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-          >:ierte    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 Darstellung einer hoch  molekularen     Sulfosäure,    dadurch gekenn  zeichnet, dass man ein durch Kondensation  von Phenol und Harnstoff mit Formaldehyd       iInter        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       Alka.lisalzes    eine schwach gefärbte, amorphe  Masse dar. Ausser als Gerbstoff kann das  Produkt als     Wollreservierungsmittel    in der       Halbwollfärberei    dienen.    <I>Beispiel:</I>  80 Teile eines Harzes, erhalten durch Kon  densation von 100 Teilen Phenol, 20 Teilen  Harnstoff, 1210 Teilen     Formaldehydlösung     38%ig (Gewicht) und 2 bis 5 Teilen Schwe  felsäure 40 %     ig    bei 85   werden mit 100 Tei  len Phenol bei<B>70'</B> so lange gerührt, bis eine'  homogene Lösung des Harzes entstanden ist.

    Man lässt nun zwischen 40' und<B>110'</B>  100 Teile Schwefelsäure von 66       Be    zu  fliessen und rührt weiter, bis eine Probe im  gleichen Raumteil Wasser auch in der Kälte  klar löslich ist. Nach Abstumpfen der über  schüssigen Säure mit Natriumkarbonat lässt  sich das lösliche Harz durch     Aussalzen    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     Ferrichlo-          rid        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, acidic condensation>: ierte synthetic resins based on formaldehyde are treated with phenol. subjecting it to its homologues or substitution products and treating the resulting homogeneous mass with sulfonating 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 phenol and urea with formaldehyde is dissolved in phenol and with sulfonating agents until it is water-soluble treated.



  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> 80 parts of a resin obtained by condensation of 100 parts of phenol, 20 parts of urea, 1210 parts of 38% formaldehyde solution (weight) and 2 to 5 parts of 40% sulfuric acid at 85 are added 100 parts phenol stirred at <B> 70 '</B> until a homogeneous solution of the resin has formed.

    Between 40 'and <B> 110' </B> 100 parts of sulfuric acid of 66 Be are now allowed to flow 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 pale, 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-tinged blue with ferric chloride.
