Description

  

      Verfahren    mir     Darstelhtng    einer     hochmolekularen        Sulfosäure.       Es wurde gefunden, dass man zu neuen,  wasserlöslichen Kondensationsprodukten ge  langen kann, wenn man feste, sauer     konden-          @ierte    Kunstharze auf     Formaldehydbasis     einer Behandlung 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       hoehmolekula.ren        Sulfosäure,    dadurch ge  kennzeichnet, dass man ein durch     Konden-          sation    von     o-Kresol    und Harnstoff mit Form  aldehyd unter     Mitverwendung    von sauren       Katalysatoren    erhaltenes Kunstharz in Phe  nol löst und bis zur Wasserlöslichkeit mit       sulfonierenden    Mitteln behandelt.  



  Der neue Körper stellt in Form seine       Alkalisalzes    eine schwach gefärbte, amorphe       :Masse    dar. Ausser als Gerbstoff kann das  Produkt als     Wollreservierungsmittel    in der       Halbivollfärberei    dienen.         Beispiel:     Ein Harz, erhalten durch Kondensation  von 82 Teilen     o-Kresol,    32 Teilen Harn  stoff, 112 Teilen Formaldehyd und 21 Teilen  Schwefelsäure 4 % wird mit 125 Teilen Phe  nol bei<B>70'</B> solange gerührt, bis eine homo  gene Lösung des Harzes entstanden ist.

   Man       lä.sst    nun zwischen 45 und 95   130 Teile  konzentrierte Schwefelsäure zufliessen und  rührt weiter, bis eine     Probe    im gleichen  Raumteil Wasser auch in der Kälte klar lös  lich ist. Nach     Abstumpfen    der überschüs  sigen Säure mit Natriumkarbonat lässt sieh  das lösliche Harz durch     Aussalzen    mit Na  triumchloricl oder durch Eindampfen als  schwach gefärbte, amorphe Masse gewinnen:  ihre Lösungen wirken auf basische Farb  stoffe stark fällend, besitzen     stark.    leim  fällende Eigenschaften und färben sich mit       Ferrichlorid        rotstichig    blau.



      Process with presentation of a high molecular weight sulfonic acid. It has been found that new, water-soluble condensation products can be obtained if solid, acid-condensed synthetic resins based on formaldehyde are treated with phenol, its homologues or substitution products and the resulting homogeneous mass is also subjected. treated with sulphonating agents.



  The present invention relates to a method for the preparation of a high-molecular sulfonic acid, characterized in that a synthetic resin obtained by condensation of o-cresol and urea with formaldehyde using acidic catalysts is dissolved in phenol and up to Water solubility treated with sulfonating agents.



  In the form of its alkali salt, the new body represents a weakly colored, amorphous: mass. In addition to being used as a tanning agent, the product can also serve as a wool reservation agent in semi-solid dyeing. Example: A resin obtained by condensing 82 parts of o-cresol, 32 parts of urea, 112 parts of formaldehyde and 21 parts of sulfuric acid 4% is stirred with 125 parts of phenol at 70 'until a homogeneous solution of the resin has arisen.

   Between 45 and 95 130 parts of concentrated sulfuric acid 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 dulled with sodium carbonate, the soluble resin can be obtained as a weakly colored, amorphous mass by salting out with sodium chloride or by evaporation: its solutions have a strong precipitating effect on basic dyes, are strong. glue-precipitating properties and turn a reddish blue color with ferric chloride.
