Description

  

      Verfahren    zur Herstellung eines neuen     Halbesters.       Es     wurde    gefunden, dass man zu einem  neuen     Halbester        gelangt,    wenn man 1     Mol          N-(ss-Ozyäthyl)-stearinsäureamid    mit 1     Mol          Maleinsäure    oder     Maleinsäureanhydrid    um  setzt.  



  Es ist vorteilhafter,     Maleinsäureanhydrid     als     Maleinsäure    selbst zu verwenden.  



  Die Umsetzung wird zweckmässig in der  Wärme, z. B. bei 90-120 , vorgenommen.  Wenn man     Maleinsäure    als Ausgangsstoff  verwendet, ist es vorteilhaft, unter Zusatz  einer     geringen    Menge einer starken Säure mit  dem     N-(ss-Oxyäthyl)-stearinsäureamid    zu er  hitzen, bis 1     Mol    Wasser abgespalten ist.  



  Das     Natriumsalz    des neuen     Halbesters    ist  ein annähernd farbloses Pulver, das von Was  ser zu einer klaren, schäumenden Lösung  aufgenommen wird. Es kann als     Textilhilfs-          stoff,    z. B. als     Weichmachungsmittel,    An  wendung finden.  



       Beispiel:     82,5 Teile     N-(ss-Oxyäthyl)-stearinsäure-          amid    und 9,8 Teile     Maleinsäureanhydrid    wer  den bei     95-100"    so lange verrührt, bis sieh  eine mit     Natriumhydroxydlösung    neutrali  sierte Probe in Wasser klar löst. Dies ist nach  etwa     ä    Stunden der Fall.

   Der so     erhaltene     saure Ester der     Maleinsäure    wird anschlie  ssend durch     Neutralisieren    mit     Natriumhydro-          xyd    oder     Natriumcarbonat    in das Natrium-    salz     übergeführt,        vorteilhaft    nach vorheri  gem Lösen     in        Äthylalkohol.    Nach dem Trock  nen bildet das     Natriumsalz    des neuen     Halb-          esters    ein annähernd farbloses Pulver, das  von Wasser zu einer klaren,

   schäumenden  Lösung aufgenommen     wird.    Es kann als     Tex-          tilhilfsstoff,    z. B. als sehr     wirksames    Weich  machungsmittel für     Zellulosefasern,    verwen  det werden. Für diesen Zweck eignet sich  z. B.     eine        Mischung    aus 70 Teilen des obigen       Natriumsalzes    und 30 Teilen     Dinatriumsalz     der     N-Benzyl-,u-hepta,decyl-benzimidazol-di-          sulfonsäure.  



      Process for the production of a new half-ester. It has been found that a new half-ester is obtained if 1 mole of N- (ss-Ozyäthyl) stearic acid amide is reacted with 1 mole of maleic acid or maleic anhydride.



  It is more beneficial to use maleic anhydride than maleic acid itself.



  The implementation is expediently in the heat, for. At 90-120. If maleic acid is used as the starting material, it is advantageous, with the addition of a small amount of a strong acid with the N- (ss-oxyethyl) stearic acid amide, to heat it until 1 mole of water has been split off.



  The sodium salt of the new half ester is an almost colorless powder that is absorbed by water to form a clear, foaming solution. It can be used as a textile auxiliary, e.g. B. as a plasticizer, to find application.



       Example: 82.5 parts of N- (ss-oxyethyl) stearic acid amide and 9.8 parts of maleic anhydride are stirred at 95-100 "until a sample neutralized with sodium hydroxide solution dissolves clearly in water. This is after the case for about a hour.

   The acid ester of maleic acid obtained in this way is then converted into the sodium salt by neutralization with sodium hydroxide or sodium carbonate, advantageously after prior dissolution in ethyl alcohol. After drying, the sodium salt of the new half-ester forms an almost colorless powder that changes from water to a clear,

   foaming solution is added. It can be used as a textile auxiliary, e.g. B. can be used as a very effective plasticizing agent for cellulose fibers. For this purpose z. B. a mixture of 70 parts of the above sodium salt and 30 parts of the disodium salt of N-benzyl-, u-hepta, decyl-benzimidazole-disulfonic acid.
