Description
Zusatzpatent zum Hauptpatent Nr. 158243. Verfahren zur Darstellung einer hochmolekularen Sulfosüure. 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 Homologen oder Substitutionsprodukten unterwirft und die entstehende homogene Masse mit sulfo- nierenden-Mitteln behandelt.
Vorliegende Erfindung bezieht sich nun auf ein Verfahren zur Herstellung einer hoch molekularen Sulfosäure, dadurch gekenn zeichnet, dass man ein durch Kondensation eines technischen Gemisches von o- und p- Chlorphenol und Harnstoff mit Formaldehyd unter Mitverwendung von sauren Katalysa toren erhaltenes Kunstharz in Phenol löst und bis zur Wasserlöslichkeit mit sulfonie- renden 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> Man kondensiert 96 Teile Chlorphenol (zum Beispiel erhalten durch Einwirkenlas sen molekularer Mengen Sulfurylchlorid auf Phenol) und 21 Teile Harnstoff mit 115 Tei len Formaldehyd und 25 Teilen Schwefel säure 47o. 7 5 Teile dieses Harzes verrührt man mit 95 Teilen Phenol bei<B>60',</B> bis die Masse homogen erscheint, und sulfiert dann mit 100 Teilen Monohydrat bei<B>70'</B> bis<B>80',</B> bis der gewünschte Löslichkeitsgrad erreicht ist.
Nach Abstumpfen der überschüssigen Säure mit Natriumkarbonat lässt sich das lös liche Harz durch Aussalzen mit Natriumchlo- rid oder durch Eindampfen als schwach ge färbte, amorphe Masse gewinnen; ihre Lö sungen wirken auf basische Farbstoffe stark fällend, besitzen stark leimfällende Eigen schaften und färben sich mit Ferrichlorid rotstichig blau.
Additional patent to main patent No. 158243. 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 sulfonating agents.
The present invention relates to a process for the production of a high molecular weight sulfonic acid, characterized in that a synthetic resin obtained by condensation of a technical mixture of o- and p-chlorophenol and urea with formaldehyde using acidic catalysts is dissolved in phenol and Treated with sulfonating agents until they are 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> 96 parts of chlorophenol (obtained, for example, by allowing molecular amounts of sulfuryl chloride to act on phenol) and 21 parts of urea with 115 parts of formaldehyde and 25 parts of sulfuric acid 47o are condensed. 75 parts of this resin are stirred with 95 parts of phenol at <B> 60 ', </B> until the mass appears homogeneous, and then sulfated with 100 parts of monohydrate at <B> 70' </B> to <B> 80 ', </B> until the desired degree of solubility is achieved.
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.
