Description

  

      Verfahren    zur Herstellung eines neuen     Harnstoffderivates.            Es    wurde     gefunden,    dass man zu einem  neuen     Harnstoffderivat    gelangt, wenn man  1     Mol    Formaldehyd in     Gegenwart    einer  Säure auf 2     Mol    des     Kondensationsproduktes          aus    1     Mol        Stearinsäure-N-methylolamid    und  1 Mal     Harnstoff        einwirken    lässt.  



  Das als Ausgangsstoff dienende Kon  densationsprodukt aus 1     Mol        Stearinsäure-          N-methylolamid    kann z. B. nach dem Ver  fahren der schweizerischen Patentschrift  Nr. 210976 hergestellt werden.  



  Als Säure wird beim vorliegenden Ver  fahren vorteilhaft     konzentrierte    Schwefel  säure verwendet. Die erfindungsgemässe     Um-          setzurig        wird    zweckmässig in Gegenwart eines       Lösungsmittels,    z. B. unter Zusatz von Eis  essig, ausgeführt, vorteilhaft bei etwa 100       bis    110  C.  



  Das     Verfahrenserzeugnis    bildet ein gelbes  Pulver, das als     Textilbilfsstoff        verwendet     werden     kann..     



  <I>Beispiel:</I>  35,5 Teile des     Kondensationsproduktes     aus     Stearinsäuremethylolamid    und Harnstoff,       das    der wahrscheinlichen Formel       C"g"        CO-Ng=CH2-NH-CO-NHZ     entspricht,     und    welches z. B. nach dem Ver  fahren der schweizerischen Patentschrift  Nr. 210976     erhalteh    werden kann, werden in  350 Teilen Eisessig gelöst.

   Unter Rühren  trägt man zuerst 1,7 Teile     Paraformaldehyd     ein.     Dann    werden 5 Teile konzentrierte  Schwefelsäure zugegeben und die klare Lö-         sung        wird    während 90     Minuten    unter Rück  fluss gekocht. Das Reaktionsprodukt, eine       Methylenverbindung    der wahrscheinlichen  Formel  
EMI0001.0041     
    kann durch Eintragen des     Reaktionsgemisches     in Wasser als gelblich gefärbtes Pulver ab  geschieden werden.



      Process for the production of a new urea derivative. It has been found that a new urea derivative is obtained if 1 mol of formaldehyde is allowed to act in the presence of an acid on 2 mol of the condensation product of 1 mol of stearic acid-N-methylolamide and once urea.



  The condensation product used as starting material from 1 mole of stearic acid N-methylolamide can, for. B. after the process of the Swiss patent No. 210976 can be produced.



  In the present process, the acid used is advantageously concentrated sulfuric acid. The implementation according to the invention is expediently carried out in the presence of a solvent, e.g. B. with the addition of glacial vinegar, carried out, advantageously at about 100 to 110 C.



  The process product forms a yellow powder that can be used as a textile improver ..



  <I> Example: </I> 35.5 parts of the condensation product of stearic acid methylolamide and urea, which corresponds to the probable formula C "g" CO-Ng = CH2-NH-CO-NHZ, and which z. B. according to the process of Swiss patent no. 210976 can be obtained, glacial acetic acid are dissolved in 350 parts.

   1.7 parts of paraformaldehyde are first introduced with stirring. Then 5 parts of concentrated sulfuric acid are added and the clear solution is refluxed for 90 minutes. The reaction product, a methylene compound of the likely formula
EMI0001.0041
    can be deposited as a yellowish colored powder by adding the reaction mixture in water.
