Description

Verfahren zur Herstellung wässeriger Emulsionen hoher Konzentration Zusatz zum Patent 495 934 Das Verfahren des Hauptpatents ermöglicht die Herstellung wässeriger kolloidaler Lösungen bzw. Emulsionen unter Verwetldung kolloidaler Kieselsäure. Nach demselben werden die zu emulgierenden Stoffe in flüssiger oder gelöster Form mit getrockneter kolloidal gefällter Kieselsäure vermischt und in Wasser eingetragen. Nach eingehenden weiteren Untersuchungen hat sich ergeben, daß es unter Einhaltung bestimmter Verhältnisse möglich ist, in dieser Weise haltbare wässerige Emulsionen hoher Konzentration herzustellen, was bisher bei den meisten Stoffen mit erheblichen Schwierigkeiten verbunden war.Process for the preparation of aqueous emulsions of high concentration Addition to patent 495 934 The process of the main patent enables production aqueous colloidal solutions or emulsions using colloidal silica. According to the same, the substances to be emulsified are in liquid or dissolved form mixed with dried colloidally precipitated silica and added to water. After detailed further investigations it has been found that it is in compliance In certain proportions, aqueous emulsions which are stable in this way are possible to produce high concentration, which has so far been the case with most substances with considerable Difficulty was associated.

Zur Durchführung des Verfahrens können erfindungsgemäß auch andere anorganische Gele von hoher Adsorptionskraft, wie z. B. According to the invention, other methods can also be used to carry out the method inorganic gels of high adsorptive power, such as. B.

Aluminiumoxyd und Eisenoxyd, Verwendung finden. Diese festen Stoffe miissen sorgfältig von löslichen Salzen gereinigt, getrocknet und fein gemahlen sein. Den so vorbehandelten pulverförmigen Adsorbentien werden die zu emulgierenden fliissigen oder gelösten Stoffe in einer die Aufnahmefähigkeit des festen Adsorptionsstoffes nicht überschreitenden Menge zugesetzt und damit innig vermengt. Es ist zu diesem Zwecke vorteilhaft, die zu emulgierenden Stoffe in feinster Verteilung, z. B. als Spray, anzuwenden und etwa vorkommende Übersättigungen einzelner Teile durch inniges Mischen zu verhüten. Es hat sich gezeigt, daß ein örtlicher Überschuß hierbei gleichmäßig an die ärmeren Teilchen abgegeben wird.Aluminum oxide and iron oxide, find use. These solids must be carefully cleaned of soluble salts, dried and finely ground be. The powdery adsorbents pretreated in this way become those to be emulsified liquid or dissolved substances in one the absorption capacity of the solid adsorbent not exceeding the amount added and thus intimately mixed. It's about this Purposes advantageous, the substances to be emulsified in the finest distribution, eg. B. as Spray, apply and any oversaturation of individual parts by intimate Prevent mixing. It has been shown that a local excess here is uniform is given off to the poorer particles.

B e i s p i e l 1 500 g Al2 (SO4) 3 + IS H20 werden in 1 1 Wasser heiß gelöst, die Lösung sodann in 5 1 2prozentiges Ammoniakwasser eingetragen und der Niederschlag mit destilliertem Wasser mehrmals dekantiert und getrocknet. 100 g des so erhaltenen Produktes werden mit I5 g Erdnußöl innig vermengt und die erhaltene Mischung in 0,51 destilliertes Wasser eingetragen. Example 1 500 g Al2 (SO4) 3 + IS H20 are dissolved in 1 liter of water dissolved hot, the solution then entered into 5 1 2 percent ammonia water and the precipitate decanted several times with distilled water and dried. 100 g of the product thus obtained are intimately mixed with 15 g of peanut oil and the resulting product Mixture registered in 0.51 of distilled water.

Beispiel 2 500 g Fe2 CLb + 3 H20 werden in I 1 destilliertem Wasser heiß gelöst, die Lösung in 51 3prozentigesAmmoniakwasser eingetragen, gekocht, der Niederschlag mit destilliertem Wasser mehrmals dekantiert und getrocknet. Example 2 500 g of Fe2 CLb + 3 H20 are dissolved in I 1 of distilled water Dissolved hot, the solution added to 51 3 percent ammonia water, boiled, the Precipitate decanted several times with distilled water and dried.

IOOg des erhaltenen Produktes werden mit einer Lösung von 10 g Wachs in 30 g Perchloräthylen innig vermengt und die Mischung in ½ 1 t destilliertes Wasser eingetragen.100 g of the product obtained are mixed with a solution of 10 g of wax intimately mixed in 30 g of perchlorethylene and the mixture in ½ 1 t of distilled water registered.
