Description

Herstellung einer hochaktiven Adsorptions- und Bleicherde Es ist bekannt, die Entfärbungskraft von Rohbleicherden durch Behandeln mit Säuren zu crhöhen, indem man die fein verteilte Rohbleicherde entweder in trockenem Zustande oder in Form eines Schlammes der Säure aussetzt.Production of a highly active adsorption and bleaching earth It is known to increase the decolorizing power of raw bleaching earths by treating them with acids by the finely divided raw bleaching earth either in the dry state or in the form exposing a sludge to acid.

Nach diesem Verfahren werden die hochaktiven Bleicherden in feinst gemahlenem Zustande gewonnen oder aber in Form von Körnern, die leicht zerfallen. Für gewisse technische Zwecke wird jedoch körnige Bleicherde von hoher mechanischer Festigkeit verlangt, die sie auch bei Benetzung mit Flüssigkeiten beibehält. After this process, the highly active bleaching earths are made into the finest obtained in a ground state or in the form of grains that easily disintegrate. For certain technical purposes, however, granular fuller's earth is highly mechanical Requires strength that it retains even when wetted with liquids.

Es wurde gefunden, daß durch geeignete Vorbehandlung der Roherde diese in eine Form zu bringen ist, bei der die Masse einerseits durchlässig genug ist, um eine vollkommene Aktivierung mit Säure zu ermöglichen, ohne aber andererseits dabei zu zerfallen. It has been found that by suitable pretreatment of the raw earth this is to be brought into a form in which the mass is on the one hand permeable enough is to allow a complete activation with acid, but without on the other hand to disintegrate in the process.

Ein geeigneter Weg ist die Vorbehandlung der mit RVasser zu einem Schlamm gebrachten Roherde mit Wasserglas. Nach dem Wasserglaszusatz wird teilweise oder ganz getrocknet, gegebenenfalls schon jetzt auf die gewünschte Körnung gebracht und sodann mit Siiure aktiviert. A suitable way is to pre-treat the with RVasser to one Mud brought raw earth with water glass. After adding the water glass, it becomes partially or completely dried, if necessary already brought to the desired grain size and then activated with acid.

An Stelle von Wasserglas können auch Alkalien zur Verwendung kommen. Diese bilden dann mit leicht zersetzlichen Silikatanteilen auch Wasserglas, so daß die gleiche Wirkung erzielt wird. Alkalis can also be used instead of water glass. These then also form water glass with easily decomposable silicate components, so that the same effect is achieved.

Beispiel 100 Teile einer leicht zerfallenden Rohbleicherde werden je nach deren Wassergehalt mit 80 bis 150 Teilen Wasser in Schlamm übergeführt. Diesem werden unter Rühren 30 Teile Wasserglas von 28° Bé zugesetzt. Example 100 parts of an easily disintegrating raw bleaching earth depending on their water content converted into sludge with 80 to 150 parts of water. 30 parts of water glass at 28 ° Bé are added to this with stirring.

Sodann wird eingedampft. Nunmehr wird nach dem Zusatz von So bis So Teilen Salzsäure erhitzt und nach 1@ bis stündiger Einwirkung mit Wasser gewaschen und getrocknet.It is then evaporated. Now after the addition of So to So Parts of hydrochloric acid are heated and washed with water after 1 to 1 hour exposure and dried.
