Description

  

      Zusatzpatent    zum Hauptpatent Nr. 158243.    Verfahren zur Darstellung 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 Homologen  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 gekenn  zeichnet, dass man ein durch Kondensation       eines    technischen Gemisches -der drei     iso-          rneren        Kresole    und Harnstoff mit Formal  dehyd unter     Mitverwendung    von sauren Ka  talysatoren erhaltenes Kunstharz in Phenol  löst und bis zur Wasserlöslichkeit mit     sulfo-          nierenden    Mitteln behandelt.  



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

      <I>Beispiel:</I>  75 Teile eines Harzes erhalten durch  Kondensation von 85 Teilen     Rohkresol    mit  24 Teilen     Harnstoff,    125 Teilen Formaldehyd       und        28        Teilen        Schwefelsäure        4%        bei        850     werden mit 98 Teilen Phenol bei 70 0 solange  gerührt, bis eine homogene Lösung des  Harzes entstanden ist. Man lässt nun zwi  schen<B>65'</B> und 100 0 105 Teile Schwefel  säure konzentriert zufliessen und rührt weiter,  bis eine Probe im gleichen Raumteil Wasser  auch in der Kälte klar löslich ist.

   Nach  Abstumpfen der überschüssigen Säure mit       Natriumcarbonat    lässt sich das lösliche Harz  durch Aussahen mit     Natriumchlorid    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     Ferrichlorid        rotstichig    blau.



      Additional patent to main patent No. 158243. Process for the preparation 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 treated with sulphonating agents.



  The present invention relates to a process for the preparation of a high molecular weight sulfonic acid, characterized in that a synthetic resin obtained by condensation of a technical mixture of the three isomeric cresols and urea with formaldehyde using acidic catalysts is dissolved in phenol and Treated with sulfonating agents until they are water-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 semi-wool dyeing.

      <I> Example: </I> 75 parts of a resin obtained by condensing 85 parts of crude cresol with 24 parts of urea, 125 parts of formaldehyde and 28 parts of sulfuric acid 4% at 850 are stirred with 98 parts of phenol at 70 ° until homogeneous Solution of the resin has arisen. It is now allowed to flow in between 65 and 100 105 parts of concentrated sulfuric acid 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 pale, amorphous mass by peeling 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.
