Description
Verführen zur Herstellung eines neuen Sulfierungsproduktes. Es wurde gefunden, dass man ein neues Sulfierungsprodukt erhält, wenn man Rizinusöl in Gegenwart von -Phthalsäureanhydrid-R- sulfosäure mit Sulfierungsmitteln behandelt. Das so dargestellte Sulfierungsprodukt ist ein sehr schwach gelblich braun gefärbtes, in Wasser klar lösliches und stark Schäu mendes Öl, welches sehr beständig ist gegen Härtebildner des Wassers, konzentrierte Alkali- und Bittersalzlösungen.
<I>Beispiel 1:</I> Man löst 41,8 Gewichtsteile Phthalsäure- anhydrid-ss-sulfosäure, welche aus der freien Sulfosäure durch längeres Erhitzen im Vakuum auf 150-1600 hergestellt wurde, in 114 Ge wichtsteilen Monohydrat auf und lässt darauf 57 Gewichtsteile Rizinusöl im Laufe von zirka 2 Stunden hinzutropfen. Durch Kühlen hält man die Temperatur auf etwa 5-100. Das Reaktionsprodukt giesst man darauf auf Eis, zweckmässig unter Zusatz von Kochsalz, und rührt kurze Zeit. Die abgetrennte ölige Schicht. wird nochmals mit Kochsalzlösung gewaschen und das Waschwasser abgezogen.
Nach mehrstündigem Stehen wird das von allfällig noch ausgeschiedener Kochsalzlösung gut trennbare ölige Reaktionsprodukt neu tralisiert und auf den gewünschten Gehalt an Fettsäure gebracht.
<I>Beispiel 2</I> 300 Gewichtsteile Phthalsäureanhydrid werden durch Erhitzen mit 1200 Gewichts- teilen zirka 24% igem Oleum in bekannter Weise in die Phthalsäure-@-sulfosäui-e über geführt.
Zu 123 Gewichtsteilen der so erhal tenen und nicht weiter aufgearbeiteten Sul- fiermasse lässt man 57 Gewichtsteile Rizinusöl unter Rühren im Laufe von 2 Stunden bei zirka 5-100 hinzutropfen. Die Aufarbeitung erfolgt in der gleichen Weise wie im vorigen Beispiel.
Seduce to manufacture a new sulfonation product It has been found that a new sulfonation product is obtained if castor oil is treated with sulfonating agents in the presence of -phthalic anhydride-R- sulfonic acid. The sulphonation product shown in this way is a very pale yellowish brown colored, clearly soluble in water and strongly foaming oil, which is very resistant to hardness components of water, concentrated alkali and Epsom salt solutions.
<I> Example 1: </I> 41.8 parts by weight of phthalic anhydride-β-sulfonic acid, which was prepared from the free sulfonic acid by prolonged heating in vacuo to 150-1600, are dissolved in 114 parts by weight of monohydrate and left thereon Add 57 parts by weight of castor oil over the course of about 2 hours. The temperature is kept at about 5-100 by cooling. The reaction product is then poured onto ice, advantageously with the addition of sodium chloride, and stirred for a short time. The separated oily layer. is washed again with saline solution and the washing water is drawn off.
After standing for several hours, the oily reaction product, which can be easily separated from any saline solution that may still be excreted, is neutralized and brought to the desired fatty acid content.
<I> Example 2 </I> 300 parts by weight of phthalic anhydride are converted into the phthalic acid - @ - sulfonic acid in a known manner by heating with 1200 parts by weight of about 24% strength oleum.
57 parts by weight of castor oil are added dropwise to 123 parts by weight of the sulphurous mass obtained in this way and not worked up further, with stirring over the course of 2 hours at about 5-100. The work-up is carried out in the same way as in the previous example.
