Description

  

  Verfahren zur Darstellung einer hochmolekularen     Sulfosäure.       Es wurde gefunden,     dass    man zu neuen,       wa,sserlöslichen    Kondensationsprodukten ge  langen kann, wenn man     feste,,sauer    konden  sierte Kunstharze auf     Formaldehydbasis     einer Behandlung mit Phenol, seinen Homo  logen oder     Substitutionsprodukten    unterwirft  und die entstellende homogene Masse mit sul  fonierenden Mitteln behandelt.  



  Vorliegende Erfindung bezieht sieh     nun     auf ein Verfahren zur Darstellung einer  hochmolekularen     Sulfosäure,    dadurch gekenn  zeichnet,     dass    man ein durch Kondensation  von Phenol mit Formaldehyd unter     Mit-          verwendung    von sauren Katalysatoren erhal  tenes Kunstharz in Phenol löst     und    bis zur  Wasserlöslichkeit mit     sulionierenden    Mitteln  behandelt.  



  Der neue Körper stellt in Form seines       Alkalisa,Izes    eine     seliwach    gefärbte,     amorphe     Masse dar. Ausser als Gerbstoff kann das  Produkt als     Wollreservierungsmittel    in der       Halbwolliärberei    dienen.

      <I>Beispiel:</I>    <B>75</B> Teile     Plienol    und 120 Teile     Form-          aldehydlösun        'g        377o    (Gewicht) werden nach  Zusatz von<B>1,5</B> Teilen konzentrierter Schwe  felsäure zunächst 2 Stunden auf<B>55</B>     ',    dann  auf<B>85 '</B> erhitzt, bis die Masse in der Kälte       brüchie,    ist.  



  <B>C</B>  <B>85</B> Teile dieses Harzes werden mit<B>95</B>  Teilen Phenol verschmolzen und bei<B>75 bis</B>  <B>105 '</B> mit<B>95</B> Teilen konzentrierter     Schwefel-          säurt    bis zur     Wasserlöslielikeit    verrührt.  Die überschüssige Schwefelsäure wird nach  irgend einer bekannten Methode entfernt und  mit     Natriumearbonat    das     Natriumsalz    der       Harzsulfosäure    durch     Aussalzen    oder     Ein-          .dampfen    gewonnen. Die neue Verbindung  ist ein bräunlich gefärbtes, etwas     hygros-          ke,pisch,es    Pulver.

   Ihre wässerige Lösung be  sitzt stark     leimfällen-de    Eigenschaften und  färbt sich mit     Ferrichlorid    kräftig     rot-          stichig    blau.



  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 treated with phenol, its homologues or substitution products and the disfiguring homogeneous mass is treated with sulphonating 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 phenol with formaldehyde using acidic catalysts is dissolved in phenol and treated with sulfonating agents until it is water-soluble.



  The new body, in the form of its Alkalisa, Izes, is a self-colored, amorphous mass. In addition to being a tanning agent, the product can also serve as a wool reservation agent in semi-woolen dyeing.

      <I> Example: </I> <B> 75 </B> parts of plienol and 120 parts of formaldehyde solution 377o (weight) are initially added after <B> 1.5 </B> parts of concentrated sulfuric acid Heat for 2 hours at <B> 55 </B> ', then at <B> 85' </B> until the mixture is brittle in the cold.



  <B> C </B> <B> 85 </B> parts of this resin are fused with <B> 95 </B> parts of phenol and <B> 75 to </B> <B> 105 '</ B> stirred with <B> 95 </B> parts of concentrated sulfuric acid until it is water-soluble. The excess sulfuric acid is removed by any known method and the sodium salt of the resin sulfonic acid is obtained with sodium carbonate by salting out or evaporation. The new compound is a brownish, somewhat hygroscopic, pish-like powder.

   Their aqueous solution has strong glue-precipitating properties and turns a strong reddish blue with ferric chloride.
