      Z-tisatzpatent    zum Hauptpatent     Nr.   <B>158243.</B>    Verfahren zur Darstellung einer     hoehinolokularen        Salfosilure.       Es wurde gefunden,     dass    man zu neuen,  wasserlöslichen     Kondensationsprodu   <B>-</B>     kten        _ge_-          langen    kann, wenn man feste, sauer konden  sierte Kunstharze auf     Formaldehydbasis     einer Behandlung mit Phenol, seinen Homo  logen oder     Substitutionsprodukten    unterwirft  und die entstehende homogene Masse mit       sulionierenden    Mitteln behandelt.  



  Vorliegende Erfindung bezieht sich nun  auf ein Verfahren zur Darstellung einer  hochmolekularen     Sulfosäure,    dadurch ge  kennzeichnet,     dass    man ein durch Konden  sation eines technischen Gemisches von     2,1-          und        2,6-Dichlorphenol    und Harnstoff mit  Formaldehyd unter     Mitverwendung    von sau  ren Katalysatoren erhaltenes Kunstharz in  einem technischen Gemisch von o- und       p-Chlorphenol    und von 2,4- und     2,6-Dichlor-          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     Wallreservierungsmittel    in der       Ila.Ibwollfärberei    dienen.  



  <I>Beispiel:</I>  <B>55</B> Teile eines Harzes, erhalten durch  Kondensation von<B>105</B> Teilen     Dichlorphenol,     <B>26</B> Teilen     Harnstoff,   <B>100</B> Teilen     Formalde-          hydlösung    und<B>15</B> cm' Schwefelsäure 4<B>%</B>  werden mit 4,5 Teilen Chlorphenol und<B>55</B>  Teilen     Dichlorphenol.    bei<B>85 '</B> solange ge  rührt, bis eine homogene Lösung des Harzes  entstanden ist. Man     lässt    nun zwischen<B>60</B>  und<B>95 ' 185</B> Teile     Oleum        ll%    zufliessen  und rührt weiter, bis eine Probe im     gleicheu     Raumteil Wasser auch in der Kälte klar  löslich ist.

   Nach Abstumpfen der überschüs  sigen Säure mit Natriumkarbonat     lässt        sie71i     das lösliche Harz durch     Aussalzen    mit     Na-          triunichlorid    oder durch Eindampfen als  schwach gefärbte, amorphe Masse gewinnen,  ihre Lösungen wirken auf     basi#sclie    Farb  stoffe stark     fäl   <B>-</B>     lend,    besitzen stark leim  fällende Eigenschaften und färben sich mit       Ferrichlorid        rotstichig    blau.



      Additional patent for main patent no. <B> 158243. </B> Process for the representation of a high ocular salfosilure. It has been found that new, water-soluble condensation products can be achieved by subjecting solid, acid-condensed synthetic resins based on formaldehyde to a treatment with phenol, its homologues or substitution products and the resulting homogeneous Mass treated 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 a technical mixture of 2,1- and 2,6-dichlorophenol and urea with formaldehyde using acidic catalysts is used dissolves in a technical mixture of o- and p-chlorophenol and of 2,4- and 2,6-dichlorophenol and up to water solubility; treated with sulfonating agents.



  The new body, in the form of its alkali salt, is a weakly colored, amorphous mass. In addition to being a tanning agent, the product can also serve as a wall reserve in Ila.Ibwollfärberei.



  <I> Example: </I> <B> 55 </B> parts of a resin, obtained by condensation of <B> 105 </B> parts of dichlorophenol, <B> 26 </B> parts of urea, <B> 100 parts formaldehyde solution and 15 cm sulfuric acid 4% are mixed with 4.5 parts chlorophenol and 55 parts dichlorophenol. Stirred at <B> 85 '</B> until a homogeneous solution of the resin has formed. Between <B> 60 </B> and <B> 95 '185 </B> parts of oleum II% 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, she lets the soluble resin be obtained as a weakly colored, amorphous mass by salting out with sodium chloride or by evaporation; her solutions have a strong precipitating effect on basic dyes , have strong glue-precipitating properties and turn a reddish blue color with ferric chloride.
