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.
