Description
Verfahren zur Herstellung eines Mittels zur Erhöhung der I%apillaraktivität 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 den durch Reduktion der Kokosfettsäuren erhältlichen technischen Kokosfettalkohol, eine einen Alkohol in einen Schwefelsäureester überführende Sub stanz und technische Pyridinbasen 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, z. B. Chlor- sulfonsäure, behandelt und das so erhaltene Produkt auf den Alkohol einwirken lässt.
<I>Beispiel:</I> In 75 Teile technische Pyridinbasen (mittleres Molekulargewicht =100) werden unter Rühren und Kühlen 37 Teile Chlor- sulfonsäure eingetragen, wobei die Temperatur nicht über 45 steigen soll. Dann werden 75 Teile technischer Kokosfettalkohol in kleinen Mengen unter weiterem Rühren ein getragen, wobei die Temperatur auf etwa 45-50 gehalten wird. Nach dem Eintragen des Alkohols ist die klasse meist schon wasserlöslich, andernfalls wird noch so lange weitergerührt, bis sich eine Probe in Wasser klar löst. Das Produkt wird dann im ge schlossenen Reaktionsgefäss 14 Stunden auf <B>150-1550</B> erhitzt.
Das neue Produkt ist nach dem Erkalten eine braune Masse, die in Wasser leicht zu einer stark schäumenden Flüssigkeit mit hoher Netzwirkung löslich ist. Die wässerige Lösung hat die Eigenschaft, die Bildung positiv geladener Dispersionen zu befördern, dagegen negativ geladene Dis persionen auszufällen. Das Produkt ist gegen konzentrierte Mineralsäure durchaus bestän dig.
Process for the preparation of an agent for increasing the 1% apillary 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 the technical coconut fatty alcohol obtainable by reducing the coconut fatty acids, a substance converting an alcohol into a sulfuric acid ester, and technical pyridine bases in approximately molecular quantities are allowed to act on one another at elevated temperature and pressure.
The most advantageous embodiment of the process is carried out in such a way that first the technical pyridine bases with the substance converting an alcohol into a sulfuric acid ester, e.g. B. chlorosulfonic acid, treated and the product thus obtained can act on the alcohol.
<I> Example: </I> 37 parts of chlorosulfonic acid are introduced into 75 parts of technical pyridine bases (average molecular weight = 100) with stirring and cooling, the temperature not exceeding 45%. Then 75 parts of technical coconut fatty alcohol are introduced in small amounts with continued stirring, the temperature being kept at about 45-50. After entering the alcohol, the class is usually already water-soluble, otherwise stirring is continued until a sample dissolves clearly in water. The product is then heated to <B> 150-1550 </B> in the closed reaction vessel for 14 hours.
After cooling, the new product is a brown mass that 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, but precipitating negatively charged dispersions. The product is quite resistant to concentrated mineral acids.
