Description

  

      Zusatzpatent    zum Hauptpatent Nr.<B>158243.</B>    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     F'ormaldehydbasis    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  eines technischen Gemisches von 2',4- und       2,6-Dichlorphenol    und Harnstoff mit     Form-          aldeyd    unter     Mitverwendung    von sauren Ka  talysatoren erhaltenes Kunstharz in Phenol  löst und bis zur Wasserlöslichkeit mit     sulfo-          nierenden    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:     910 Teile eines Harzes erhalten durch  Kondensation von     1;2i2    Teilen     Dichlorphenol     mit 35 Teilen Harnstoff, 110 Teilen     38%iger          Formaldehydlösung    und 20 Teilen Salzsäure       -?        %    werden mit 95 Teilen Phenol bei 65  so lange gerührt, bis eine homogene Lösung  des Harzes entstanden ist.

   Man     läss't    nun zwi  schen 40' und<B>110'</B> 95 Teile Schwefelsäure  (Monohydrat) 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 gefärbte,  amorphe Masse gewinnen; ihre Lösungen wir  ken auf basische Farbstoffe stark fällend, be  sitzen stark leimfällende Eigenschaften und  färben sich mit     Ferrichlorid        rotstichig    blau.



      Additional patent to main patent no. <B> 158243. </B> Process for the preparation of a high molecular weight sulfonic acid. It has been found that new, water-soluble condensation products can be obtained by subjecting solid, acid-condensed synthetic resins based on formaldehyde to a treatment with phenol, its homologues or substitution products and treating the resulting homogeneous mass with sulfonating agents.



  The present invention now relates to a method for the preparation of a high molecular weight sulfonic acid, characterized in that one by condensation of a technical mixture of 2 ', 4- and 2,6-dichlorophenol and urea with formaldehyde with the use of acidic Ka The synthetic resin obtained from the catalysts is dissolved in phenol 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. . Example: 910 parts of a resin obtained by condensation of 1.2 parts of dichlorophenol with 35 parts of urea, 110 parts of 38% formaldehyde solution and 20 parts of hydrochloric acid -? % are stirred with 95 parts of phenol at 65 until a homogeneous solution of the resin has formed.

   Between 40 'and <B> 110' </B> 95 parts of sulfuric acid (monohydrate) are now allowed to flow in and stirring is continued until a sample in the same part of the volume of water is clearly soluble 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.
