Description
Zusatzpatent zum Hauptpatent Nr. 158243. Verfahren zur Darstellung einer hochmolekularen Nulfosäure. 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 Darstellung einer hochmolekularen Sulfosäure, dadurch gekenn zeichnet, dass man ein durch Kondensation eines technischen Gemisches isonrerer Xylen- ole vom Sdp. 209/220 0 C und Harnstoff mit Formaldehyd unter Mitverwendung von sauren Katalysatoren erhaltenes Kunstharz in Phe nol 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 Halbwol)färberei dienen.
<I>Beispiel:</I> 75 Teile eines Harzes erhalten durch Kon densation von 120 Teilen Xylenol, 32 Teilen Harnstoff, 125 Teilen Formaldehydlösung 38 % ig und 25 Teilen Schwefelsäure 4'/o bei<B>780</B> werden mit 100 Teilen Phenol bei <B>700</B> solänge gerührt, bis eine homogene Lösung des Harzes entstanden ist.
Man lässt nun zwischen 40 0 und 110 0 125 Teile Schwefel säure von 66 0 B6 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 triunicarbonat 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 stark leimfällende Eigenschaften 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 subjected to a treatment 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 preparation of a high molecular weight sulfonic acid, characterized in that a synthetic resin obtained by condensation of a technical mixture of isonereric xylenes with bp. 209/220 0 C and urea with formaldehyde is incorporated into Phenol dissolves 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> 75 parts of a resin obtained by condensation of 120 parts of xylenol, 32 parts of urea, 125 parts of 38% formaldehyde solution and 25 parts of sulfuric acid 4% at 780 stirred with 100 parts of phenol at <B> 700 </B> until a homogeneous solution of the resin has formed.
It is now allowed to flow in between 40 0 and 110 0 125 parts of sulfuric acid of 66 0 B6 and stirring is continued until a sample in the same volume of water is clearly soluble even in the cold. After blunting the excess acid with sodium triunicarbonate, the soluble resin can be pale colored by salting out with sodium chloride or by evaporation; gain amorphous mass; Their solutions have a strong precipitating effect on basic dyes, have strong glue-precipitating properties and turn a reddish blue color with ferric chloride.
