Description
Verfahren zur Herstellung eines Sulfons. Es wurde gefunden, dass man ein neues Sulfon erhält, wenn man ein Salz der p-To- luolsulfirrsäure mit einem a-Halogenlaurin- säureäthylester umsetzt.
Das neue Sulfon bildet ein gelbliches Öl, das als Zwischenprodukt Verwendung finden soll.
<I>Beispiel:</I> 25 Gewichtsteilea-Bromlaurinsäureäthylester werden mit einer solchen Menge toluolsulfin- saurem Natrium, als 17,4 Gewichtsteilen reinem Sulfinat entspricht, und 90 Raum teilen Äthylalkohol während etwa 11 Stun den in einem Rührautoklaven auf 150-160 gehalten. Man verdünnt darauf das Reaktions- produkt mit Wasser und schüttelt mit einem Lösungsmittel, zum Beispiel Äther, aus. Nach dem Abdestillieren des Lösungsmittels hin terbleibt das Sulfon als gelbliches Öl.
Process for making a sulfone. It has been found that a new sulfone is obtained when a salt of p-toluenesulfuric acid is reacted with an ethyl α-halo laurate.
The new sulfone forms a yellowish oil that is supposed to be used as an intermediate product.
<I> Example: </I> 25 parts by weight of a-bromauric acid ethyl ester are kept at 150-160 for about 11 hours in a stirred autoclave with an amount of sodium toluenesulfinic acid equivalent to 17.4 parts by weight of pure sulfinate, and 90 parts by volume of ethyl alcohol . The reaction product is then diluted with water and extracted with a solvent, for example ether. After the solvent has been distilled off, the sulfone remains as a yellowish oil.
