Description
Zusatzpatent zum Hauptpatent Nr.<B>158243.</B> 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 F'ormaldehydbasis einer Behandlung mit Phenol, seinen Homologen oder Substitutionsprodukten unterwirft und die entstehende homogene Masse mit sulfo- nierenden Mitteln behandelt.
Vorliegende Erfindung bezieht sich nun auf ein Verfahren zur Darstellung einer hoch molekularen Sulfosäure, dadurch gekenn zeichnet, dass man ein durch Kondensation eines technischen Gemisches von 2',4- und 2,6-Dichlorphenol und Harnstoff mit Form- aldeyd unter Mitverwendung von sauren Ka talysatoren erhaltenes Kunstharz in Phenol löst und bis zur Wasserlöslichkeit mit sulfo- nierenden 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: 910 Teile eines Harzes erhalten durch Kondensation von 1;2i2 Teilen Dichlorphenol mit 35 Teilen Harnstoff, 110 Teilen 38%iger Formaldehydlösung und 20 Teilen Salzsäure -? % werden mit 95 Teilen Phenol bei 65 so lange gerührt, bis eine homogene Lösung des Harzes entstanden ist.
Man läss't nun zwi schen 40' und<B>110'</B> 95 Teile Schwefelsäure (Monohydrat) zufliessen und rührt weiter, bis eine Probe im gleichen Raumteil Wasser auch in .der Kälte klar löslich ist. Nach Abstumpfen der' überschüssigen Säure mit Natriumkarbonat lässt sich das lösliche Harz durch Aussalzen mit Natriumchlorid oder durch Eindampfen als schwach gefärbte, amorphe Masse gewinnen; ihre Lösungen wir ken auf basische Farbstoffe stark fällend, be sitzen stark leimfällende Eigenschaften und färben sich mit Ferrichlorid rotstichig blau.
Additional patent to main patent no. <B> 158243. </B> Process for the preparation of a high molecular weight sulfonic acid. It has been found that new, water-soluble condensation products can be obtained by subjecting solid, acid-condensed synthetic resins based on formaldehyde to a treatment with phenol, its homologues or substitution products and treating the resulting homogeneous mass with sulfonating agents.
The present invention now relates to a method for the preparation of a high molecular weight sulfonic acid, characterized in that one by condensation of a technical mixture of 2 ', 4- and 2,6-dichlorophenol and urea with formaldehyde with the use of acidic Ka The synthetic resin obtained from the catalysts 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. . Example: 910 parts of a resin obtained by condensation of 1.2 parts of dichlorophenol with 35 parts of urea, 110 parts of 38% formaldehyde solution and 20 parts of hydrochloric acid -? % are stirred with 95 parts of phenol at 65 until a homogeneous solution of the resin has formed.
Between 40 'and <B> 110' </B> 95 parts of sulfuric acid (monohydrate) are now allowed to flow in and stirring is continued until a sample in the same part of the volume of water is clearly soluble in the cold. After the excess acid has been blunted with sodium carbonate, the soluble resin can be obtained as a pale, 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.
