Description

  

  Verfahren zur Herstellung eines neuen     Thioharnstoffderivates.       Es wurde gefunden, dass man zu einem  neuen     Thioharnstoffderivat    gelangt, wenn  man p -     Stearoylamino    -     benzoylchlorid    mit       Allylthioharnstoff    umsetzt. .  



  Die Umsetzung mit dem     Allylthioharn-          stoff    wird zweckmässig in Gegenwart eines  Lösungsmittels, wie     Aceton,    vorgenommen.  



  Das neue     Thioharnstoffderivat    stellt eine       pulverisierbare,    schwach gelbliche Masse dar,  die von Wasser leicht zu einer klaren, stark  schäumenden und beim Erhitzen sich     unter     Verlust der Schaumfähigkeit trübenden Lö  sung aufgenommen wird. Das neue Produkt  kann als     Textilhilfsmittel,    z. B. zum Wasser  abstossendmachen,     verwendet    werden.  



       Beispiel:     4,2 Gewichtsteile     p-Stearoylamino-ben-          zoylchlorid,    hergestellt durch Behandeln von       p-Stearylamino-benzoesäure    mit überschüssi  gem     Thionylchlorid    in der Wärme und Ab  destillieren des     überschüssigen    Thionylchlo-         rids    im Vakuum, werden in 20     Volumteilen     Aceton gelöst. Zu dieser auf<B>10'</B> abgekühlten  Lösung wird eine ebenfalls abgekühlte Lö  sung von 2 Gewichtsteilen     Allylthioharnstoff     in 10     Volumteilen    Aceton gegeben.

   Das Kon  densationsprodukt scheidet sich bald als an  fänglich harzige, gelbliche Masse aus. Nach  dem Abtrennen des Acetons     und    Trocknen  des Produktes im Vakuum erhält man ein       pulverisierbares,    schwach gelbliches, in Was  ser leicht lösliches Produkt. Die klare wäs  serige Lösung schäumt stark und wird nach  kurzem Erhitzen trübe unter Verlust der  Schaumfähigkeit.



  Process for the preparation of a new thiourea derivative. It has been found that a new thiourea derivative is obtained if p - stearoylamino - benzoyl chloride is reacted with allyl thiourea. .



  The reaction with the allyl thiourea is expediently carried out in the presence of a solvent such as acetone.



  The new thiourea derivative is a pulverizable, pale yellowish mass that is easily absorbed by water to form a clear, strongly foaming solution that becomes cloudy when heated and loses its foamability. The new product can be used as a textile auxiliary, e.g. B. to make water repellent.



       Example: 4.2 parts by weight of p-stearoylamino-benzoyl chloride, prepared by treating p-stearylamino-benzoic acid with excess thionyl chloride in the heat and distilling off the excess thionyl chloride in vacuo, are dissolved in 20 parts by volume of acetone. A likewise cooled solution of 2 parts by weight of allyl thiourea in 10 parts by volume of acetone is added to this solution, which has been cooled to <B> 10 '</B>.

   The condensation product soon separates out as an initially resinous, yellowish mass. After separating off the acetone and drying the product in vacuo, a pulverizable, pale yellowish product which is easily soluble in what water is obtained. The clear aqueous solution foams vigorously and, after brief heating, becomes cloudy with loss of foamability.
