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    unter  wirft 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     m-Kresol    und Harnstoff mit  Formaldehyd unter     Mitverwendung    von sau  ren Katalysatoren erhaltenes Kunstharz in  Phenol 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.         Beispiel:     Ein Harz, erhalten durch Kondensation  von 72 Teilen     m-Kresol,    32 Teilen Harn  stoff, 98 Teilen Formaldehyd und 2 Teilen  Schwefelsäure<B>50%</B> wird mit 115 Teilen  Phenol bei<B>70'</B> solange gerührt, bis eine  homogene Lösung des Harzes entstanden ist.

    Man lässt nun zwischen 55 und 95   120 Teile       Schwefelsäure    6,6       B6    zufliessen und rührt  weiter, bis eine Probe im gleichen Raumteil  Wasser auch in der Kälte klär löslich ist.  Nach Abstumpfen der überschüssigen Säure  mit Natriumkarbonat lässt sich das lösliche  Harz durch     Aussalzen    mit     Natriumehlorid     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 you can ge to new, water-soluble condensation products if you throw solid, acid-condensed synthetic resins based on formaldehyde under a treatment with phenol, its homologues or substitution products and treat the resulting homogeneous mass with sulfonating agents.



  The present invention relates to a method for preparing a high molecular weight sulfonic acid, characterized in that a synthetic resin obtained by condensation of m-cresol and urea with formaldehyde using acidic catalysts 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. Example: A resin obtained by condensation of 72 parts of m-cresol, 32 parts of urea, 98 parts of formaldehyde and 2 parts of sulfuric acid <B> 50% </B> is mixed with 115 parts of phenol at <B> 70 '</ B > Stirred until a homogeneous solution of the resin is obtained.

    Between 55 and 95 120 parts of sulfuric acid 6.6 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 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.
