Description
Verfahren zur Herstellung von Emulgier-, Netz- und Waschmitteln. Es ist bekannt, dass Aluminiumhydroxyd in hydratisierter (Gel-) Form emulgierende Eigenschaften besitzt. So wird z. B. gel- artiges Aluminiumhydroxyd zum Stabilisieren fertiger Emulsionen sowie als Dispergier- mit.tel für pulverförmige Stoffe verwendet.
Eingehende Untersuchungen von K. Linder ( Die kolloidehemischen und waschtechni schen hinenschaften hydratisierbarer Kolloide itn Vergleich mit der Seife , Fette und Sei fen, Bd.43 [1936], 5.214- 218und253-256) ergaben jedoch für Aluminiumozydhydrat nur schwache emulgierende Wirkung, welche sieh zu derjenigen des Natriumoleats etwa wie 1 :500 verhält. Ein nennenswertes Wasch vermögen kommt der Verbindung nicht zu.
Eine Erhöhung der emulgierenden Eigen schaften des Aluminiumhydroxyc1-Gels wurde bereits auf verschiedene Art versucht. So bei spielsweise durch Aktivierung mit ultravio lettem Lieht oder durch Reifung vermittels Aufschlämmen in kochendem alkalihaltigem Wasser.
Einer praktischen Verwendung der ober flächenaktiven Eigenschaften des Aluminium hydroxyds standen bisher zudem noch fol gende Nachteile im Wege: 1. Um die strukturelle Eigenart des frisch gefällten Gels zu erhalten, mussten derartige Produkte einen hohen Wassergehalt (etwa 90%) aufweisen. Dementsprechend war die Konzentration an wirksamer Substanz sehr gering. 2. Mit hydratisiertem Aluminiumhydroxyd hergestellte halbfeste Emulsionen (Salben usw.) werden bald an der Oberfläche hart, weil sich infolge der Wasserverdunstung das Gel. in festes Hydroxyd umwandelt.
3. Das Gel selbst scheidet beim Aufbewah ren Quetschwasser aus oder trocknet völlig ein und kann durch erneute Wasserzugabe nicht mehr regeneriert werden.
Gegenstand vorliegender Erfindung ist ein Verfahren zur Herstellung von Emulgier-, Netz- und Waschmitteln, welche ein Alumi- niumhy droxyd-Gel enthalten, wobei das Was ser weitgehend durch Oxy alky lamine ersetzt wird, welche letzteren infolge ihrer Basizitä.t gleichzeitig zur Fällung des Hydroxyds aus hochkonzentrierten Aluminiumsalzlösungen dienen.
Das gefällte Gel bildet mit dem Oxy- alkylamin ein stabiles Adsorbat, welches vor Veränderungen durch Wasserabscheidung und Austrocknen geschützt ist. Zudem wird die Oberflächenwirkung des Systems durch die Oxy alky lamine, welche bekanntlich schon an sieh kapillaraktiv sind, bedeutend erhöht.
Durch Wahl verschiedener Oxyalkylamine, durch Zugabe fester oder flüssiger Fettstoffe zu den Aminen vor der Fällung mit gleich zeitiger Verseifung, durch Nachbehandeln des Produktes mittels Pressen oder Walzen, wer den rmulgier-, Netz- und Waschmittel für die verschiedensten Verwendungsmöglieh- keiten erhalten.
Die Vorteile der nach diesem neuen Ver fahren hergestellten Produkte gegenüber reinem Aluminiiilnhydroxyd-(l el sind dem nach: Hoher Anteil an oberflächenaktiver Substanz, Stabilität und Vermeidung des Aus trocknens, gesteigerte Wirksamkeit, vielseitige Variations- und Verwendungsmöglichkeit. <I>Beispiele:</I> 1. 100 g Aluminiumsulfat werden mit 75 g Wasser erhitzt, bis eine völlige Lösung einge treten ist. In die noch warme Lösung werden 110 g Triäthanolamin langsam eingerührt und bis zum Erkalten gut durchgemischt.
End produkt: 250 g pastenartige, schwach gelb liche Masse; Wassergehalt 16%. Emulgier- mittel.
