Description

  

  verfahren zur Darstellung einer     hoehmolekular    en     Sulfosäur    e.    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    unterwirft  und die entstehende homogene Masse mit sul  fonierenden Mitteln behandelt.  



  Vorliegende Erfindung bezieht sich nun  auf ein Verfahren zur     Darstellung    einer  hochmolekularen     Sulfosä:ure,    dadurch ge  kennzeichnet, dass man ein durch Konden  sation von     Chlor-m-kresol    (2,5) und Harn  stoff mit Formaldehyd unter     Mitverwen-          dung    von sauren Katalysatoren erhaltenes  Kunstharz in Phenol löst und bis zur Was  serlöslichkeit mit     sulfonierenden    Mitteln be  handelt.  



  Der neue     Körper    stellt in Form seines       Alkalisalzes    eine schwach     gefärbte,    amorphe  Masse dar. Ausser als Gerbstoff kann das  Produkt als     Wollreservierungsmittel    in der       T4alhwollfärberei    dienen.

           Beispiel:     92 Teile eines Harzes erhalten durch  Kondensation von     10$,5    Teilen     Chlor-m-kre-          sol,    26,5 Teilen Harnstoff, 118 Teilen  88%iger     Formaldehydlösung    und 40 cm'  Schwefelsäure     1;5%ig    werden mit 110 Tei  len Phenol bei 70   so lange gerührt, bis eine  homogene Lösung des Harzes entstanden ist.  Man lässt nun zwischen 50 und 95   110 Teile  Schwefelsäure 66       BA    zufliessen und rührt  weiter, bis eine Probe im gleichen     Raumteil     Wasser auch in der Kälte klar löslich ist.

    Nach Abstumpfen der überschüssigen Säure  mit     Natriumkarbonat    lässt sich das lösliche  Harz durch     Aussa.lzen    mit     Natriumchlorid     oder durch Eindampfen als schwach gefärbte,       amorphe    Masse gewinnen; ihre Lösungen  wirken auf     basische    Farbstoffe stark fällend.



  process for the preparation of a high molecular weight sulfonic acid e. 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 treated with sulphonating agents.



  The present invention relates to a process for the preparation of a high molecular weight sulfonic acid, characterized in that one obtained by condensation of chlorine-m-cresol (2.5) and urea with formaldehyde using acidic catalysts Synthetic resin dissolves in phenol and treats with sulfonating agents until water is soluble.



  In the form of its alkali salt, the new body represents a weakly colored, amorphous mass. In addition to being a tanning agent, the product can also serve as a wool reservation agent in T4alh wool dyeing.

           Example: 92 parts of a resin obtained by condensation of 10 $, 5 parts of chlorine-m-cre-sol, 26.5 parts of urea, 118 parts of 88% formaldehyde solution and 40 cm of sulfuric acid 1.5% with 110 parts Phenol stirred at 70 until a homogeneous solution of the resin has formed. Between 50 and 95 110 parts of sulfuric acid 66 BA are now 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 strong precipitating effect on basic dyes.
