Description

Verfahren zur Herstellung von Netz- und Emulgierungsmitteln Es ist bekannt, daß -trocknende Öle bzw. ihre Säuren mit schwefliger Säure nicht oder nur ganz unvollkommen in Reaktion treten.Process for the production of wetting and emulsifying agents It is known that -drying oils or their acids with sulphurous acid not or only react quite imperfectly.

Es wurde nun die überraschende Beobachtung gemacht, daß Rizinensäure eine Fettsäure mit konjugierten Doppelbindungen, d. h. die Carbonsäure C1sH3,0., welche durch `Vasserabspaltung aus Rizmolsäure gewonnen wird, und ihre Derivate, wie ihr Amid und Glycerid, bei der Behandlung mit Salzen der schwefligen Säure bei Temperaturen von etwa 8o bis ioo° C unter Bildung der entsprechenden wasserlöslichen Sulfonsäuren reagieren.The surprising observation has now been made that ricinic acid a fatty acid with conjugated double bonds, d. H. the carboxylic acid C1sH3,0., which is obtained by splitting off water from rizmolic acid and its derivatives, like their amide and glyceride, when treated with salts of sulphurous acid Temperatures of about 80 to 100 ° C with formation of the corresponding water-soluble Sulphonic acids react.

Die Einwirkungsprodukte werden durch Behandlung mit wäßrigen Lösungen starker Säuren nicht -gespalten. Sie zeichnen sich durch ein hervorragendes Netz- und Emulgierungsvermögen aus. Die neuen Verbindungen sind gegenüber kochenden verdünnten Mineralsäuren beständig, während bei den bekannten Türkischrotölen eine Abspaltung des Schwefelsäurerestes stattfindet. Gegenüber den nach bekannten Verfahren erhältlichen Türkischrotölen zeichnen sich die neuen Produkte durch ein wesentlich höheres Netz- und Emulgierungsvermögen aus. Man braucht im Falle der Ruinensäure nicht von der reinen Säure auszugehen, .sondern man kann dazu das durch Wasserabspaltung aus Rizinusöl erhaltene Produkt direkt oder nach Verseifung verwenden. Das Verfahren selbst kann mit den Salzen der schwefligen Säure in der verschiedensten Weise zur Durchführung gelangen. Auch können evtl. Emulgierungsmittel dem Reaktionsgemisch zur Erleichterung der Anfangsreaktion zugesetzt werden.The products of the action are obtained by treatment with aqueous solutions strong acids are not cleaved. They are characterized by an excellent network and emulsifying power. The new compounds are diluted compared to boiling Mineral acids resistant, while the well-known Turkish red oils split off of the sulfuric acid residue takes place. Compared to those available by known processes Turkish red oils, the new products are characterized by a significantly higher network and emulsifying power. In the case of ruinic acid, there is no need of the pure acid, but you can do this by splitting off water from castor oil Use the product received directly or after saponification. The procedure itself can with the salts of sulphurous acid in the most varied of ways reach. Any emulsifying agents can also be added to the reaction mixture for relief added to the initial reaction.

Beispiel 28o Gewichtsteile Rizinensäure werden mit q.o Gewichtsteilen Ätznatron in heißem Wasser gelöst und mit i 5o Gewichtsteilen Natriumbisulfit ioo%ig (als 38" B6 Sulfitlauge) versetzt und unter sehr gutem mechanischem Durchrühren so lange bei 8o bis, i oo' behandelt, bis eine herausgenommene Probe nach Verdünnen mit Wasser und Ansäuren keine ölige Schicht mehr erkennen läßt. Das Reäktionsprodukt läßt sich mit Kochsalz aus der Reaktionsmasse als helles, klares Öl abscheiden, das sich in Wasser löst und ein ausgezeichnetes Netz- und Emulgierungsvermögen zeigt.Example 28o parts by weight of ricinic acid are mixed with q.o parts by weight Caustic soda dissolved in hot water and ioo% strength with 15o parts by weight of sodium bisulfite (as 38 "B6 sulphite liquor) and with very good mechanical stirring treated at 8o to 'i oo' until a sample has been removed after dilution with water and acidic no more oily layer can be seen. The reaction product can be separated from the reaction mass with common salt as a light, clear oil, which dissolves in water and shows excellent wetting and emulsifying properties.
