Description

  

  Verfahren<B>zur</B> Herstellung eines neuen     Diaeylderirats.       Es wurde gefunden, dass man zu einem  neuen     Diacylderivat    gelangt, wenn man 1     Mol          2,3-Dioxypropansulfonsäure-(1)    der Formel  
EMI0001.0005     
    mit 2     Mol        einer    den Rest  
EMI0001.0008     
    abgebenden Verbindung umsetzt.  Als eine den Rest  
EMI0001.0009     
    abgebende Verbindung kann man z.

   B:     Capron-          säure,    ihr     Anhydrid    oder ein     Capronsäure-          halogenid    oder ferner einen Ester der     Capron-          säure    mit einem     niedrigmolekularen        Alkohol     verwenden.  



  Die Umsetzung erfolgt zweckmässig bei  höherer Temperatur und, falls man von Capron-    säure ausgeht, vorteilhaft unter     vermindertem     Druck. Wird ein     Capronsäurehalogenid    zur  Umsetzung herangezogen, so arbeitet man  vorzugsweise in Gegenwart eines säurebin  denden Mittels, z. B. unter Zusatz von     Pyridin.     



  Das     Nätriumsalz    der neuen     2,3-Di-(caproyl-          oxy)-propansulfonsäure-(1)    bildet eine feste  Masse, die von Wasser zu einer     klaren    Lösung  von hoher     Schaumkraft    aufgenommen wird.  Es kann als     Textilhilfsmittel,    z. B: als Schaum  mittel, Anwendung finden.  



  <I>Beispiel:</I>  Man lässt 13,4     Gew.-Teile        Capronsäure-          chlorid    unter Rühren langsam zu einer Mi  schung von 20     Vol.-Teilen        Pyridin    und 8,9       Gew.-TeilenNatriumsalz    der     2,3-Dioxypropan-          sulfonsäure-(1)        hinzufliessen,    steigert die Tem  peratur langsam auf 95-100  und rührt an  schliessend etwa 2 Stunden bei der angegebenen  Temperatur.

   Das Umsetzungsgut     wird    darauf  mit     Natriumhydroxydlösung    neutralisiert und  zur Trockne verdampft,     zweckmässig    unter  vermindertem Druck.     Klan    erhält     eine    feste      Masse, die von Wasser zu einer klaren Lösung  von hoher     Schaumkraft    aufgenommen wird.



  Process <B> for </B> production of a new dialylderirate. It has been found that a new diacyl derivative is obtained if 1 mol of 2,3-dioxypropanesulfonic acid- (1) of the formula
EMI0001.0005
    with 2 moles one the rest
EMI0001.0008
    transferring connection. As one the rest
EMI0001.0009
    delivering connection can be z.

   B: Use caproic acid, its anhydride or a caproic acid halide or an ester of caproic acid with a low molecular weight alcohol.



  The reaction is expediently carried out at a higher temperature and, if you start from caproic acid, advantageously under reduced pressure. If a caproic acid halide is used for the reaction, it is preferably carried out in the presence of an acid-binding agent such. B. with the addition of pyridine.



  The sodium salt of the new 2,3-di- (caproyl-oxy) -propanesulfonic acid- (1) forms a solid mass which is absorbed by water to form a clear solution with high foaming power. It can be used as a textile auxiliary, e.g. B: as a foam agent, used.



  <I> Example: </I> 13.4 parts by weight of caproic acid chloride are slowly added to a mixture of 20 parts by volume of pyridine and 8.9 parts by weight of the sodium salt of 2,3-dioxypropane, while stirring Add sulfonic acid (1), the tem perature increases slowly to 95-100 and then stirred for about 2 hours at the specified temperature.

   The reaction mixture is then neutralized with sodium hydroxide solution and evaporated to dryness, advantageously under reduced pressure. Klan receives a solid mass that is absorbed by water to form a clear solution with high foaming power.
