Description

  

  Verfahren zur Herstellung eines neuen     Sulfaminsäurederivates.       Es     wurde        gefunden,    dass man zu einem  neuen     Sulfaminsäurederivat    gelangt, wenn  man     Stearinsäuremethylolamid    in Gegenwart  einer Säure mit     sulfaminsaurem    Natrium  umsetzt.  



  Die Umsetzung wird zweckmässig in Ge  genwart eines Lösungsmittels, wie Methanol,  Aceton oder Eisessig, vorgenommen. Als  Säure kann beispielsweise Chlorwasserstoff,  Schwefelsäure oder Essigsäure     Anwendung     finden.  



  Das neue     Sulfaminsäurederivat    bildet ein  weisses Pulver, welches von heissem Wasser  zu einer klaren Lösung von gutem Wasch  vermögen aufgenommen wird. Es kann als       Tegtilhilfsstoff,    z. B. als Waschmittel, An  wendung finden.  



  <I>Beispiel:</I>  12 Gewichtsteile     Stearinsäuremethylol-          amid    werden mit 7 Teilen     sulfaminsaurem     Natrium und 30     Volumteilen    Eisessig  während 12     Stunden    unter Rühren auf 60  bis 65  erwärmt.     Hierauf        wird    der Eisessig  im Vakuum     abdestilliert    und der     Rückstand       durch     Umkristallisieren        aus    wässerigem Al  kohol gereinigt. Man erhält ein weisses       Pulver,    welches sich in heissem Wasser klar  löst. Die wässerige Lösung besitzt ein gutes  Waschvermögen.



  Process for the preparation of a new sulfamic acid derivative. It has been found that a new sulfamic acid derivative is obtained if stearic acid methylolamide is reacted with sulfamic acid sodium in the presence of an acid.



  The reaction is expediently carried out in the presence of a solvent such as methanol, acetone or glacial acetic acid. Hydrogen chloride, sulfuric acid or acetic acid, for example, can be used as the acid.



  The new sulfamic acid derivative forms a white powder, which is absorbed by hot water to a clear solution of good washing capacity. It can be used as a Tegtilhilfsstoff, z. B. as a detergent, to find application.



  <I> Example: </I> 12 parts by weight of stearic acid methylolamide are heated with 7 parts of sulfamic acid sodium and 30 parts by volume of glacial acetic acid to 60 to 65 for 12 hours while stirring. The glacial acetic acid is then distilled off in vacuo and the residue is purified by recrystallization from aqueous alcohol. A white powder is obtained which dissolves clearly in hot water. The aqueous solution has good detergency.
