      Ziisatzpateitit    zum Hauptpatent     Nr.   <B>158243.</B>    Verfahren zur Darstellung einer     hochmolektilaren        Sulfosätire.       Es wurde gefunden,     dass    man zu neuen  wasserlöslichen Kondensationsprodukten     ge-          lan-en    kann, wenn man feste, sauer konden  sierte Kunstharze auf     FormaIdeliydbasis     einer     Behandlun   <B>'--</B> mit Phenol, seinen Homo  logen oder     Substitutionsprodukten    unterwirft  und die entstehende homogene Masse mit sul  fonierenden Mitteln behandelt.  



  Vorliegende, Erfindung bezieht sich nun  auf ein Verfahren zur Darstellung einer  hochmolekularen     Sulfosäure,    dadurch ge  kennzeichnet,     dass    man ein durch Kondensa  tion eines technischen Gemisches von o- und       p-Chlorphenol    und Harnstoff mit Formal  dehyd unter     Mitverwendung    von sauren Kata  lysatoren erhaltenes Kunstharz in einem  technischen Gemisch von o- und     p-Chlo-r-          phenol    löst und bis zur Wasserlöslichkeit mit  .sulfonierenden Mitteln behandelt.  



  Der neue Körper stellt in Form seines       Alkalisalzes    eine schwach gefärbte, amorphe  Masse dar. Ausser als Gerbstoff kann das  Produkt als     Wollreservieruno-smittel    in der  <B><I>k3</I></B>       Halbwollfärberei    dienen.    <I>Beispiel:</I>  <B>8,6</B> Teile eines Harzes erhalten durch  Kondensation von<B>96</B>     gr    Chlorphenol, 22     gr     Harnstoff,<B>115</B> Teilen     FormaIdehyd    und  <B>18</B> cm' Schwefelsäure 2% werden mit<B>9.5</B>  Teilen Chlorphenol bei<B>70'</B> so lange gerührt,  bis eine homogene Lösung des Harzes ent  standen ist.

   Man     lässt   <B>150,</B> Teile Monohydrat  zufliessen und rührt     weit-er,    bis eine Probe im  gleichen Raumteil Wasser auch in der Kälte  klar     löslieh    ist. Nach Abstumpfen der über  schüssigen Säure mit Natriumkarbonat     lässt     sich das lösliche Harz durch     Aussalzen    mit       Natrium-chlorid    oder durch     Ein-dampfen    als  schwach gefärbte, amorphe Masse gewinnen;

    ihre Lösungen wirken auf basische Farb  stoffe     sia-rk    fällend, besitzen stark     lpimfäl-          lende    Eigenschaften und färben sich mit       Ferrichlorid        rotstichig    blau.



      Ziisatzpateitit to the main patent no. <B> 158243. </B> Process for the preparation of a highly molecular sulphate. It has been found that new water-soluble condensation products can be achieved if solid, acidic condensed synthetic resins based on formaldelide are treated with phenol, its homologues or substitution products and the resulting homogeneous mass treated with sulphonating agents.



  The present invention relates to a method for the preparation of a high molecular weight sulfonic acid, characterized in that a synthetic resin obtained by condensation of a technical mixture of o- and p-chlorophenol and urea with formaldehyde using acidic catalysts in one Technical mixture of o- and p-chloro-r-phenol dissolves and treated with .sulphonating agents until water-soluble.



  In the form of its alkali salt, the new body is a weakly colored, amorphous mass. In addition to being a tanning agent, the product can also serve as a wool reservation agent in the <B><I>k3</I> </B> semi-wool dyeing process. <I> Example: </I> <B> 8.6 </B> parts of a resin obtained by condensation of <B> 96 </B> gr chlorophenol, 22 gr urea, <B> 115 </B> parts Formaldehyde and <B> 18 </B> cm 'sulfuric acid 2% are stirred with <B> 9.5 </B> parts of chlorophenol at <B> 70' </B> until a homogeneous solution of the resin has formed .

   <B> 150 </B> parts of monohydrate are allowed to flow in and stirring is continued until a sample in the same volume of water is clearly soluble even in the cold. After the excess acid has been blunted with sodium carbonate, the soluble resin can be obtained as a weakly colored, amorphous mass by salting out with sodium chloride or by evaporation;

    Their solutions have a sia-rk precipitating effect on basic dyestuffs, have strong impregnating properties and turn a reddish blue color with ferric chloride.
