Description

  

  Zusatzpatent zum Hauptpatent     Nr.    158243-    Verfahren zur Darstellung einer hochmolekularen     Sulfosäure.       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 Ho  mologen oder     Substitutionsprodukten    unter  wirft und die entstehende homogene Masse  mit     sulionierenden    Mitteln behandelt.  



  Vorliegende Erfindung bezieht sieh nun  auf ein Verfahren zur Darstellung einer hoch  molekularen     Sulfosäure,    dadurch gekenn  zeichnet,     dass    man ein durch Kondensation  von Phenol und     Biuret    mit Formaldehyd un  ter     Mitverwendung        Yön    sauren Katalysatoren  erhaltenes Kunstharz in Phenol löst und bis  zur Wasserlöslichkeit mit sulfonierenden  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>  Ein Harz, erhalten durch Kondensation  von<B>72</B> Teilen Phenol,<B>63</B> Teilen     Biuret,     <B>119,</B> Teilen     Formaldehydlösung    und<B>18</B> Tei  len Schwefelsäure<B>5%,</B> wird mit 120 Teilen  Phenol bei<B>65 '</B> so lange gerührt, bis eine  homogene Lösung des Harzes entstanden ist.

    Man     lässt    nun zwischen     55   <B>'</B> und     10-0'     <B>90</B> Teile Schwefelsäure<B>66 '</B> B6 zufliessen  und rührt weiter, bis eine Probe im gleichen  Raumteil Wasser auch in der Kälte klar lös  lich ist.

   Nach Abstumpfen der überschüs  sigen Säure mit Natriumkarbonat     lässt    sich  das lösliche Harz durch     Aussalzen    mit     Na-          triumehlorid    oder durch Eindampfen als  schwach gefärbte,     amorplie    Masse gewinnen;  ihre Lösungen wirken auf basische Farb  stoffe stark fällend, besitzen stark,     leimfällende     Eigenschaften und färben sich mit     Ferri-          chlorid        rotstichig    blau.



  Additional patent to the 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, acidic condensed synthetic resins based on formaldehyde under a treatment with phenol, its homologues or substitution products and treat the resulting homogeneous mass with sulphonating agents.



  The present invention now 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 and biuret with formaldehyde 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. <I> Example: </I> A resin obtained by condensation of <B> 72 </B> parts of phenol, <B> 63 </B> parts of biuret, <B> 119 </B> parts of formaldehyde solution and <B> 18 </B> parts of sulfuric acid <B> 5% </B> is stirred with 120 parts of phenol at <B> 65 '</B> until a homogeneous solution of the resin has formed.

    You now allow between 55 <B> '</B> and 10-0' <B> 90 </B> parts of sulfuric acid <B> 66 '</B> B6 to flow in and continue stirring until a sample is 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.
