Description

Verfahren zur Gewinnung von Sulfosäuren. Es wurde die Beobachtung gemacht, daß man Sulfosäuren aus neutralen Urteerleichtölen erhält, wenn man dieselben untergelinden Bedingungen mit sulfurierenden Mitteln behandelt, insbesondere mit konzentrierter Schwefelsäure, Schwefelsäuremonohydrat, rauchender Schwefelsäure oder Chlorsulfonsäure. Die so erhaltenen Sulfosäuren sollen Verwendung z. B. als Desinfektionsmittel, als schaumbildende Mittel und als Holzim_prägnierungsmittel finden. Sie bilden auch zum Teil Zwischenpro'd'ukte zur Herstellung solcher Stoffe.Process for the production of sulphonic acids. It became observation made that sulphonic acids are obtained from neutral primal light oils if they are used treated under mild conditions with sulphurizing agents, especially with concentrated sulfuric acid, sulfuric acid monohydrate, fuming sulfuric acid or chlorosulfonic acid. The sulfonic acids obtained in this way are intended to be used, for. B. as Disinfectants, as foaming agents and as wood impregnation agents Find. Some of them also form intermediate products for the manufacture of such substances.

Beispiel I.Example I.

In ioo Teile Urteerneutralöl vom Siedepunkt i i i ° läBt man unter guter Kühlung und Rühren i oo Teile Schwefelsäuremonohydrat einfließen, rührt noch % Stunde nach, trennt die dicke, bräunlich gefärbte Säureschicht von dem unangegriffenen Kohlenwasserstoff ab und versetzt die Säure mit 2o Teilen Eis unter guter Kühlung. Nach kurzer Zeit erstarrt die Säureschicht zu einem Kristallbrei von feinen farblosen Nadeln, welche abgesaugt und mit Schwefelsäure von 6o° B6 ausgewaschen werden. Die Sulfosäure ist in Wasser und konzentrierter Schwefelsäure sehr leicht löslich. Sie bildet mit den Alkalien und Erdalkalien leichtlösliche Salze. Das Ammoniumsalz kristalH-siert in großen quadratischen Tafeln, das Bariumsalz in perlmutterglänzenden Blättchen. Die Ausbeute beträgt etwa 65 Prozent der angewandten Menge.100 parts of natural tar neutral oil with a boiling point of i i ° are omitted Good cooling and stirring, pour in 100 parts of sulfuric acid monohydrate, stir % Hour after, the thick, brownish colored acid layer separates from the unaffected Hydrocarbon and treated the acid with 20 parts of ice with good cooling. After a short time, the acid layer solidifies to form a fine, colorless crystal pulp Needles which are sucked off and washed out with sulfuric acid at 60 ° B6. the Sulphonic acid is very easily soluble in water and concentrated sulfuric acid. she forms easily soluble salts with the alkalis and alkaline earths. The ammonium salt crystallizes in large square tablets, the barium salt in pearlescent leaves. The yield is about 65 percent of the amount used.

Beispiel Il.Example Il.

Ersetzt man den Kohlenwasserstoff vom Siedepunkt i r i ° in Beispiel I durch den Kohlenwasserstoff vom Siedepunkt 8o°, so erhält man nach dem Abkalken der Schwefelsäure das Calciumsalz einer anderen Säure, welches durch Behandlung mit Soda in ein gut kristallisierendes, leichtlösliches Natriumsalz verwandelt werden kann.If one replaces the hydrocarbon with boiling point i r i ° in example I by the hydrocarbon with a boiling point of 80 ° is obtained after liming of sulfuric acid, the calcium salt of another acid, which by treatment can be converted into a readily crystallizing, easily soluble sodium salt with soda can.
