Description

  

  Verfahren zur Herstellung eines neuen Kondensationsproduktes.    Es wurde gefunden, dass man zu einem  neuen Kondensationsprodukt gelangt, wenn  man das Gemisch der     a-Chlormethyläther     aus der handelsüblichen Mischung aus vor  wiegend     Octadecylalkohol    und einer gerin  geren Menge     Hexadecylalkohol    auf     Thio-          harnstoff        einwirken    lässt.  



  Die Umsetzung wird zweckmässig in  Gegenwart eines Lösungsmittels, wie Benzol,  Aceton, vorgenommen.  



  Das neue Kondensationsprodukt bildet in  Form des Chlorhydrats ein farbloses Pulver,  das von warmem Wasser zu einer beim       Schütteln    stark schäumenden Lösung auf  genommen wird. Es eignet sich insbesondere  zum     Wasserfestmachen    von Textilien.

      <I>Beispiel:</I>  Eine handelsübliche Mischung aus vor  wiegend     Octadecylalkohol    und     einer    gerin  geren Menge     Hexadecylalkohol    wird     in    übli  cher Weise     in    den     a-Chl.ormethyläther    Über  geführt. 25 Gewichtsteile des so erhaltenen       a-Chlormethyläthers,        gp.3    185 bis<B>188',</B> wer  den in 77     Gewichtsteilen    trockenem Benzol  gelöst.

   Man fügt 6,4     Gewichtsteile    fein pul  verisierten     Thioharnstoff    unter     raschexri    Rüh  ren hinzu und erhitzt sodann etwa 1     Stunde     auf 75  , wobei für eine gute     Durchmischung     Sorge zu tragen ist. Nach dem Abkühlen  wird das ausgefallene     Kondensationsprodukt,     dem aller Wahrscheinlichkeit nach die       Formel     
EMI0001.0025     
    zuzuschreiben ist, von der Mutterlauge ge  trennt, mit Benzol gewaschen und bei nied  riger Temperatur vom anhaftenden Lösungs-    mittel befreit. Man erhält ein farbloses Pul  ver, das von warmem Wasser zu einer beim  Schütteln stark schäumenden Lösung auf-      genommen wird.

   Das neue Kondensations  produkt eignet sich insbesondere zum Was  serabstossendmachen von Textilien. Eine  waschechte     Hydrophobierung    wird bereits er  zielt, Renn das mit der wässerigen Lösung  getränkte Gewebe, beispielsweise aus Baum  wolle, bei etwa 75   getrocknet wird.



  Process for the production of a new condensation product. It has been found that a new condensation product is obtained if the mixture of α-chloromethyl ethers from the commercial mixture of predominantly octadecyl alcohol and a smaller amount of hexadecyl alcohol is allowed to act on thiourea.



  The reaction is expediently carried out in the presence of a solvent such as benzene or acetone.



  The new condensation product forms a colorless powder in the form of the chlorohydrate, which is absorbed by warm water to form a strongly foaming solution when shaken. It is particularly suitable for making textiles waterproof.

      <I> Example: </I> A commercial mixture of predominantly octadecyl alcohol and a smaller amount of hexadecyl alcohol is converted into the α-chloromethyl ether in the usual way. 25 parts by weight of the α-chloromethyl ether obtained in this way, gp.3 185 to 188 ', who dissolved the in 77 parts by weight of dry benzene.

   6.4 parts by weight of finely powdered thiourea are added with rapid stirring and then heated to 75 for about 1 hour, care being taken to ensure thorough mixing. After cooling, the precipitated condensation product, which in all likelihood has the formula
EMI0001.0025
    is to be attributed, separated from the mother liquor, washed with benzene and freed from adhering solvent at low temperature. A colorless powder is obtained which is absorbed by warm water to form a solution which foams strongly when shaken.

   The new condensation product is particularly suitable for making textiles water-repellent. A real water-repellent treatment is already being achieved, if the fabric soaked with the aqueous solution, for example made of cotton, is dried at around 75.
