Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 158243.    Verfahren zur Darstellung einer     hoeltmolekularen        Sulfosäure.       Es wurde gefunden, dass man zu neuen,  wasserlöslichen Kondensationsprodukten ge  langen kann, wenn man feste, sauer kon  densierte Kunstharze auf     riormaldehydbasis     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 Darstellung einer hoch  molekularen     Sulfosäure,    dadurch gekenn  zeichnet, dass man ein durch Kondensation  von Phenol und Harnstoff mit Formaldehyd  unter     Mitverwendung    von sauren Katalysa  toren erhaltenes Kunstharz in einem tech  nischen Gemisch der drei     isomeren        Kresole     löst und bis zur Wasserlöslichkeit mit     sul-          fonierenden    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>  6 7 Teile eines Harzes, erhalten durch Kon  densation von 75 Teilen Phenol, 10 Teilen  Harnstoff, 115 Teilen Formaldehyd und  1 Teil     konz.        .Schwefelsäure,    werden mit  65 Teilen     Rohkresol    bei<B>70'</B> bis 75   so lange  gerührt, bis eine homogene Lösung des Har  zes entstanden ist.

   Man lässt nun zwischen  75   und 100  <B>110</B> Teile Schwefelsäure  66       13e    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  triumkarbonat     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.



  <B> Additional patent </B> to main patent no. 158243. Process for the preparation of a high molecular 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 riormaldehyde to 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 the preparation of a high molecular weight sulfonic acid, characterized in that a synthetic resin obtained by condensation of phenol and urea with formaldehyde using acidic catalysts is dissolved in a technical mixture of the three isomeric cresols and up to treated with sulphonating agents for water solubility.



  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> 6 7 parts of a resin obtained by condensation of 75 parts of phenol, 10 parts of urea, 115 parts of formaldehyde and 1 part of conc. .Sulfuric acid are stirred with 65 parts of raw cresol at <B> 70 '</B> to 75 until a homogeneous solution of the resin has formed.

   Between 75 and 100 parts of sulfuric acid 66 13e 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 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.
