Description

  

  Verfahren zur Herstellung eines neuen     Amidderivates.       Es wurde gefunden, dass man zu einem  neuen     Amidderivat    ,gelangt,     wenn    man tech  nisches     Stearinsäureamid,    Formaldehyd und  ein     Gemisch    von     glykolsaurem    Natrium und  Kochsalz, wie man es durch     Einwirkung    von       Natriumcarbonat    auf Chloressigsäure erhält,  aufeinander einwirken     lässt.     



  Die Umsetzung wird zweckmässig in Ge  genwart eines     Lösungsmittels    und vorteilhaft  unter Zusatz einer Säure ausgeführt, z. B. in  Anwesenheit von Eisessig, welcher gleich  zeitig     als    Lösungsmittel wirkt.  



  Das     Natriumsalz    des neuen     Amidderiva-          tes    bildet ein weisses Pulver, das in Wasser  löslich     ist.    Es kann als Textilhilfsmittel, z. B.  als     Mittel    zum     Wasserabstossendmachen    von       Textilien,    verwendet werden.  



  <I>Beispiel:</I>  360 Teile technisches     Stearinsäureamid     werden in 300     Volumteilen    Eisessig gelöst.  Bei 75-80  werden unter ,gutem Rühren 428  Teile eines     Gemisches    von     glykols.aurem    Na  trium und Kochsalz,     wie    es<B>,</B> durch Umsetzung    von Chloressigsäure mit     Natriumhydroxyd     oder     Natriumcarbonat    erhalten wird, und 120  Teilen     Paraformaldehyd    zugegeben.

   Nach  15stündigem Rühren wird die dickflüssige  Masse zu     einer    Lösung von 900 Teilen     Na-          triumcarbonat    in 6000     Teilen        destilliertem     Wasser unter Rühren     zufliessen    gelassen. Die  Temperatur soll unter 20  gehalten werden.  Nachdem alles eingetragen ist, wird eine  Stunde bei Raumtemperatur gerührt, auf 70   erhitzt und 900 Teile     Natriumchlorid    zu  gegeben. Bei weiterem Erhitzen auf 90-95   scheidet sich das Umsetzungsprodukt ab: Es  kann durch Filtration isoliert werden und  stellt nach dem Trocknen ein weisses Pulver  dar, das in Wasser löslich ist.



  Process for the preparation of a new amide derivative. It has been found that a new amide derivative is obtained if technical stearic acid amide, formaldehyde and a mixture of sodium glycolate and common salt, as obtained by the action of sodium carbonate on chloroacetic acid, are allowed to act on one another.



  The reaction is conveniently carried out in the presence of a solvent and advantageously with the addition of an acid, e.g. B. in the presence of glacial acetic acid, which also acts as a solvent.



  The sodium salt of the new amide derivative forms a white powder that is soluble in water. It can be used as a textile auxiliary, e.g. B. can be used as a means for making textiles water repellent.



  <I> Example: </I> 360 parts of technical stearic acid amide are dissolved in 300 parts by volume of glacial acetic acid. At 75-80, 428 parts of a mixture of glycolic acid sodium and common salt, as is obtained by reacting chloroacetic acid with sodium hydroxide or sodium carbonate, and 120 parts of paraformaldehyde are added with thorough stirring.

   After stirring for 15 hours, the viscous mass is allowed to flow into a solution of 900 parts of sodium carbonate in 6000 parts of distilled water with stirring. The temperature should be kept below 20. After everything has been entered, the mixture is stirred for one hour at room temperature, heated to 70 and 900 parts of sodium chloride are added. The reaction product separates out on further heating to 90-95: It can be isolated by filtration and, after drying, is a white powder that is soluble in water.
