Description

Verfahren zur Herstellung hochstabiler Emulsionen Die gebräuchlichsten Mittel zur Herstellung und Stabilisierung von Emulsionen sind die Oleate,wie Natrium- und Kaliumoleat, neutrale oder alkalische Gele, z. B. Gummi arabikum, alkalisches Stärkegel, Tragantschleim, die Caseine, ferner Türkischrotöl u. a.Process for the preparation of highly stable emulsions The most common Means for the production and stabilization of emulsions are the oleates, such as sodium and potassium oleate, neutral or alkaline gels, e.g. B. gum arabic, alkaline Starch gel, tragacanth slime, caseins, and Turkish red oil and others.

Der Zweck der Anwendung dieser Stoffe besteht nicht nur darin, den Emulgierungsvorgang, also die feine Verteilung des zu emulgierenden Stoffes herbeizuführen, sondern vielmehr auch darin, diesen Zustand feinster Verteilung möglichst lange aufrechtzuerhalten, d. h. der erzeugten Emulsion eine hohe Stabilität zu verleihen.The purpose of using these substances is not just to help Emulsification process, i.e. bringing about the fine distribution of the substance to be emulsified, but rather also in keeping this state of finest distribution as long as possible to maintain, d. H. to give the emulsion produced a high level of stability.

Besonders von jenen Emulsionen, die technisch in großem Maße Verwendung finden, z. B. Asphaltemulsionen für den Straßenbau, wird einerseits eine leichte Brechbarkeit bei der Verarbeitung, anderseits aber eine Stabilität gefordert, die einen längeren Transport und eine längere Lagerung gestattet.Especially of those emulsions that are used industrially to a large extent find, e.g. B. asphalt emulsions for road construction is on the one hand a light one Breakability during processing, but on the other hand a stability required allows longer transport and storage.

Es ist bereits vorgeschlagen worden, zur Herstellung von Emulsionen auch sauere Farbstoffe anzuwenden, und eine Nachprüfung dieses Verfahrens hat ergeben, daß der Zusatz von geeigneten saueren Farbstoffen der fertigen Emulsion auch einen ziemlich bedeutenden Grad von Stabilität verleiht, der jener der am günstigsten wirkenden bekannten Schutzkolloide gleichkommt.It has already been proposed for the preparation of emulsions also use acidic dyes, and a review of this procedure has shown that the addition of suitable acidic dyes to the finished emulsion also has one gives quite a significant degree of stability, that of the most favorable acting known protective colloids is equivalent.

Immerhin ist die Haltbarkeit solcher mit saueren Farbstoffen hergestellten oder versetzten technischen Emulsionen noch nicht so groß, daß sie einen langen Transport oder eine lange Lagerung unter wechselnden Witterungseinflüssen vertragen, ohne in ihrer Zusammensetzung Schaden zu erleiden.After all, the shelf life is those made with acidic dyes or did not add enough technical emulsions to make them last a long time Can tolerate transport or long storage under changing weather conditions, without suffering damage in their composition.

Eingehende Versuche haben nun gezeigt, daß man diesen technischen Emulsionen eine weit größere Haltbarkeit und Unempfindlichkeit gegen die Einflüsse eines langen Transportes oder einer langen Lagerung geben kann, wenn man ihnen geringe Mengen einer Lösung von saueren Farbstoffen und komplexen Salzen der Cyangruppe zusetzt.In-depth experiments have now shown that this technical Emulsions have a far greater durability and insensitivity to the influences a long transport or a long storage, if you give them low Quantities of a solution of acidic dyes and complex salts of the cyano group clogs.

Nachfolgende Angaben und Beispiele mögen den bedeutenden Fortschritt, der in der Anwendung solcher Mischungen liegt, veranschaulichen.The following information and examples may represent the significant progress which lies in the use of such mixtures.

i. Setzt man einer wässerigen Asphaltemulsion 1,2 Prozent NaCl in Lösung zu, so erfolgt beim Durchmischen eine sofortige Trennung bzw. Ausscheidung des Asphaltes.i. If you put 1.2 percent NaCl in an aqueous asphalt emulsion Solution, an immediate separation or excretion takes place on mixing of the asphalt.

2. Eine mit 0,3 Prozent Natriumoleat stabilisierte Asphaltemulsion trennt sich nach Zusatz von i,2 Prozent NaCl in Lösung in etwa fünf Minuten.2. An asphalt emulsion stabilized with 0.3 percent sodium oleate separates in about five minutes after adding 1.2 percent NaCl in solution.

3. Ein Zusatz von o,2 Prozent Orange R0, in wenig Wasser gelöst, stabilisiert eine Asphaltemulsion so, daß sie auf Zusatz von 1,2 Prozent NaCl in Lösung etwa zwölf Stunden unverändert bleibt, während die salzfreie Emulsion sich monatelang hält.3. An addition of 0.2 percent orange R0, dissolved in a little water, stabilizes an asphalt emulsion so that it is based on the addition of 1.2 percent NaCl in solution remains unchanged for twelve hours, while the salt-free emulsion remains unchanged for months holds.

4. Fügt man jedoch einer Asphaltemulsion 0,i5 Prozent Orange R0 und 0,25 Prozent Ferrocyankalium in wenig Wasser gelöst hinzu, so bleibt sie auch auf Zusatz von 1,2 Prozent NaCl in Lösung tagelang haltbar, geliert dann zunächst, uni schließlich zu brechen. Die salzfreie Emülsion erweist'sch"auch nach sechsmonatlicher Lagerung unter den verschiedensten Witterungseinflüssen höch völlig unverändert.4. However, if 0.15 percent orange R0 and 0.25 percent potassium ferrocyanide dissolved in a little water are added to an asphalt emulsion, it can be kept for days even after adding 1.2 percent NaCl in solution, then initially gels and finally breaks . The salt-free emulsions prove to be completely unchanged even after six months of storage under the most varied of weather conditions.

An Stelle von Orange R0 lassen sich beispielsweise noch verwenden: Orange II (Sulfanilsäure), Metanilgelb, Azokarmin, Echtlichtgrün, Thiokarmin u. dgl.Instead of Orange R0, for example, the following can still be used: Orange II (sulfanilic acid), metanil yellow, azo carmine, real light green, thiocarmine and the like. like

Die Emulsionen selbst erleiden durch diese Zusätze in ihrem Wesen und ihrer Verwendbarkeit keinerlei Veränderung, so daß die Gruppe der saueren Farbstoffe in Verbindung mit den komplexen Salzen der Cyangruppe sich als vorzügliche Stabilisatoren erweisen.The emulsions themselves suffer from these additives in their essence and their usability no change, so that the group of acidic dyes in connection with the complex salts of the cyano group are excellent stabilizers prove.
