Description
Verfahren zur Gewinnung von Sulfonierungsprodukten aus polymerisierten, ungesättigte Oxyfettsäuren enthaltenden Fetten, Ölen oder ihren Säuren Es ist bereits vorgeschlagen worden, Fette oder Fettsäuren bei Gegenwart von wasserfreien organischen Säuren, ihren Anhydriden oder Chloriden zu sulfonieren.Process for the production of sulfonation products from polymerized, Fats, oils or their acids containing unsaturated oxyfatty acids It is already it has been suggested to use fats or fatty acids in the presence of anhydrous organic To sulfonate acids, their anhydrides or chlorides.
Es wurde nun gefunden, daß Produkte mit noch besseren Eigenschaften, insbesondere noch größerer Beständigkeit gegen Salze und Säuren, größerer Viskosität und Schmier-und Erweichungsfähigkeit gewonnen werden, wenn man an Stelle der Fette und Fettsäuren Polymerisationsprodukte von ungesättigte Oxyfettsäuren enthaltenden Ölen bei Gegenwart wasserfreier, niederer aliphatischer Säuren, ihrer Anhydride oder Chloride sulfoniert.It has now been found that products with even better properties, especially greater resistance to salts and acids, greater viscosity and lubricity and softening ability can be gained if one takes in place of the fats and fatty acids containing polymerization products of unsaturated oxy fatty acids Oils in the presence of anhydrous, lower aliphatic acids, their anhydrides or sulfonated chlorides.
Von den ungesättigte Oxvfettsäuren enthaltenden polymerisierbaren Ölen, deren Polymerisationsprodukte in dieser Weise behandelt werden, kommt vorzugsweise das Rizinusöl in Frage. Der Sulfonierung werden unterworfen seine Polymerisationsprodukte, die durch Erhitzen auf hohe Temperatur, wie z. B. 300°, unter Abspaltung von Wasser entstehen (vgl. H e r b i g : »Die Öle und Fette in der Textilindustrie«, Stuttgart 1923, Seite 175 bzw. Seite i i).Of the polymerizable ones containing unsaturated oxyfatty acids Oils whose polymerization products are treated in this way are preferred the castor oil in question. Its polymerization products are subjected to sulfonation, by heating to high temperature, such as. B. 300 °, with elimination of water arise (cf. H e r b i g: "The oils and fats in the textile industry", Stuttgart 1923, page 175 or page i i).
Es ist an sich bekannt, ein derartiges Polymerisationsprodukt des Rizinusöls durch Behandlung mit Schwefelsäure zu sulfonieren. Es ist jedoch noch nicht vorgeschlagen, diese Sulfonierung in der erfindungsgemäßen Art durchzuführen, nämlich in Gegenwart von niedrigmolekularen, wasserfreien, organischen Säuren, ihrer Anhydride oder Chloride. Auch ist über die Eigenschaften der nach dem vorbekannten Verfahren hergestellten Sulfonierungsprodukten des polymerisierten Rizinusöls nichts bekannt geworden.It is known per se, such a polymerization product of the Sulphonate castor oil by treating it with sulfuric acid. However, it still is it is not suggested to carry out this sulfonation in the manner according to the invention, namely in the presence of low molecular weight, anhydrous, organic acids, their Anhydrides or chlorides. Also is known about the properties of the after Process produced sulfonation products of the polymerized castor oil nothing known.
Das Verfahren wird z. B. wie folgt ausgeführt: Beispiel i Man mischt ioo kg polymerisiertes Rizinusöl mit 30 kg Essigsäureanhydrid und behandelt dann das Gemisch in üblicher Weise mit Schwefelsäure. Nach beendigter Reaktion entfernt man vorhandene Essigsäure und überschüssige Schwefelsäure durch Waschen mit kleinen Mengen Wasser.The method is e.g. B. carried out as follows: Example i 100 kg of polymerized castor oil are mixed with 30 kg of acetic anhydride and the mixture is then treated in the usual way with sulfuric acid. After the reaction has ended, any acetic acid and excess sulfuric acid present are removed by washing with small amounts of water.
Beispiel e 3oo kg polymerisierten Rizinusöls werden mit i5o kg Buttersäureanhydrid gemischt und das Gemisch mit 3oo kg Schwefelsäure bei Temperaturen von o bis 5 ° sulfoniert. Nach dem Auswaschen der überschüssigen Schwefelsäure wird das Reaktionsprodukt neutralisiert und stellt ein klar lösliches säure- und alkalibeständiges Öl dar. Beispiel 3 roo kg eines polymerisierten Rizinusöls, das durch Erhitzen von Rizinusöl auf 300° bis zum Austritt von io °f, Wasser entstanden ist, werden mit 5o kg Eisessig gemischt und durch langsame Zugabe von i5o kg konzentrierter Schwefelsäure bei etwa 5° sulfoniert. Nach dem Auswaschen der überschüssigen Schwefelsäür-e# und der Neutralisation des Reaktionsproduktes erhält man ein klar lösliches 'Öl von der gleichen Eigenschaft wie die Öle nach Beispiel z und a.Example e 300 kg of polymerized castor oil are mixed with 150 kg of butyric anhydride mixed and the mixture with 300 kg of sulfuric acid at temperatures of 0 to 5 ° sulfonated. After washing out the excess sulfuric acid, the reaction product becomes neutralized and represents a clearly soluble acid and alkali-resistant oil. Example 3 roo kg of a polymerized castor oil obtained by heating castor oil at 300 ° until io ° f emerges, water is formed with 50 kg of glacial acetic acid mixed and by slowly adding 150 kg of concentrated sulfuric acid at about 5 ° sulfonated. After washing out the excess sulfuric acid-e # and the neutralization of the reaction product gives a clearly soluble oil of the same property as the oils according to example z and a.
