Description
Es hat sich gezeigt, daß das Harnstoffderivat folgender Konstitution:It has been shown that the urea derivative has the following constitution:
,NH-, NH-
CO-CO-
-Ν H2 -OH ^SO3H /SO3H -OH NH0 -Ν H 2 -OH ^ SO 3 H / SO 3 H -OH NH 0
das man beispielsweise durch Einwirkung von Phosgen auf 1 · 4-Aminophenol-2-nitro-6-sulfosäure und darauffolgende Reduktion erhalten kann, sich zur Herstellung wertvoller beizenfärbender Azofarbstoffe verwenden läßt. Die auf diese Weise erhältlichen Farbstoffe sind durch hervorragende Walk- und Lichtechtheit ausgezeichnet.for example, by the action of phosgene on 1x4-aminophenol-2-nitro-6-sulfonic acid and subsequent reduction can be obtained for the production of valuable stain-coloring Can use azo dyes. The dyes obtainable in this way are characterized by excellent mill and lightfastness excellent.
43,5 Gewichtsteile des oben genannten Harnstoffderivats werden durch Einwirkung von Nitrit in die Tetrazoverbindung übergeführt, die man daraufhin in sodaalkalischer Lösung mit 29 Teilen β - Naphtol kombiniert. Nach beendeter Farbstoff bildung wärmt man auf und salzt den Färbstoff aus. Er färbt Wolle in saurem Bade bräunlichrot; durch Nachchromieren werden die Färbungen schwarzviolett. Sie besitzen dann eine große WaIk- und Pottingechtheit sowie hervorragende Lichtechtheit. 43.5 parts by weight of the above-mentioned urea derivative are by the action of Nitrite converted into the tetrazo compound, which is then placed in a soda-alkaline solution combined with 29 parts of β-naphtol. After dye formation is complete, the product is warmed up and salt out the dye. He dyes wool brownish-red in an acid bath; by re-chrome plating the colorations become black-violet. You will then have a great and potting fastness as well as excellent light fastness.
Ersetzt man in vorigem Beispiel das ß-Naphtol durch die äquivalente Menge Phenylmethylpyrazolon, so erhält man einen Farbstoff, der Wolle in saurem Bade orange färbt. Durch Nachchromieren werden die Färbungen rot. Sie erhalten dabei eine hervorragende Echtheit.If in the previous example the ß-naphtol is replaced by the equivalent amount of phenylmethylpyrazolone, in this way a dye is obtained which dyes wool orange in an acid bath. By After chrome plating, the colors turn red. You get excellent authenticity.
An Stelle des Phenylmethylpyrazolons können unter Erzielung eines ähnlichen Effekts dessen nichtsulfurierte Derivate, wie z. B. Halogenphenylmethylpyrazolone usw., verwendet werden. Ebenso kann man das Naphtol durch andere Phenole der Naphtalin- oder Benzolreihe, wie z. B. Resorcin, Dioxynaphtalin usw., ersetzen. .Instead of the Phenylmethylpyrazolons can with achieving a similar effect of unsulfurized derivatives, such as. Halophenylmethylpyrazolones, etc., can be used. The naphthol can also be replaced by other phenols of the naphthalene or benzene series, such as B. resorcinol, dioxynaphthalene, etc. replace. .
