Description
Verfahren zur Herstellung eines Azofarbstof%s. Es wurde gefunden, dass man zu neuen Azofarbstoffen gelangen kann, wenn man die bekannten durch Tetrazotierung von monoaminobenzoylierten Diaminen der Ben- zolreihe und Kuppeln an erster Stelle mit einer o-Oxykarbonsäure und an zweiter Stelle mit einer Aminonaphtolmono- bezw. disulfosäure erhältlichen Disazofarbstoffe weiterdiazotiert und mit m-Diamino-,
m-Amino-oxy- oder m-Dioxyverbindungen der Benzolreihe oder deren Monoazoderivaten kuppelt. Man erhält im allgemeinen rot- bis tiefschwarzbraune Nuancen auf Baumwolle, die sich durch eine gute neutrale und alkalische Ätzbarkeit auszeichnen.
Die neuen Farbstoffe besitzen gegenüber den bekannten entsprechenden Farbstoffen der p . p'-Diaminodiphenylreihe eine in der Regel verbesserte neutrale und alkalische Ätzbarkeit. Sie lassen sich selbstverständlich den üblichen Nachbehandlungsmethoden un terwerfen, z. B. mit Formaldehyd, falls man mit einer für diese Behandlung geeigneten Schlusskomponente gekuppelt hat, oder mit diazotiertem p-Nitranilin und dergleichen.
Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines Azo- farbstoffes. Das Verfahren besteht darin, dass man 1 Mol tetrazotierten p-Aminobenzoyl- p-phenylendiamins mit einem Gemisch von Salicylsäure und o-gresotinsäure, entspre chend 1 Mol, und 1 Mol 2,8-Aminonaphtol. 6-sulfonsäure kuppelt,
den so gebildeten Dis- azofarbstoff diazotiert und mit 1 Mol m-Phe- nylendiamin vereinigt.
Der neue Farbstoff färbt Baumwolle in tiefbraunen Tönen, die sich mit Formaldehyd nachbehandeln lassen. <I>Beispiel:</I> 62,6 Teile des in bekannter Weise durch Tetrazotieren von 1 Mol p-Aminobenzoyl-p- phenylendiamin und Kuppeln mit einem Mol eines Gemisches aus 80 % Salioylsäure und 20 0% o-gresotinsäure, sowie 1 Mol 2 .
8- Aminonaphtol - 6 - sulfonsäure erhältlichen Farbstoffes werden mit Wasser verrührt und mit 7 Teilen Natriumnitrit plus 30 Teilen Salzsäure 19,5 0 B6 diazotiert. Nach etwa 2 Stunden ist die Nitritaufnahme beendigt, und das Diazotierungsgemisch läuft zu einer mit 30 Teilen Soda versetzten Lösung von 11 Teilen m-Phenylerrdianrirr. Der Farbstoff ist nach seiner Fertigstellung ausgefallen und kann direkt gepresst werden. Er färbt Baum wolle in tief braunen Tönen an, die sich mit Formaldehyd nachbehandeln lassen.
Die Waschechtheit wird dadurch erheblich ver bessert, während die neutral und alkalisch vorzügliche Ätze nicht leidet.
Process for the preparation of an azo dye% s. It has been found that new azo dyes can be obtained if the known benzene series by tetrazotization of monoaminobenzoylated diamines of the benzene series and domes in the first place with an o-oxycarboxylic acid and in the second place with an aminonaphthol mono- or. disulfonic acid available disazo diazotized further and with m-diamino,
m-Amino-oxy or m-dioxy compounds of the benzene series or their monoazo derivatives couples. In general, reddish to deep black-brown shades are obtained on cotton, which are distinguished by good neutral and alkaline etchability.
The new dyes have compared to the known corresponding dyes of p. p'-diaminodiphenyl series generally improved neutral and alkaline etchability. You can of course un subject to the usual after-treatment methods, z. B. with formaldehyde, if you have coupled with a final component suitable for this treatment, or with diazotized p-nitroaniline and the like.
The present patent relates to a process for the production of an azo dye. The process consists in that 1 mol of tetrazotized p-aminobenzoyl-p-phenylenediamine with a mixture of salicylic acid and o-gresotinic acid, corresponding to 1 mol, and 1 mol of 2,8-aminonaphtol. 6-sulfonic acid couples,
the disazo dye thus formed is diazotized and combined with 1 mol of m-phenylenediamine.
The new dye dyes cotton in deep brown shades, which can be treated with formaldehyde. <I> Example: </I> 62.6 parts of in a known manner by tetrazotizing 1 mole of p-aminobenzoyl-p-phenylenediamine and coupling with a mole of a mixture of 80% salioic acid and 20 0% o-gresotinic acid, and 1 Mole 2.
8-aminonaphthol-6-sulfonic acid available dye are stirred with water and diazotized with 7 parts of sodium nitrite plus 30 parts of hydrochloric acid 19.5 ° B6. After about 2 hours, the uptake of nitrite is complete, and the diazotization mixture runs into a solution of 11 parts of m-phenylene oxide to which 30 parts of soda are added. The dye precipitated after its completion and can be pressed directly. He dyes cotton in deep brown shades that can be treated with formaldehyde.
The wash fastness is considerably improved, while the neutral and alkaline etching does not suffer.
