Description

  

  Verfahren zur Herstellung eines neuen     Amidabkömmlings.       Es wurde gefunden, dass man zu einem  neuen     Amidabkömmling    gelangt, wenn man  1     Mol        Octadecylurethan    mit 1     Mol        Croton-          aldehyd    und 2     Mol        Natriumbisulfit    umsetzt.  



  Die     Umsetzung    kann z. B. bei 100 bis  200 , vorteilhaft in Gegenwart eines Lö  sungsmittels,     wie        Diäthylenglykol    oder     N-          I'ormylmorpholin,    vorgenommen werden. Im  allgemeinen ist es zweckmässig, die verfah  rensgemässe     Umsetzung    in Gegenwart von ge  ringen     Mengen    eines sekundären     Amins    oder  eines entsprechenden Salzes, z.

   B. unter Zu  satz von     Piperidin,        Diisoamylamin    oder     Di-          äthanalamin,        vorzunehmen.    Auf diese Weise  kann die     Reaktionsgeschwindigkeit    erhöht  werden.  



  Das neue     Erzeugnis,    eine gelblich ge  färbte     Masse,        wird    von Wasser zu einer kla  ren,     schäumenden    Lösung     aufgenommen.    Es  kann als     Tegtilhilfssstoff,    z. B. als Wasch  mittel, angewendet werden.

           Beispiel:     Zu     einer    Lösung von 6,2 Teilen     Octa-          decylurethan    in 15 Teilen     Diäthylenglykol     werden bei 80     bie    90  unter Rühren 1,8     Teeile          Crotonaldehyd,    5 Teile     pulverisiertes        Na-          triumbisulfit    und 0,1 Teil     Piperidin    ge  geben. Nach     zweistündigem    Erhitzen auf       130        biss    140  ist eine Probe in Wasser klar    löslich.

   Das     DiäthylenglykolwhdRwhd    mit Ace  ton ausgezogen     und    der     Rückstand    im Va  kuum vom Aceton     befreit.    Es wird eine, gelb  lich gefärbte, weiche     Masse    erhalten, die in  Wasser klar löslich ist.



  Process for the preparation of a new amide derivative. It has been found that a new amide derivative is obtained if 1 mole of octadecyl urethane is reacted with 1 mole of croton aldehyde and 2 moles of sodium bisulfite.



  The implementation can e.g. B. at 100 to 200, advantageously in the presence of a Lö solvent such as diethylene glycol or N-I'ormylmorpholine, are made. In general, it is advantageous to carry out the procedural reaction in the presence of small amounts of a secondary amine or a corresponding salt, eg.

   B. with the addition of piperidine, diisoamylamine or diethanalamine. In this way, the reaction speed can be increased.



  The new product, a yellowish colored mass, is absorbed by water to form a clear, foaming solution. It can be used as Tegtilhilfssstoff such. B. be used as a detergent.

           Example: 1.8 parts of crotonaldehyde, 5 parts of powdered sodium bisulfite and 0.1 part of piperidine are added to a solution of 6.2 parts of octadecyl urethane in 15 parts of diethylene glycol at 80 to 90 with stirring. After two hours of heating to 130 to 140, a sample is clearly soluble in water.

   The diethylene glycol whdRwhd extracted with acetone and the residue freed from acetone in a vacuum. It is a, yellow Lich colored, soft mass obtained, which is clearly soluble in water.
