Description
Verfahren zur Herstellung eines neuen Textilhilfsstoffes. Es wurde gefunden, dass man ein neues, als Tegtilhilfsstoff besonders wertvolles Pro dukt erhält, wenn man ein Salz der p-To- luolsulfinsäure mit einem in a-Stellung halo- genierten Laurinsäureäthylester umsetzt und das so erhaltene Sulfon mit Sulfonierungs- mitteln behandelt.
Die neue Sulfonsäure bildet in Form ihres Natriumsalzes ein Pulver, welches eine gute Waschkraft besitzt.
<I>Beispiel: ,</I> 25 Gewichtsteile a-Bromlaurinsäureäthyl- ester werden mit einer solchen Menge toluol- sulfinsaurem Natrium, als 17,4 Gewichtstei len reinem Sulfinat entspricht, und 90 Raum teilen Äthylalkohol während etwa 11 Stun den in einem Rührautoklaven auf 150 bis 160 C gehalten. Man verdünnt darauf das Reaktionsprodukt mit Wasser und schüttelt mit einem Lösungsmittel, zum Beispiel Äther, aus. Nach dem Abdestillieren des Lösungsmittels hinterbleibt das Sulfon als gelbliches Öl.
Zur Sulfonierung lässt man 15 Gewichts teile des so erhaltenen Sulfons unter Küh lung in 30 Gewichtsteile Chlorsulfonsäure einlaufen und fügt darauf 30 Gewichtsteile rauchende Schwefelsäure mit einem Schwe- feltriogydgehalt von etwa 64% allmählich hinzu, wobei man die Temperatur unter etwa <B>10'</B> C hält. Man lässt hierauf die Tempera tur auf 30 C steigen und rührt bei Zimmer temperatur bis das Reaktionsprodukt in Wasser löslich ist.
Trägt man nach beendig ter Sulfonierung das Reaktionsgemisch auf wenig Eis aus, so lässt sich die entstandene Sulfonsäure bei genügender Abkühlung von der verdünnten Schwefelsäure abtrennen. Man neutralisiert dieselbe und dampft zur Trockne ein.
Process for the production of a new textile auxiliary. It has been found that a new product which is particularly valuable as a Tegtil auxiliary is obtained if a salt of p-toluenesulfinic acid is reacted with an ethyl laurate halogenated in the α-position and the sulfone thus obtained is treated with sulfonating agents.
The new sulfonic acid forms a powder in the form of its sodium salt, which has good detergency.
<I> Example: </I> 25 parts by weight of a-bromolauric acid ethyl ester are mixed with sodium toluenesulfinate in such an amount as 17.4 parts by weight corresponds to pure sulfinate, and 90 parts by weight of ethyl alcohol are in a stirred autoclave for about 11 hours held at 150 to 160 C. 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.
For sulfonation, 15 parts by weight of the sulfone obtained in this way are run into 30 parts by weight of chlorosulfonic acid with cooling, and 30 parts by weight of fuming sulfuric acid with a sulfur trihydrate content of about 64% are gradually added, the temperature being below about 10% / B> C holds. The temperature is then allowed to rise to 30 ° C. and the mixture is stirred at room temperature until the reaction product is soluble in water.
If the reaction mixture is discharged onto a little ice after the sulfonation has ended, the sulfonic acid formed can be separated off from the dilute sulfuric acid with sufficient cooling. It is neutralized and evaporated to dryness.
