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 Homo  logen oder     Substitutionsprodukten    unterwirft  und die entstehende homogene Masse mit  sulfonierenden Mitteln behandelt.  



  Vorliegende Erfindung bezieht sich nun  auf ein Verfahren zur Darstellung einer  hochmolekularen     Sulfosäure,    dadurch ge  kennzeichnet, dass man ein durch Konden  sation von     p-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 seines       Alkalisalzes    eine schwach gefärbte, amorphe  Masse dar. Ausser als Gerbstoff kann das  Produkt als     Wollreservierungsmittel    in der       Halbwollfärberei    dienen.    <I>Beispiel:</I>       Ein    Harz, erhalten durch Kondensation  von 61,5 Teilen     p-Kresol,    24 Teilen Harn  stoff, 80 Teilen Formaldehyd und     1-6    Teilen  Schwefelsäure 4 % wird mit     105    Teilen Phe  nol bei<B>70'</B> solange gerührt, bis eine homo  gene Lösung des Harzes entstanden ist.

   Man  lässt nun zwischen 50 bis<B>90'</B> 108 Teile  Schwefelsäure<B>6,6'</B>     B6        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     Aussalzen    mit     Natriumchlorid     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 subjected to a treatment with phenol, its homologues or substitution products and the resulting homogeneous mass is treated with sulfonating agents.



  The present invention now relates to a method for the preparation of a high molecular weight sulfonic acid, characterized in that a synthetic resin obtained by condensation of p-cresol and urea with formaldehyde using acidic catalysts is dissolved in phenol and with sulfonating agents until it is water-soluble Funds 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> A resin obtained by condensation of 61.5 parts of p-cresol, 24 parts of urea, 80 parts of formaldehyde and 1-6 parts of sulfuric acid 4% is mixed with 105 parts of phenol at <B> 70 '</B> stirred until a homogeneous solution of the resin has formed.

   Between 50 to <B> 90 '</B> 108 parts of sulfuric acid <B> 6.6' </B> B6 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 is 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.
