Description

  

      Zusatzpatent    zum Hauptpatent Nr. 158243.    Verfahren zur Darstellung einer     hochmolekularen        Sulfosüure.       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     sulfo-          nierenden-Mitteln    behandelt.  



  Vorliegende Erfindung bezieht sich nun  auf ein Verfahren zur Herstellung einer hoch  molekularen     Sulfosäure,    dadurch gekenn  zeichnet, dass man ein durch Kondensation  eines technischen Gemisches von o- und     p-          Chlorphenol    und Harnstoff mit Formaldehyd  unter     Mitverwendung    von sauren Katalysa  toren erhaltenes Kunstharz in Phenol löst  und bis zur Wasserlöslichkeit mit     sulfonie-          renden    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>  Man kondensiert 96 Teile Chlorphenol  (zum Beispiel erhalten durch Einwirkenlas  sen molekularer Mengen     Sulfurylchlorid    auf  Phenol) und 21 Teile Harnstoff mit 115 Tei  len Formaldehyd und 25 Teilen Schwefel  säure     47o.    7 5 Teile dieses Harzes verrührt  man mit 95 Teilen Phenol bei<B>60',</B> bis die  Masse homogen erscheint, und     sulfiert    dann  mit 100 Teilen Monohydrat bei<B>70'</B> bis<B>80',</B>  bis der gewünschte Löslichkeitsgrad erreicht  ist.

   Nach Abstumpfen der überschüssigen  Säure mit Natriumkarbonat lässt sich das lös  liche Harz durch     Aussalzen    mit     Natriumchlo-          rid    oder durch Eindampfen als schwach ge  färbte, amorphe Masse gewinnen; ihre Lö  sungen wirken auf basische Farbstoffe stark  fällend, besitzen stark leimfällende Eigen  schaften 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 sulfonating agents.



  The present invention relates to a process for the production 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 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> 96 parts of chlorophenol (obtained, for example, by allowing molecular amounts of sulfuryl chloride to act on phenol) and 21 parts of urea with 115 parts of formaldehyde and 25 parts of sulfuric acid 47o are condensed. 75 parts of this resin are stirred with 95 parts of phenol at <B> 60 ', </B> until the mass appears homogeneous, and then sulfated with 100 parts of monohydrate at <B> 70' </B> to <B> 80 ', </B> until the desired degree of solubility is achieved.

   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.
