Emulsion, insbesondere für Gerbereizwecke Es wurde gefunden, daß frisch gefällte Metallhydroxyde Fette oder Öle dazu befähigen, mit Wasser haltbare Emulsionen zu bilden.Emulsion, especially for tanning purposes. It has been found to be fresh Precipitated metal hydroxides enable fats or oils to form emulsions that are durable with water to build.

Weiterhin hat sich gezeigt, daß diese Emulsionen in der Gerberei, und zwar beim Abölen oder im Fettlicker mit. Vorteil anwendbar sind, und zwar vor, während oder nach der Gerbung. Durch die Verwendung dieser Metallhydroxyde vor der Gerbung wird beispieleweise eine Übergerbung des Narbens verhindert. Gegenüber den sonst zur Verwendung gelangenden Seifen oder sulfurierten Ölen haben die hier beschriebenen Emulsionen den Vorteil, daß sie in ihrer Wirksamkeit durch Säuren nicht gestört werden.Furthermore, it has been shown that these emulsions in the tannery, namely when removing oil or in the fat liquor with. Advantage are applicable, namely before, during or after tanning. By using these metal hydroxides before For example, tanning prevents over-tanning of the grain. Compared to the Soaps or sulfurized oils otherwise used have those described here Emulsions have the advantage that their effectiveness is not impaired by acids will.

Als Metallhydroxyd hat sich frisch gefälltes, feuchtes Aluminiumhydroxyd als besonders brauchbar erwiesen.Freshly precipitated, moist aluminum hydroxide has proven to be the metal hydroxide Proven to be particularly useful.

Zweckmäßig ist auch die Verwendung von Harnstoff bei Anwendung von Emulsionen in der Gerberei, weil dadurch die Färbung günstig beeinflußt wird.It is also expedient to use urea when using Emulsions in the tannery because they have a beneficial effect on the coloration.

Beispiele. 1. 25 Teile Klauenöl, 25 Teile Harnstoff und 5 Teile Aluminiumhydroxyd in 45 Teilen Wasser ergeben die gewünschte Emulsion des Aluminiumhydroxyds, die im Bedarfsfalle, z. B. für Gerbereizwecke, noch einen entsprechenden Wasserzusatz erhält.Examples. 1. 25 parts of foot oil, 25 parts of urea and 5 parts of aluminum hydroxide in 45 parts of water give the desired emulsion of aluminum hydroxide, the if necessary, e.g. B. for tannery purposes, nor an appropriate water addition receives.

2. 35 Teile Klauenöl, 5 Teile Aluminiumhydroxyd und 6o Teile Wasser werden zu einer Emulsion verarbeitet.2. 35 parts of foot oil, 5 parts of aluminum hydroxide and 60 parts of water are processed into an emulsion.

3. Aus 22 Teilen Klauenöl, 3 Teilen Chromhydroxyd und 75 Teilen Wasser wird die Emulsion hergestellt.3. From 22 parts of nipple oil, 3 parts of chromium hydroxide and 75 parts of water the emulsion is made.

4. 4o Teile Klauenöl, 4 Teile Eisenhydroxyd und 56 Teile Wasser werden emulgiert.4. 40 parts of neat foot oil, 4 parts of iron hydroxide and 56 parts of water emulsified.

5. Eine Emulsion aus 1,25 Teilen Klauenöl, 1,25 Teilen Harnstoff, o,25 Teilen Aluminiumhydroxyd und 2,25 Teilen Wasser wird mit 95 Teilen einer Appretur, die ihrerseits aus io Teilen Stärke, io Teilen Bittersalz, i Teil Seife und 79 Teilen Wasser besteht, innig gemischt. Diese Mischung wird in der üblichen Weise zum Appretieren von Weißwaren verwendet.5. An emulsion of 1.25 parts of nipple oil, 1.25 parts of urea, 0.25 parts of aluminum hydroxide and 2.25 parts of water is mixed with 95 parts of a finish, which in turn consists of 10 parts starch, 10 parts Epsom salt, 1 part soap and There are 79 parts of water, intimately mixed. This mixture is used in the usual way for finishing white goods.
