Description

  

  Verfahren zur     Darstellunb    einer hochmolekularen     Sulfosäure.       Es wurde gefunden, dass man zu neuen,  wasserlöslichen Kondensationsprodukten ge  langen kann, wenn man feste, sauer konden  sierte Kunstharze auf     Formaldehydbasis     einer Behandlung mit Phenol, seinen Homo  logen oder     Substitutionsprodukten    unter  wirft und die entstehende homogene Masse  mit sulfonierenden Mitteln behandelt.  



  Vorliegende Erfindung bezieht sich nun  auf ein Verfahren zur Darstellung einer       bochmolekularen        Sulfosäure,    dadurch ge  kennzeichnet, dass man ein durch Kondensa  tion von Phenol und Harnstoff mit Formal  dehyd unter     Mitverwendung    von sauren  Katalysatoren erhaltenes Kunstharz in einem       i,eehnischen    Gemisch von o- und     p-Chlor-          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 (las  Produkt als     Wollreservierungsmittel    in der       Halbwollfärberei    dienen.    <I>Beispiel:</I>  67 Teile eines Harzes erhalten durch  Kondensation von 75 Teilen Phenol, 40 Tei  len Harnstoff, 120 Teilen Formaldehyd und  25 Teilen Schwefelsäure 4% werden mit 78  Teilen Chlorphenol bei<B>70'</B> solange gerührt, bis  eine homogene Lösung des Harzes     enIstan-          den    ist.

   Man lässt nun zwischen 40- und 110    95 Teile Schwefelsäure von 6,6       Be    zufliessen  und rührt weiter, bis eine Probe im gleichen  Raumteil Wasser auch in der Kälte klar lös  lich ist. Nach Abstumpfen der überschüssigen  Säure mit Natriumkarbonat lässt sich das  lösliche Harz durch     Aussalzen    mit Natrium  chlorid oder durch Eindampfen als schwach  gefärbte, amorphe Masse gewinnen; ihre  Lösungen wirken auf basische Farbstoffe  stark fällend, besitzen stark leimfällende  Eigenschaften und färben sich mit     Ferri-          chlorid        rotstichig    blau.



  Process for the preparation of a high molecular weight sulfonic acid. It has been found that you can ge to new, water-soluble condensation products if you throw solid, acid-condensed synthetic resins based on formaldehyde under a treatment with phenol, its homologues or substitution products and treat the resulting homogeneous mass with sulfonating agents.



  The present invention relates to a method for the preparation of a bochmolecular sulfonic acid, characterized in that a synthetic resin obtained by condensation of phenol and urea with formaldehyde using acidic catalysts is obtained in an i, eehnischen mixture of o- and p- Chlorophenol dissolves and treated with sulfonating agents until it is water-soluble.



  In the form of its alkali salt, the new body is a weakly colored, amorphous mass. In addition to being used as a tanning agent, (the product can serve as a wool reservation agent in semi-wool dyeing. <I> Example: </I> 67 parts of a resin obtained by condensing 75 parts of phenol 40 parts of urea, 120 parts of formaldehyde and 25 parts of sulfuric acid 4% are stirred with 78 parts of chlorophenol at 70 'until a homogeneous solution of the resin is obtained.

   Between 40 and 110 95 parts of sulfuric acid of 6.6 Be are now allowed to flow in and stirring is continued until a sample in the same volume of water is clearly soluble 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 strong precipitating effect on basic dyes, have strong glue-precipitating properties and turn a reddish blue color with ferric chloride.
