Description

  

      Zusatzpatent    zum Hauptpatent     Nr.    158248.         Verfahren    zur Darstellung einer     hochmolekularen        Sultosäure.       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     Ilo-          rnologen    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     Thioharnstoff    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 sehwach gefärbte, amorphe  Masse dar. Ausser als Gerbstoff kann das  Produkt als     Wollreservierungsmittel    in der       Halbwollfärberei    dienen.         Beispiel:          62?    Teile eines Harzes, erhalten durch  Kondensation von 38 Teilen Phenol, 18 Tei  len     Thioharnstoff,    65 Teilen     Förmaldehyd     und ? Teilen Schwefelsäure     .10%,    werden  mit 55 Teilen Phenol bei 65<B>'</B>bis 70   so lange  gerührt, bis eine homogene Lösung des Har  zes entstanden ist.

   Man lässt nun zwischen  55   und<B>100'</B> 90 Teile Schwefelsäure  66       1e    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.



      Additional patent to main patent No. 158248. Process for the preparation of a high molecular sulto acid. It has been found that new, water-soluble condensation products can be obtained if solid, acid-condensed synthetic resins based on formaldehyde are treated with phenol, its ilonologues or substitution products and the resulting homogeneous mass is treated with sulfonating agents.



  The present invention relates to a process for preparing a high molecular weight sulfonic acid, characterized in that a synthetic resin obtained by condensation of phenol and thiourea with formaldehyde using acidic 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 very 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: 62? Parts of a resin obtained by condensation of 38 parts of phenol, 18 parts of thiourea, 65 parts of formaldehyde and? Parts of sulfuric acid .10% are stirred with 55 parts of phenol at 65 to 70 until a homogeneous solution of the resin has formed.

   Between 55 and <B> 100 '</B> 90 parts of sulfuric acid 66 1e 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.
