Description
Verfahren zur Herstellung eines Disulfonsäurechlorids. Es wurde gefunden, dass man das 1- Carbonsäure-'3' . 5,benzoldisulfonsäurechlorid <B>ei.</B> M. 14,690 (1893) erhält, wenn man Ben- zoesäure mit Chlorsulfonsäure unter Zusatz von Oleum erhitzt.
<I>Beispiel:</I> 240 Teeile Benzoesäure werden in 1100 Teile Chlorsulfonsäure kalt eingetragen. worauf 9.00 Teile 66%iges <B>,</B>Oleum zugesetzt werden. Das Gemisch wird hierauf im Auto klaven während dTei :Stunden auf Tempe raturen zwischen<B>M'</B> und 200' erhitzt.
Nachdem das Reaktionsgemisch erkaltet ist, wird unter Rühren, auf Eis fliessen gelassen, das ausgefallene Disulfochlorid abgenutscht und gut mit Wasser ausgewaschen.
Das so erhaltene Produkt ist fast weiss. Durch Um- kristallisieren aus Benzol, oder vorteilhafter aus Chlorbenzol, wird (das reine<B>3.</B> .5-I?i8ulfo- chlorid vom F'.193 erhalten.
Process for the preparation of a disulfonic acid chloride. It was found that one can get the 1-carboxylic acid-'3 '. 5, benzene disulphonic acid chloride <B> ei. </B> M. 14,690 (1893) is obtained when benzoic acid is heated with chlorosulphonic acid with the addition of oleum.
<I> Example: </I> 240 parts of benzoic acid are added cold to 1100 parts of chlorosulphonic acid. whereupon 9.00 parts of 66% oleum are added. The mixture is then heated to temperatures between <B> M '</B> and 200' in the autoclave for dTei: hours.
After the reaction mixture has cooled, it is allowed to flow on ice with stirring, the precipitated disulfochloride is suction filtered and washed thoroughly with water.
The product thus obtained is almost white. By recrystallization from benzene, or more advantageously from chlorobenzene, (the pure <B> 3. </B> .5-I8ulfochlorid from F'.193 is obtained.