2. 100g Aluminiumsulfat werden in 75 g Wasser unter Erhitzen völlig gelöst, darauf der heissen Lösung 81 g auf etwa 80 erwärm tes Diäthanolamin unter Rühren zugesetzt, wobei die Neutralisationsw ärme eine weitere Erhitzung der Masse und Verdampfung des überschüssigen Wassers bedingt. Nach Erkal ten wird das Produkt durch ein Salbenwalz werk getrieben. Endprodukt: etwa 200 g sal benartige, farblose, nahezu transparente Masse; Wassergehalt etwa 10%. Emulgier- und Netzmittel.
3. 115 g Triäthanolamin werden in der Wärme mit 12 g Olein versetzt und in diese Mischung eine warme Lösung von 100g Alu miniumsulfat in 70 g Wasser eingerührt. End produkt: 260 g gelbliche Paste. Waschmittel mit sehr guter Emulgierfähigkeit.
Die nach dem beschriebenen Verfahren hergestellten Produkte können in der Textil- und Lederindustrie, für pharmazeutische und kosmetische Zwecke, in Schmierstoffen, Schäd- lingsbekämpfungs-, Desinfektions-, Reini gungsmitteln usw. Verwendung finden.
Process for the production of emulsifiers, wetting agents and detergents. It is known that aluminum hydroxide in hydrated (gel) form has emulsifying properties. So z. B. gel-like aluminum hydroxide used to stabilize finished emulsions and as a dispersing agent for powdery substances.
In-depth investigations by K. Linder (the chemical properties of hydratable colloids in comparison with the soap, fats and soap, Vol. 43 [1936], 5.214-218 and 253-256) showed only a weak emulsifying effect for aluminum hydrate, which you can see to that of sodium oleate about 1: 500. The compound does not have any noteworthy washing power.
Attempts have already been made in various ways to increase the emulsifying properties of the aluminum hydroxyc1 gel. For example, through activation with ultraviolet light or through maturation by means of slurrying in boiling alkaline water.
The practical use of the surface-active properties of the aluminum hydroxide has hitherto also stood in the way of the following disadvantages: 1. In order to maintain the structural characteristics of the freshly precipitated gel, such products had to have a high water content (about 90%). Accordingly, the concentration of the active substance was very low. 2. Semi-solid emulsions (ointments, etc.) made with hydrated aluminum hydroxide soon harden on the surface because the water evaporates into the gel. converts to solid hydroxide.
3. The gel itself separates from squeeze water when it is stored or dries up completely and cannot be regenerated by adding more water.
The present invention relates to a process for the production of emulsifiers, wetting agents and detergents which contain an aluminum hydroxide gel, the water being largely replaced by oxyalkylamines, which, due to their basicity, simultaneously precipitate the Serve hydroxyds from highly concentrated aluminum salt solutions.
The precipitated gel forms a stable adsorbate with the oxyalkylamine, which is protected from changes due to water separation and drying out. In addition, the surface effect of the system is significantly increased by the oxyalky lamines, which are known to be capillary active.
By choosing different oxyalkylamines, by adding solid or liquid fatty substances to the amines before precipitation with simultaneous saponification, by post-treating the product by pressing or rolling, you get the emulsifying, wetting and washing agents for a wide variety of uses.
The advantages of the products manufactured according to this new process compared to pure aluminum hydroxide (l el are accordingly: high proportion of surface-active substance, stability and avoidance of drying out, increased effectiveness, versatile variation and possible uses. <I> Examples: </ I> 1. 100 g of aluminum sulfate are heated with 75 g of water until a complete solution has come in. 110 g of triethanolamine are slowly stirred into the still warm solution and mixed well until it cools.
End product: 250 g pasty, slightly yellowish mass; Water content 16%. Emulsifier.
2. 100 g of aluminum sulfate are completely dissolved in 75 g of water with heating, then 81 g of diethanolamine are added to the hot solution while stirring, the heat of neutralization causing further heating of the mass and evaporation of the excess water. After cooling, the product is driven through an ointment roller. End product: about 200 g ointment-like, colorless, almost transparent mass; Water content about 10%. Emulsifying and wetting agents.
3. 115 g of triethanolamine are mixed with 12 g of olein while hot and a warm solution of 100 g of aluminum sulfate in 70 g of water is stirred into this mixture. End product: 260 g yellowish paste. Detergent with very good emulsifying properties.
The products produced by the process described can be used in the textile and leather industry, for pharmaceutical and cosmetic purposes, in lubricants, pest control agents, disinfectants, cleaning agents, and the like.
