Description
Verfahren zur Darstellung höher molekularer Sulfosäuren. Bei der Sulfurierung organischer Ver bindungen, insbesondere des Rizinusöls, wird im allgemeinen Schwefelsäure verwandt, die möglichst hochprozentig eine mehr oder min der weitgehende Substitution des der Sul- furierung unterworfenen Körpers durch die Sulfogruppe herbeizuführen vermag.
Höher molekulare aliphatische, namentlich gesättigte Alkohole liessen sich aber auf diese Weise nicht in die entsprechenden Sulfosäuren über führen, die, wie zum Beispiel die Cetylsulfo- säure, bisher nur in ausserordentlich umständ licher Weise zugänglich sind.
Wenn man nun dieses Verfahren in der besonderen Arbeitsweise ausführt, dass man die Sulfurierung der höher molekularen ali- phatischen Alkohole in Gegenwart wasser bindender Substanzen ausführt, so gelangt man zu vollkommen brauchbaren Ergebnis sen. Zweckmässig wird dabei unter Zusatz von Verdünnungsmitteln gearbeitet, wie auch unter Zusatz von Katalysatoren.
Als letz- tere sind zum Beispiel Phosphorsäureanhy- drid, aktive Kohle oder dergleichen geeignet und als Verdünnungsmittel zum Beispiel Nitrobenzol oder Tetrachlorkohlenstoff. Die wasserbindenden Substanzen können anorga nische Säureanhydride, zum Beispiel Sehwe- felsäureanhydrid, oder organische Säurean- hydride, zum Beispiel Essigsäureanhydrid oder Phtalsäureanhydrid, sein.
Neben hoch konzentrierter Schwefelsäure können als Sul- furierungsmittel auch noch Säurehalogenide Verwendung finden.
Beispielsweise vermischt man 1 Mol. Ce- tylalkohol mit li/#" Mol. 98%iger Schwefel säure, erwärmt das Ganze allmählich auf 100 C und rührt gleichzeitig etwas über 1 Mol. Essigsäureanhydrid hinein. Nach mehrstündigem Rühren giesst man in Eis wasser und wäscht, gegebenenfalls nach Zu satz von Glaubersalz, aus. Die Alkalisalze der Cetylsulfosäure können direkt oder über das Calciumsalz erhalten werden.
An Stelle des in obigem Beispiel ver wandten Cetylalkohols können mit gleichem Erfolge auch noch andere, höher molekulare Alkohole, zum Beispiel die Alkohole des Wollfettes, des Bienenwachses und derglei chen, aber auch stärker ungesättigte Pro dukte, wie zum Beispiel die aus dem Spermöl isolierbaren Alkohole, verwendet werden.
Die erhaltenen Produkte sollen vor nehmlich als Netz-, Emulgierungs- und Rei nigungsmittel Verwendung finden.
Process for the preparation of high molecular weight sulfonic acids. In the sulphuration of organic compounds, in particular of castor oil, sulfuric acid is generally used, which is able to bring about a more or more extensive substitution of the body subjected to sulphuration by the sulpho group as high as possible.
However, higher molecular weight aliphatic, namely saturated alcohols could not be converted in this way into the corresponding sulfonic acids, which, like for example cetyl sulfonic acid, have hitherto only been accessible in an extremely laborious manner.
If you now carry out this process in the special procedure that the sulfurization of the higher molecular weight aliphatic alcohols is carried out in the presence of water-binding substances, one arrives at completely usable results sen. It is expedient to work with the addition of diluents, as well as with the addition of catalysts.
Phosphoric anhydride, active charcoal or the like, for example, are suitable as the latter, and nitrobenzene or carbon tetrachloride, for example, as diluents. The water-binding substances can be inorganic acid anhydrides, for example sulfuric acid anhydride, or organic acid anhydrides, for example acetic acid anhydride or phthalic acid anhydride.
In addition to highly concentrated sulfuric acid, acid halides can also be used as sulphurating agents.
For example, 1 mol of cetyl alcohol is mixed with 1 mol. 98% strength sulfuric acid, the whole is gradually heated to 100 ° C. and at the same time a little over 1 mol of acetic anhydride is stirred in. After several hours of stirring, water is poured into ice and washed , optionally after the addition of Glauber's salt, from The alkali metal salts of cetylsulfonic acid can be obtained directly or via the calcium salt.
Instead of the cetyl alcohol used in the above example, other, higher molecular alcohols, for example the alcohols from wool fat, beeswax and the like, but also more unsaturated products, such as the alcohols that can be isolated from sperm oil, can be used with the same success , be used.
The products obtained should primarily be used as wetting, emulsifying and cleaning agents.
