PATENTAMT.PATENT OFFICE.
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Thorhydrat in kolloidalem Zustande. .The present invention relates to a method for producing thorhydrate in colloidal condition. .
Es wird ausgeführt, indem man zu Thoriumsalzen, z. B. Thoriumnitrat oder deren Gemengen, in fester Form oder in wässeriger Lösung die äquivalente Menge Ammoniak bzw. Alkali hinzusetzt.It is carried out by adding to thorium salts, e.g. B. Thorium nitrate or their mixtures, in solid form or in aqueous solution, the equivalent amount of ammonia or alkali is added.
Ein unter dieser Bedingung, also unter ίο Vermeidung eines Überschusses an Alkali hergestelltes Hydrat geht bei der Erwärmung in das Kolloid über.One produced under this condition, i.e. under ίο avoiding an excess of alkali Hydrate changes into the colloid when heated.
Ist bei der Herstellung des Hydrates ein Überschuß an Alkali bzw. Ammoniak vorhanden, so zeigt sich, wie der Versuch lehrt, daß das durch Ausfällung erhaltene Hydrat sich beim Erwärmen nicht verändert und sich nicht in Kolloid umwandelt.If there is an excess of alkali or ammonia in the production of the hydrate, so it is shown, as the experiment teaches, that the hydrate obtained by precipitation does not change when heated and does not turn into colloid.
Bei Ausführung des Verfahrens wird Ammoniak bzw. Alkali in solchen Mengen zugesetzt, daß kein Thorsalz mehr in Lösung bleibt. Nach erfolgtem Auswaschen wird das Hydrat erwärmt, wobei die Umsetzung in den kolloidalen Zustand vor sich geht. Es empfiehlt sich, das Hydrat in feuchtem Zustände zu verwenden. Die Erwärmung kann am einfachsten auf einem Wasserbad durchgeführt werden. Schon bei etwa 70 ° tritt vollständige Umsetzung des normalen Hydrates in das Kolloid (Sol) ein, wobei das feste Hydrat in eine schön opalisierende Lösung übergeht.When carrying out the process, ammonia or alkali is added in such amounts that no more salt remains in solution. After washing has taken place, the hydrate is heated, and the reaction takes place in the colloidal state is going on. It is best to hydrate the hydrate in moist conditions to use. The easiest way to warm up is on a water bath will. Complete conversion of the normal hydrate into the colloid (sol) already occurs at around 70 °, whereby the solid hydrate turns into a nicely opalescent solution.
Diese Lösung kann in jeder beliebigen Konzentration erhalten werden und ergibt bei vollständigem Eindampfen eine in Wasser lösliche hornartige Masse.This solution can be obtained and yields in any concentration with complete evaporation a horn-like mass soluble in water.
