Description

  

  Verfahren zur     Darstellung    einer hochmolekularen     Sulfosäure.       Es wurde gefunden, dass man zu neuen,  wasserlöslichen Kondensationsprodukten ge  langen kann, wenn man feste, sauer kon  densierte Kunstharze auf     Formaldehydbasis     einer Behandlung mit Phenol, seinen Ho  mologen oder     Substitutionsprodukten    unter  wirft und die entstehende homogene Masse  mit sulfonierenden Mitteln behandelt.  



  Vorliegende Erfindung bezieht sich nun  auf ein Verfahren zur Herstellung einer hoch  molekularen     Sulfosäure,    dadurch gekenn  zeichnet, dass man ein durch Kondensation  von Phenol und     p-Toluolsulfamid    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.         Beispiel:     Ein Harz, erhalten durch Kondensation  von 44 Teilen Phenol, $7,5 Teilen     Toluol-          sulfamid,    90 Teilen Formaldehyd und 10  Teilen Schwefelsäure 4%, wird mit 62 Teilen  Phenol bei 70   so lange gerührt, bis eine  homogene Lösung des Harzes entstanden ist.

    Man lässt nun     zwischen    45   und<B>90'</B>  6,5 Teile Schwefelsäure 66       B6    zufliessen  und rührt weiter, bis eine Probe im glei  chen 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 Farb  stoffe stark fällend, besitzen stark leimfäl  lende Eigenschaften und färben sich mit       Ferrichlorid        rotstichig    blau.



  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, acidic 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 process for the production of a high molecular weight sulfonic acid, characterized in that a synthetic resin obtained by condensation of phenol and p-toluenesulfamide 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. Example: A resin obtained by condensation of 44 parts of phenol, 7.5 parts of toluenesulfamide, 90 parts of formaldehyde and 10 parts of sulfuric acid 4% is stirred with 62 parts of phenol at 70 until a homogeneous solution of the resin has formed .

    Between 45 and 90 ”6.5 parts of sulfuric acid 66 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 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 blue color with ferric chloride.
