Description
Zusatzpatent zum Hauptpatent Nr. 160439. Verfahren zur HersteHung eines neuen als Reservierungsmittel verwendbaren Kondensationsproduktes. Es wurde gefunden, dass man ein neues Kondensationsprodukt erhält, wen.n man 2 Mol Benzoiii und<B>1</B> Mol 2-Oxynaphthalin-3,6-di- sulfonsäure kondensiert.
Das neue Produkt bildet ein helles Pul ver, das sich in Wasser leicht löst. Es ist durch seine Affinität zur tierischen Faser aus gezeichnet und soll zum Reservieren der Wolle gegenüber Farbstoffen der verschiedensten Klassen verwendet werden.
<I>Beispiel:</I> 40 Teile technisches 2<B>-</B> naphthol, <B>- 3,6 -</B> di- sulfosaures Natrium werden in 250 Teilen konzentrierter Schwefelsäure gelöst. Hierauf trägt man zwischen 20<B>-</B> 40<B>0</B> unter gutem Rühren 40-50 Teile Benzoin ein. Nach eini gem Stehen verdünnt man mit etwa 250 Teilen Eis, filtriert und wäscht gegebenen falls mit Chlornatriumlösung etwas nach.
Der Rückstand wird dann in Wasser gelöst, mit Natriumearbonat oder -hydroxyd neutralisiert und, wenn nötig, von Verunreinigungen abfil- triert. Das neue Produkt kann durch Versetzen dieser klaren Lösung mit Chlornatrium oder andern ähnlich wirkenden Salzen isoliert wer den. Hierauf wird getrocknet und pulverisiert.
Die Aufarbeitung kann jedoch auch so vor sich gehen, dass man die mit viel Wasser verdünnte saure Kondensationsmasse mit Cal- ciumkarbonat oder -hydroxyd neutralisiert und nach dem Abfiltrieren von Caleiumsulfat mit Natriumearbonat in das Natriumsalz umsetzt.
Additional patent to main patent no. 160439. Process for the production of a new condensation product that can be used as a reservation agent. It has been found that a new condensation product is obtained if 2 moles of benzoin and 1 mole of 2-oxynaphthalene-3,6-disulfonic acid are condensed.
The new product forms a light-colored powder that easily dissolves in water. It is characterized by its affinity for animal fibers and should be used to reserve the wool against dyes of various classes.
<I> Example: </I> 40 parts of technical 2 <B> - </B> naphthol, <B> - 3.6 - </B> disulfonic acid sodium are dissolved in 250 parts of concentrated sulfuric acid. Then between 20 - 40 40 - 50 parts of benzoin are introduced with thorough stirring. After standing for a while, the mixture is diluted with about 250 parts of ice, filtered and, if necessary, rewashed with sodium chloride solution.
The residue is then dissolved in water, neutralized with sodium carbonate or hydroxide and, if necessary, filtered to remove impurities. The new product can be isolated by adding sodium chloride or other similarly acting salts to this clear solution. It is then dried and pulverized.
The work-up can, however, also proceed in such a way that the acidic condensation mass diluted with plenty of water is neutralized with calcium carbonate or hydroxide and, after the calcium sulfate has been filtered off, converted into the sodium salt with sodium carbonate.
