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.
