Description
Verfahren zur Herstellung eines Mittels zur Erhöhung der liapillaraktivität von Flüssigkeiten. Gegenstand vorliegenden Patentes ist ein Verfahren zur Herstellung eines Mittels zur Erhöhung der Kapillaraktivität von Flüssig keiten. Das Verfahren ist dadurch gekenn zeichnet, dass man Cetylalkohol, eine einen Alkohol in einen Schwefelsäureester über führende Substanz und Pyridin in etwa molekularen Mengen bei erhöhter Temperatur und Druck aufeinander einwirken lässt.
Die vorteilhafteste Ausführungsform des Verfahrens wird derart durchgeführt, dass man zuerst das Pyridin mit der einen Alkohol in einen Schwefelsäureester überführenden Sub stanz, z. B. Chlorsulfonsäure, behandelt und das so erhaltene Produkt auf den Alkohol einwirken lässt.
<I>Beispiel:</I> In 40 Teile Pyridin werden 30 Teile Chlor- sulfonsäure bei 30 unter Rühren und Kühlen eingetragen, dann bei 45' eine Lösung von 50 Teilen Cetylalkohol in 40 Teilen warmem Pyridin eingerührt und so lange auf 501 er wärmt, bis eine Probe in warmem Wasser klar löslich ist. Das Reaktionsprodukt wird im geschlossenen Reaktionsgefäss. 18 Stunden auf 160-180 erhitzt. Das Reaktionsprodukt ist nach dem Erkalten eine ziemlich feste, braune Masse. Sie ist löslich in Wasser zu einer stark schäumenden Lösung.
Durch Auf nehmen in Alkohol, Schütteln mit Tierkohle, Abfiltrieren der Tierkohle und Ausfällen der alkoholischen Lösung mittelst Äther kann eine Reinigung erzielt werden. Man erhält dann die neue Verbindung. als weisse, ziemlich feste Masse, die in Wasser leicht zu einer stark schäumenden Flüssigkeit mit hoher Netzwirkung löslich ist. Die wässerige Lösung hat die Eigenschaft, die Bildung positiv ge ladener Dispersionen zu befördern, dagegen negativ geladene Dispersionen auszufällen. Das Produkt ist gegen konzentrierte Mineralsäure durchaus beständig.
Process for the preparation of an agent for increasing the liapillary activity of liquids. The present patent is a process for the preparation of an agent for increasing the capillary activity of liquids. The method is characterized in that cetyl alcohol, a substance which converts an alcohol into a sulfuric acid ester, and pyridine in approximately molecular amounts are allowed to act on one another at elevated temperature and pressure.
The most advantageous embodiment of the method is carried out in such a way that first the pyridine with the substance converting an alcohol into a sulfuric acid ester, eg. B. chlorosulfonic acid treated and the product thus obtained can act on the alcohol.
<I> Example: </I> 30 parts of chlorosulfonic acid are introduced into 40 parts of pyridine at 30 ° with stirring and cooling, then a solution of 50 parts of cetyl alcohol in 40 parts of warm pyridine is stirred in at 45 'and warmed to 501 for so long until a sample is clearly soluble in warm water. The reaction product is in the closed reaction vessel. Heated to 160-180 for 18 hours. After cooling, the reaction product is a fairly solid, brown mass. It is soluble in water to form a strong foaming solution.
Purification can be achieved by taking up in alcohol, shaking with animal charcoal, filtering off the animal charcoal and precipitating the alcoholic solution using ether. You then get the new connection. as a white, fairly solid mass which is easily soluble in water to form a strongly foaming liquid with a high wetting effect. The aqueous solution has the property of promoting the formation of positively charged dispersions, while on the other hand precipitating negatively charged dispersions. The product is quite resistant to concentrated mineral acids.
