Description

  

  Verfahren zur Darstellung einer hochmolekularen     Sulfosäure.       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     Subatitutionsprodukten    unterwirft  und die entstehende homogene Masse mit     sul-          fonierenden    Mitteln behandelt.  



  Vorliegende     Erfindung    bezieht sich nun  auf ein Verfahren zur     Darstellung        einer     hochmolekularen     Sulfosäure,    dadurch ge  kennzeichnet,     dass    man ein durch Kondensa  tion eines technischen Gemisches von 2',4  und     2,6-Dichlorphenol    und Harnstoff mit  Formaldehyd unter     Mitverwendung    von  sauren Katalysatoren erhaltenes Kunstharz  in einem technischen Gemisch von o- und     p-          Chlorphenol    löst und     bis.    zur Wasserlöslich  keit 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 59     Teilen        Dichlorphenol,    16 Teilen Harn  stoff, 56 Teilen     Formaldehydlösung    und  2 am' Schwefelsäure 40% wird mit 165 Tei  len Chlorphenol bei<B>70'</B> so lange gerührt, bis  eine homogene     Lösung,des    Harzes entstanden  ist.

   Man lässt nun zwischen 65 bis 75   310  Teile     Oleum        12!%    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 starke leimfällende Eigenschaften  und färben sich mit     Ferrichlorid        rotstichig     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 resulting homogeneous mass is treated with sulphonating agents.



  The present invention now relates to a method 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 ', 4 and 2,6-dichlorophenol and urea with formaldehyde using acidic catalysts is added a technical mixture of o- and p-chlorophenol dissolves and up. treated with sulfonating agents for water solubility.



  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 59 parts of dichlorophenol, 16 parts of urea, 56 parts of formaldehyde solution and 2% sulfuric acid is mixed with 165 parts of chlorophenol at <B> 70 '</ B > Stirred until a homogeneous solution of the resin has formed.

   Between 65 to 75,310 parts of 12% oleum 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.
