Description

  

      Zusatzpatent    zum Hauptpatent     Nr.    158243.    Verfahren zur Darstellung einer hochmolekularen     Nulfosäure.       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 Darstellung einer  hochmolekularen     Sulfosäure,    dadurch gekenn  zeichnet, dass man ein durch Kondensation  eines technischen Gemisches     isonrerer        Xylen-          ole    vom     Sdp.    209/220 0 C und     Harnstoff    mit  Formaldehyd 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       Halbwol)färberei    dienen.

      <I>Beispiel:</I>  75 Teile eines Harzes erhalten durch Kon  densation von 120 Teilen     Xylenol,    32 Teilen       Harnstoff,    125 Teilen     Formaldehydlösung          38        %        ig        und        25        Teilen        Schwefelsäure        4'/o     bei<B>780</B> werden mit 100 Teilen Phenol bei  <B>700</B>     solänge    gerührt, bis eine homogene  Lösung des Harzes entstanden ist.

   Man lässt  nun zwischen 40 0 und 110 0 125 Teile Schwefel  säure von 66 0     B6    zufliessen und rührt weiter,  bis eine Probe im gleichen Raumteil Wasser  auch in der Kälte klar löslich ist. Nach Ab  stumpfen der überschüssigen Säure mit Na  triunicarbonat 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     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 relates to a process for the preparation of a high molecular weight sulfonic acid, characterized in that a synthetic resin obtained by condensation of a technical mixture of isonereric xylenes with bp. 209/220 0 C and urea with formaldehyde is incorporated into Phenol dissolves and treated with sulfonating agents until it is 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> 75 parts of a resin obtained by condensation of 120 parts of xylenol, 32 parts of urea, 125 parts of 38% formaldehyde solution and 25 parts of sulfuric acid 4% at 780 stirred with 100 parts of phenol at <B> 700 </B> until a homogeneous solution of the resin has formed.

   It is now allowed to flow in between 40 0 and 110 0 125 parts of sulfuric acid of 66 0 B6 and stirring is continued until a sample in the same volume of water is clearly soluble even in the cold. After blunting the excess acid with sodium triunicarbonate, the soluble resin can be pale colored by salting out with sodium chloride or by evaporation; gain amorphous mass; Their solutions have a strong precipitating effect on basic dyes, have strong glue-precipitating properties and turn a reddish blue color with ferric chloride.
