an amount of two equivalents clogs.
Als sehr zweckmäfsig hat sich folgendes Arbeitsverfahren erwiesen:The following working procedure has proven to be very useful:
In eine Lösung von Natriumchlorid oder Natriumsulfat bringt man zwei Aequivalente Borsäure und leitet trockenes Ammoniakgas in die Lösung ein.' Es erfolgt Erwärmung und Lösung der Borsäure, welche mit dem Ammoniak zu Ammoniumbiborat sich verbindet, welches letztere das Natriumsalz in Borax und Ammoniumchlorid bezw. Sulfat umsetzt. Bei Abkühlung krystallisirt zuerst der Borax aus, welcher auf geeignete Weise von der Lösung des Ammoniaksalzes getrennt wird.Two equivalents are placed in a solution of sodium chloride or sodium sulphate Boric acid and introduces dry ammonia gas into the solution. ' There is heating and Solution of boric acid, which combines with ammonia to form ammonium biborate, which the latter forms the sodium salt in borax and Ammonium chloride respectively. Converts sulfate. When it cools down, the borax crystallizes out first, which is separated in a suitable manner from the solution of the ammonia salt.
Durch stärkere Concentration der Lösung hat man es in der Hand, theilweise Ausscheidung von Borax bereits vor der Abkühlung zu erhalten.By stronger concentration of the solution one has it in hand, partly excretion of borax even before cooling.
Da der gebildete Borax zersetzend auf dies gebildete Ammonsalz einwirken kann, wenn auch wegen seiner geringen Alkalinität diese Einwirkung nur langsam sich vollzieht, so ist es zur Sicherung völliger Abscheidung rathsam, mit Ammoniaküberschufs zu arbeiten.Since the borax formed can have a decomposing effect on this ammonium salt formed, if also because of its low alkalinity this action takes place only slowly, so is To ensure complete separation, it is advisable to work with excess ammonia.
