KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. PATENTSCHRIFTPATENT LETTERING - JVl 222511 -KLASSE 22 a. GRUPPE - JVl 222511 - CLASS 22 a. GROUP Verfahren zur Darstellung von gelben Wollfarbstoffen.Process for the preparation of yellow wool dyes. Patentiert im Deutschen Reiche vom 20. Juni 1909 ab.Patented in the German Empire on June 20, 1909. Es wurde gefunden, daß durch Kombination des β - Diazonaphtalins mit i-Sulfoaryl - 3 - methyl - 5 - pyrazolon gelbe Wollfarbstoffe entstehen, welche sehr farbkräftig sind und, obwohl sie in dem großen Moleküle nur eine Sulfogruppe enthalten, überraschenderweise für die praktische Verwendung in der Färberei genügend leicht löslich sind. Sie besitzen ferner ein vorzügliches Egalisierungs-ίο vermögen und färben, entsprechend dem größeren Moleküle, Wolle in rötlicher gelben Tönen an als der bekannte Anilinfarbstoff.It has been found that by combining the β-diazonaphthalene with i-sulfoaryl - 3 - methyl - 5 - pyrazolone yellow wool dyes are produced, which are very colorful and, although they contain only one sulfo group in the large molecule, surprisingly are sufficiently readily soluble for practical use in dyeing. You own also an excellent leveling ίο ability and coloring, according to the larger molecules, wool in reddish yellow tones than the well-known aniline dye. Beispiel:Example: Die aus 7,2 Teilen ß-Naphtylamin in üblicher Weise erhaltene Diazoverbindung läßt man in eine mit Eis gekühlte Lösung von 12,7 Teilen p-Sulfophenylmethylpyrazolon und 17,5 Teilen Soda in 300 Teilen Wasser einfließen. Nach Vollendung der Kombination erwärmt man die Flüssigkeit auf 70 ° und fällt den Farbstoff mit Salz aus. Er ist in Wasser ziemlich leicht löslich und färbt Wolle sehr gleichmäßig in gelben Tönen an.The diazo compound obtained from 7.2 parts of ß-naphthylamine in the usual way is left in an ice-cooled solution of 12.7 parts of p-sulfophenylmethylpyrazolone and 17.5 parts Pour soda into 300 parts of water. After completing the combination, heat the Liquid to 70 ° and the dye precipitates with salt. He's pretty in water Easily soluble and stains wool very evenly in yellow tones. In gleicher Weise kann man die Kombinationen mit den Isomeren und Homologen des ι - ρ - SuIf0phenyl - 3 - methyl - 5 - pyra zolons bzw. deren Chlorsubstitutionsprodukten ausführen, also z. B. mit i-m-Sulfophenyl-3 - methyl - 5 - pyrazolon, 1 - ρ - SuIfο - ο - tolyl-3 - methyl - 5 - pyrazolon, ι - ο - Chlor - ρ - sulfo- ! phenyl - 3 - methyl - 5 - pyrazolon, 1 - ο - Chlor - m- ! sulfophenyl - 3 - methyl - 5 -pyrazolon, i-p-Chlorm-sulfophenyl - 3 - methyl - 5 - pyrazolon, 1-4-Sulfo -2:5- dichlorphenyl - 3 - methyl - 5 - pyrazolon. Alle diese Farbstoffe sind in Wasser ziemlich leicht löslich und färben Wolle sehr gleichmäßig in gelben Tönen.In the same way one can use the combinations with the isomers and homologues des ι - ρ - sulfophenyl - 3 - methyl - 5 - pyra zolons or run their chlorine substitution products, so z. B. with i-m-sulfophenyl-3 - methyl - 5 - pyrazolone, 1 - ρ - SuIfο - ο - tolyl-3 - methyl - 5 - pyrazolone, ι - ο - chlorine - ρ - sulfo- ! phenyl - 3 - methyl - 5 - pyrazolone, 1 - ο - chlorine - m- ! sulfophenyl - 3 - methyl - 5 -pyrazolone, i-p-chlorom-sulfophenyl - 3 - methyl - 5 - pyrazolone, 1-4-sulfo -2: 5 - dichlorophenyl - 3 - methyl - 5 - pyrazolone. All of these dyes are fairly readily soluble in water and they dye wool a lot evenly in yellow tones.
