Description

  

  Zusatzpatent zum Hauptpatent Nr. 248209.    Verfahren     zur    Herstellung eines neuen     Halbesters.       Es wurde gefunden,     ,dass    man zu einem  neuen Halbester gelangt, wenn man 1     Mol          'L'-(_f-Oxyäthyl)-ölsäureamid    mit 1     Mol        Malein-          säure    oder     iXaleinsäureanhydrid    umsetzt.  



  Es ist vorteilhafter,     Maleinsäureanhydrid     als     Maleinsäure    selbst zu verwenden.  



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



  Das     Natriumsalz    des neuen Halbesters bil  det eine feste Masse, die von Wasser zu einer  klaren, schäumenden Lösung aufgenommen  wird. Es kann als Textilhilfsmittel, z. B. als       Weichmachungsmittel    für     Cellulosefasern,     verwendet werden.    <I>Beispiel:</I>  32,5 Teile N-     (fl-        Oxyäthyl)    -     ölsäureamid     und 9,8 Teile     Maleinsäureanhydrid    werden  bei 95 bis 100  so lange verrührt, bis sich    eine     mitNatriumhydro@xydlösung    neutralisierte  Probe klar in Wasser löst, was nach einigen  Stunden der Fall ist.

   Man löst den erhaltenen  Halbester der     Maleinsäure    in Äthylalkohol;  neutralisiert mit     Natriumhydroxydlösung    und  dampft zur Trockne ein: Der so erhaltene  Rückstand bildet eine feste Masse, die von  Wasser zu einer klaren, schäumenden Lösung  aufgenommen wird. Das neue     Natriumsalz     kann als Textilhilfsmittel, z. B. als Weich  machungsmittel für     Cellülosefa@sern,    verwen  det werden.



  Additional patent to main patent No. 248209. Process for the production of a new half-ester. It has been found that a new half-ester is obtained if 1 mol of 'L' - (_ f-oxyethyl) oleic acid amide is reacted with 1 mol of maleic acid or iXaleic anhydride.



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



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



  The sodium salt of the new half ester forms a solid mass that is absorbed by water to form a clear, foaming solution. It can be used as a textile auxiliary, e.g. B. can be used as a softener for cellulose fibers. <I> Example: </I> 32.5 parts of N- (fl- oxyethyl) - oleic acid amide and 9.8 parts of maleic anhydride are stirred at 95 to 100 until a sample neutralized with sodium hydroxide solution dissolves clearly in water, which is the case after a few hours.

   The half-ester of maleic acid obtained is dissolved in ethyl alcohol; neutralized with sodium hydroxide solution and evaporated to dryness: the residue obtained in this way forms a solid mass which is taken up by water to form a clear, foaming solution. The new sodium salt can be used as a textile auxiliary, e.g. B. as a plasticizing agent for Cellülosefa @ fibers, are used.
