Benzin wird aus dem Grunde vorzugsweise als Lösungsmittel gewählt, weil ein kleiner Prozentsatz unzerlegter Kalkseife sich in diesem Kohlenwasserstoffe gleichfalls löst. Schliesslich ist noch zu bemerken, dass das Kalziumsulfit mit zwei Molekülen Krystallwasser krystallisiert, welche gleichfalls dem Gemisch entzogen werden, so dass sich nach beendigter Reaktion ein Produkt von verhältnismässig geringem Wassergehalt ergibt.

und Luft von Schwefligsäureanhydrid mitreissen lässt ; hiebei wird Kalziumsulfat an Stelle von Kalziumsulfit als Nebenprodukt erhalten. Es bedarf nicht der Ausführung, dass die bekannte Verwendung von Schwefligsäure als Bleichmittel für Fette und Öle mit dem vorliegenden Verfahren in keinem Zusammenhange steht.
PATENT-ANSPRÜC'HR :
1. Verfahren zur Gewinnung von Fettsäuren aus der bei der Verseifung von Fetten mit Atzkalk resultierenden Kalkseife, dadurch gekennzeichnet, dass man die Seife der Einwirkung eines heissen Stromes von Schwefligsäureanhydrid aussetzt.

Gasoline is the preferred solvent for the reason that a small percentage of undecomposed lime soap will also dissolve in this hydrocarbon. Finally, it should also be noted that the calcium sulfite crystallizes with two molecules of crystalline water, which are also removed from the mixture, so that after the reaction has ended, a product with a relatively low water content results.
EMI2.1
and air is entrained by sulfurous anhydride; calcium sulfate is obtained as a by-product instead of calcium sulfite. It does not need to be stated that the known use of sulfurous acid as a bleaching agent for fats and oils is not related to the present process.
PATENT CLAIM:
1. A process for obtaining fatty acids from the lime soap resulting from the saponification of fats with quicklime, characterized in that the soap is exposed to the action of a hot stream of sulfurous anhydride.
