Description

  

      7nsatzpatent    zum Hauptpatent Nr. 158243.    Verfahren     zur    Darstellung einer hochmolekularen     Sulfosäur    e.    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 Homo  logen oder     Substitutionsprodukten    unter  wirft und die entstehende homogene Masse  mit     sulfonierenden    Mitteln behandelt.  



  Vorliegende Erfindung bezieht sich nun  auf ein Verfahren zur Darstellung einer  hochmolekularen     Sulfosäure,    dadurch ge  kennzeichnet, dass man ein durch Kondensa  tion von Anilin, Harnstoff und Formaldehyd  unter     Mitverwendung    von sauren Katalysa  toren erhaltenes Kunstharz in Phenol löst  und bis zur Wasserlöslichkeit mit     sulfonieren-          den    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:     75 Teile Anilin und 32,5 Teile Harnstoff  werden mit wenig Wasser angerührt und  5     ein'    Salzsäure<B>W</B>% dazu gegeben. Nach Zu  satz von<B>11,0</B> Teilen Formaldehyd erwärmt  man das Gemisch auf 90  , bis sich das  Kondensationsprodukt als zähe Masse vom  Wasser abgetrennt hat. Zur     Sulfonierung     trägt man in 120 Teile Phenol ein und be  handelt mit<B>170</B> Teilen     konzentrierter    Schwe  felsäure.

   Die     Weiterverarbeitung        erfolgt    in  der im 1. Zusatzpatent angegebenen Weise,  wobei das     Natriumsalz    als     blassgelbes    Pulver  erhalten wird. Mit Eisenchlorid entsteht eine  braunviolette Fällung. Die wässerige Lösung  besitzt stark leimfällende Eigenschaften und  färbt sich mit     Ferrichlorid        braunviolett.  



      7nsatzpatent for main patent no. 158243. 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, acid-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 preparation of a high molecular weight sulfonic acid, characterized in that a synthetic resin obtained by condensation of aniline, urea and formaldehyde using acidic catalysts is dissolved in phenol and with sulfonating agents until it is water-soluble 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: 75 parts of aniline and 32.5 parts of urea are mixed with a little water and 5% hydrochloric acid is added. After adding 11.0 parts of formaldehyde, the mixture is heated to 90 ° until the condensation product has separated off from the water as a viscous mass. For the sulfonation, phenol is added to 120 parts and treated with <B> 170 </B> parts of concentrated sulfuric acid.

   The further processing takes place in the manner indicated in the 1st additional patent, the sodium salt being obtained as a pale yellow powder. With ferric chloride, a brown-violet precipitate is formed. The aqueous solution has strong glue-precipitating properties and turns brown-violet in color with ferric chloride.
