Description

  

  Verfahren zur     Tierstellung    eines Mittels zur Erhöhung der     Irapillaraktivität    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     Octadecen-12-ol-1,    eine  einen Alkohol in einen     Schwefelsäureester     überführende Substanz und technische     Py-          ridinbasen    in etwa molekularen Mengen bei  erhöhter Temperatur und Druck aufeinander  einwirken lässt.  



  Die vorteilhafteste Ausführungsform des  Verfahrens wird derart durchgeführt, dass  man zuerst die technischen     Pyridinbasen    mit  der einen Alkohol in einen     Schwefelsäure-          ester    überführenden Substanz, zum Beispiel       Chlorsulfonsäure,    behandelt und das so er  haltene Produkt auf den Alkohol einwirken  lässt.  



       Beispiel:     In 80 Teile technische     Pyridinbasen    trägt  man 24 Teile     Chlorsulfonsäure    unter Rühren  und Kühlen ein, so dass die Temperatur 20<B>0</B>    nicht übersteigt. Dann werden 55 Teile       Octadecen-12-ol-1    bei 450 zugegeben, und  es wird so lange auf dieser Temperatur ge  halten, bis eine herausgenommene Probe  sich als wasserlöslich erweist. Das Produkt  wird dann im geschlossenen Reaktionsgefäss  8 Stunden auf 170 bis 180   erhitzt. Nach  dem Erkalten ist das neue Reaktionsprodukt  eine braune, salbenartige Masse, die in  Wasser leicht zu einer stark schäumenden  Flüssigkeit mit hoher Netzwirkung löslich  ist.

   Die wässerige Lösung hat die Eigen  schaft, die Bildung positiv geladener Disper  sionen zu befördern, dagegen negativ ge  ladene Dispersionen auszufällen. Das Pro  dukt ist gegen konzentrierte Mineralsäure  durchaus beständig.



  Method for producing an agent for increasing the irapillary activity of liquids. The present patent is a process for the preparation of an agent for increasing the capillary activity of liquids. The process is characterized in that octadecen-12-ol-1, a substance converting an alcohol into a sulfuric acid ester, and technical pyridine bases are allowed to act on one another in approximately molecular amounts at elevated temperature and pressure.



  The most advantageous embodiment of the process is carried out in such a way that the technical pyridine bases are first treated with the substance which converts an alcohol into a sulfuric acid ester, for example chlorosulfonic acid, and the product thus obtained is allowed to act on the alcohol.



       Example: 24 parts of chlorosulfonic acid are introduced into 80 parts of technical pyridine bases with stirring and cooling, so that the temperature does not exceed 20. Then 55 parts of octadecen-12-ol-1 are added at 450, and it is kept at this temperature until a sample removed proves to be water-soluble. The product is then heated to 170 to 180 hours in the closed reaction vessel. After cooling, the new reaction product is a brown, ointment-like mass that is easily soluble in water to form a strongly foaming liquid with a high wetting effect.

   The watery 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.
