Verfahren zur Darstellung von hochviskosen, in Mineralölen löslichen ölen.
Bekanntlich werden fette Öle, Trane, deren Fettsäuren, Ester und ähnliche Derivate durch Oxydation, insbesondere auch durch Einwirkung von Luftsauerstoff, verdickt. Die Verdickung ist im allgemeinen um so grösser, je energischer die Behandlung hinsichtlich Luft-oder Sauerstoffzufuhr, Temperatur, Einwirkungsdauer usw. ist. Es wurde nun gefunden, dass man höchstviskose, in Mineralöl lösliche Öle von besonderer Eignung für verschiedene Zwecke erhält, wenn man Rizinusöl oder Glyzeride und andere Ester der Polyoxydfettsäuren partiell oxydiert und hierauf mehrere Stunden auf über 190 C und nicht über 250 C erhitzt.
Das Erhitzen kenn im Vakuum oder unter gewöhnlichem Druck erfolgen, wobei im letzteren Falle Luftabschluss durch Kohlend : oxyd nicht erforderlich, zumeist nicht einmal vorteilhaft ist.
Zrr Ausführung des Verfahrens verwendet man Rizinusöl oder Polyoxyfettsäureester. Z. B die nach dem österr. Patent Nr. 94942 dargestellten Produkte wie Tririzinolsäureglyzeride, ebenso andere in analoger Weise oder auf anderem Wege dargestelte Glyzeride oder sonstige Ester der Polyrizinolsäuren und analoger Verbindungen.
Die nach dem Verfahren erzeugten Produkte eignen sich vorzüglich zum Einfetten von Leder und für andere gerbereitechnische Zwecke ; sie eignen sich für die Kunstledererzeugung, zum Weichmachen von Textilfasern verschiedenster Art, zum Imprägnieren, für Firnisse, Lacke und Appreturen, zur Bereitung von Emulsionen, Salben u. dgl. Die Lösungen der Produkte, namentlich die Lösungen in Mineralölen, zeichnen sich durch besondere Sehmierfähigkeit aus.
Beispiel : 1200 Tririzinolsäureglyzerid, dargestellt nach Schweizer Patent 94220, werden in
EMI1.1
rund 50 Englergraden bei 1000 C erreicht ist. Hierauf wird die Luftzuführung abgestellt, dann die Temperatur auf 195-2450 C erhöht und für 7-10 Stunden unter schwachem Rühren innerhalb dieser Grenzen gehalten. Das Produkt ist so viskos, dass sich die Zähigkeit im Englerschen Apparate nicht mehr bestimmen lässt.

Process for the preparation of highly viscous oils soluble in mineral oils.
It is known that fatty oils, Trane, their fatty acids, esters and similar derivatives are thickened by oxidation, in particular by the action of atmospheric oxygen. The thickening is generally greater, the more energetic the treatment with regard to air or oxygen supply, temperature, duration of exposure, etc. It has now been found that extremely viscous oils which are particularly suitable for various purposes and which are soluble in mineral oil are obtained if castor oil or glycerides and other esters of polyoxydic fatty acids are partially oxidized and then heated to over 190 C and not over 250 C for several hours.
The heating can be carried out in a vacuum or under normal pressure, in the latter case the exclusion of air by carbon dioxide is not necessary and is usually not even advantageous.
Castor oil or polyoxy fatty acid esters are used to carry out the process. For example, the products presented according to Austrian Patent No. 94942 such as tririzinoleic acid glycerides, as well as other glycerides or other esters of polyrizinoleic acids and analogous compounds presented in an analogous manner or in another way.
The products produced by the process are particularly suitable for greasing leather and for other technical purposes in tanning; they are suitable for the production of artificial leather, for softening textile fibers of various kinds, for impregnation, for varnishes, lacquers and finishes, for the preparation of emulsions, ointments and the like. Like. The solutions of the products, namely the solutions in mineral oils, are distinguished by their particular permeability.
Example: 1200 tririzinoleic acid glyceride, represented according to Swiss patent 94220, are in
EMI1.1
around 50 degrees of Engler at 1000 C is reached. The air supply is then switched off, the temperature is then increased to 195-2450 ° C. and kept within these limits for 7-10 hours with gentle stirring. The product is so viscous that the toughness can no longer be determined in Engler's apparatus.
