Description

  

  Verfahren zur Herstellung eines neuen     1)iaeyldervates.       Es wurde gefunden, dass man zu einem  neuen     Diacylderivat    gelangt, wenn man 1     Mol          2,3-Dioxy-propansulfonsäure-(1)    der Formel  
EMI0001.0005     
    mit 2     Mol    einer den Rest  
EMI0001.0007     
    abgebenden Verbindung umsetzt.  Als eine den Rest  
EMI0001.0008     
    abgebende Verbindung kann man z.

   B.     Capryl-          säure,    ihr     Anhydrid    oder ein     Caprylsäure-          halogenid    oder ferner einen Ester der     Capryl-          säure    mit einem     niedrigmolekularen    Alkohol  verwenden.    Die Umsetzung erfolgt zweckmässig bei  höherer     Temperatur    und, falls man von     Capryl-          säure    ausgeht, vorteilhaft unter vermindertem  Druck.

   Wird ein     Caprylsäurehalogenid    zur       Umsetzung    herangezogen, so arbeitet man vor  zugsweise in Gegenwart eines     säurebindenden     Mittels, z. B. unter Zusatz von     Pyridin.     



  Das     Natriumsalz    der neuen, mit     Capryl-          säure        diacylierten        2,3-Dioxy-propansulfon-          säure-(1)    bildet eine feste Masse, die von  Wasser zu einer stark schäumenden Lösung  von hervorragender Netzwirkung aufgenommen  wird. Es kann als     Textilhilfsstoff,    z. B. als  Netzmittel, angewendet werden.  



       Beispiel:     Man lässt 16,2     Gew.-Teile        Caprylsäure-          chlorid    unter Rühren langsam zu einer Mi  schung von 20     Vol.-Teilen        Pyridin    und 8,9       Gew.-Teilen        Natriumsalz    der     2,3-Dioxy-pro-          pansulfonsäure-(1)        hinzugiessen,    steigert die  Temperatur langsam auf     95-100     und rührt  anschliessend etwa 2 Stunden bei der an  gegebenen Temperatur.

   Das mit Natrium-           hydroxydlösung    neutral gestellte Umsetzungs  produkt wird darauf zur Trockne verdampft,  vorteilhaft unter vermindertem Druck. Der  Rückstand stellt eine feste Masse dar, die  von Wasser zu einer stark     schäumenden    Lö  sung von hervorragender Netzwirkung auf  genommen wird.



  Process for the production of a new 1) iaeyldervate. It has been found that a new diacyl derivative is obtained if 1 mole of 2,3-dioxy-propanesulfonic acid- (1) of the formula
EMI0001.0005
    with 2 moles one the rest
EMI0001.0007
    transferring connection. As one the rest
EMI0001.0008
    delivering connection can be z.

   B. use caprylic acid, its anhydride or a caprylic acid halide or an ester of caprylic acid with a low molecular weight alcohol. The reaction is expediently carried out at a higher temperature and, if one starts from caprylic acid, advantageously under reduced pressure.

   If a caprylic acid halide is used for the reaction, it is preferably carried out in the presence of an acid-binding agent, eg. B. with the addition of pyridine.



  The sodium salt of the new 2,3-dioxy-propanesulfonic acid- (1) diacylated with caprylic acid forms a solid mass which is absorbed by water to form a strongly foaming solution with excellent wetting effect. It can be used as a textile auxiliary, e.g. B. can be used as a wetting agent.



       Example: 16.2 parts by weight of caprylic acid chloride are slowly added with stirring to a mixture of 20 parts by volume of pyridine and 8.9 parts by weight of the sodium salt of 2,3-dioxy-propanesulfonic acid (1 ) Pour in, the temperature slowly increases to 95-100 and then stirred for about 2 hours at the given temperature.

   The reaction product, which has been rendered neutral with sodium hydroxide solution, is then evaporated to dryness, advantageously under reduced pressure. The residue is a solid mass that is taken up by water to form a strong foaming solution with excellent wetting effect.
