Verfahren zur Gewinnung von Fettsäuren.
Die meisten Verfahren der Gewinnung fester Fettsäuren aus ungesättigten Fettsäuren oder deren Glyzeriden beruhen bekanntlich auf der Einwirkung konzentrierter Schwefelsäure auf dieselben bei Temperaturen von 60 bis 1200 C, Entfernen der überschüssigen Schwefelsäure durch Auswaschen mit Wasser oder einer Salzlösung und Destillieren des so erhaltenen Produktes. Es ist bekannt, dass auch Ölsäure bei einer derartigen Behand) ung eine Sulfosäure liefert. Bei den bekannten Verfahren nun bilden sich immer grosse Quantitäten von Kohlenwasserstoffen, wobei das Destillat dunkel gefärbt ist ; die Ursache suchte man allgemein in der Zersetzung der vorhandenen Oxystearinsäure.
Nach Anschauung des Erfinders bilden sich bei der Einwirkung von konzentrierter Schwefelsäure in der Hitze auf ungesättigte Fettsäuren und darauffolgendem Destillieren
EMI1.1
bleibt aber immer, auch bei stundenlangem Aufkochen mit Wasser, etwas Schwefelsäure in gebundener Form in dem Rcaktionsgemischp zurück, welche beim darauffolgenden Destillieren zerstörend auf die Fettsäuren unter Bildung von Kohlenwasserstoffen und Teer einwirkt. Wird dem Fettsäuregcmische aber vor der Destination ein Oxyd, Karbonat oder ein anderer die Säure bindender Körper in vorher berechneter Menge hinzugezetzt, derart, dass die Schwefelsäure fast vollständig gebunden wird, so geht die Destillation glatt und bei geringer Bildung von Kohlenwasserstoffen von statten.
Beispiel :

EMI1.2
Dieselben Fettsäuren mit 3,5% Natriumkarbonat oder 3% Ätzkalk versetzt, ergeben bei Destillation unter denselben Bedingungen ein viel hellenes, fast geruchloses Destillat, welches 1,2% ungerseifbare Substanz enthält, stärker abdestilliert werden kann als im vorhergehenden Falle und dessen zuletzt übergehenden Anteile trotzdem nur 4. 80/0 unter- seifban'n Anteil enthalten.
Dem Teer wurde durch Auskochen mit Wasser eine bedeutende Quantität Natriumsulfat entzogen, somit hat sich die in dem Fottsäuregemische vorhandene gebundene Schwefelsäure mit dem Natriumkarbonat zu Sulfat umgesetzt und dadurch die zerstörende Wirkung der beim Destillieren freiwerdenden und sich konzentrierenden Schwefesäure neutralisiert.

Process for the production of fatty acids.
Most of the methods of obtaining solid fatty acids from unsaturated fatty acids or their glycerides are known to be based on the action of concentrated sulfuric acid on the same at temperatures of 60 to 1200 C, removing the excess sulfuric acid by washing it out with water or a salt solution and distilling the product thus obtained. It is known that oleic acid also gives a sulfonic acid in such a treatment. In the known processes, large quantities of hydrocarbons are always formed, the distillate being dark in color; the cause was generally sought in the decomposition of the oxystearic acid present.
According to the inventor, when concentrated sulfuric acid is exposed to heat, unsaturated fatty acids are formed and then distilled
EMI1.1
But there is always, even after boiling with water for hours, some sulfuric acid in bound form in the reaction mixture, which in the subsequent distillation has a destructive effect on the fatty acids with the formation of hydrocarbons and tar. If, however, an oxide, carbonate or some other acid-binding body is added to the fatty acid mixture in a previously calculated amount, in such a way that the sulfuric acid is almost completely bound, then the distillation proceeds smoothly and with little formation of hydrocarbons.
Example:
A load with 35% concentrated sulfuric acid for 10 hours at 60 to 700 C
EMI1.2
The same fatty acids mixed with 3.5% sodium carbonate or 3% quick lime result in distillation under the same conditions a much pale, almost odorless distillate, which contains 1.2% unsaponifiable substance, can be distilled off more strongly than in the previous case and its last part nevertheless only contain 4. 80/0 sub-soapy portion.
A significant amount of sodium sulphate was removed from the tar by boiling it with water, so the bound sulfuric acid present in the acid mixture has reacted with the sodium carbonate to form sulphate, thereby neutralizing the destructive effect of the concentrated sulfuric acid released during distillation.
