Patentiert im Deutschen Reiche vom 20. November 1912 ab.Patented in the German Empire on November 20, 1912.
Untersuchungen haben ergeben, daß man zu roten, Substantiven Farbstoffen, die durch Nachbehandlung mit Formaldehyd in ihren Echtheitseigenschaften verbessert werden, gelangen kann, wenn man die Farbstoffe nach Patent 208968 und dessen Zusätzen erneut diazotiert und die gebildeten Diazo- oder Tetrazoverbindungen mit Resorcin, m-Aminophenol, deren Homologen und Derivaten kombiniert.Research has shown that red, nouns can lead to dyes Post-treatment with formaldehyde can be improved in their fastness properties can, if the dyes according to patent 208968 and its additives are diazotized again and the diazo or tetrazo compounds formed with resorcinol, m-aminophenol, their homologues and derivatives combined.
Der Farbstoff aus 25 kg diazotiertem p-Nitrobenzoyl-m-phenylendiamin -\- m-Nitrobenzoyl-2-amino-5-oxynaphtalin-7-sulfosäure (gemäß Patentschrift 208968) wird mit 16 kg Nitrit fein verrührt, hierzu 60 kg Salzsäure gegeben und die gebildete Tetrazoverbindung mit 25 kg Resorcin sodaalkalisch gekuppelt. Das so erhaltene Endprodukt löst sich in Wasser, das mit Natronlauge alkalisch gehalten wird, leicht auf und färbt ungeheizte Baumwolle in gelbroten Tönen an.The dye from 25 kg of diazotized p-nitrobenzoyl-m-phenylenediamine - \ - m-nitrobenzoyl-2-amino-5-oxynaphthalene-7-sulfonic acid (according to patent specification 208968) is finely mixed with 16 kg of nitrite, 60 kg of hydrochloric acid are added and the tetrazo compound formed is coupled with 25 kg of resorcinol in a soda-alkaline manner. The end product thus obtained dissolves easily in water, which is kept alkaline with sodium hydroxide solution, and stains unheated cotton in yellow-red shades.
Der aus 36 kg p-nitrobenzoyl-p-phenylendiaminsulfosaurem Natrium -\-2 · p-Nitrobenzoylamino-5-oxynaphtalin-7-sulfosäure und nachträgliche Reduktion gemäß Patentschrift 217628 erhaltene Farbstoff wird in Wasser zu einem feinen Teig verrührt. Hierzu gibt man 16 kg Natriumnitrit und läßt dann 60 kg Salzsäure zulaufen. Wenn die Tetrazotierung vollendet ist, läßt man die Masse in 25 kg Rosorcin oder m-aminophenol sodaalkalisch einfließen. Es entsteht ein Farbstoff, der sich leicht in verdünnter Natronlauge auflöst und die Pflanzenfaser gelbrot anfärbt. Die gefärbte Pflanzenfaser wird durch Nachbehandlung mit Formaldehyd waschecht.The dye obtained from 36 kg of p-nitrobenzoyl-p-phenylenediaminesulfonic acid sodium - \ - 2 · p-nitrobenzoylamino-5-oxynaphthalene-7-sulfonic acid and subsequent reduction according to patent 217628 is stirred in water to form a fine dough. 16 kg of sodium nitrite are added and 60 kg of hydrochloric acid are then run in. When the tetrazotization is complete, the mass is poured into 25 kg of rosorcinol or m-aminophenol in an alkaline form. The result is a dye that dissolves easily in dilute sodium hydroxide solution and stains the plant fibers yellow-red. The dyed plant fiber becomes washable after treatment with formaldehyde.
