Description
Verfahren zur Herstellung eines substantiven Azofarbstoifes. Aus dem französischen Zusatzpatent Nr. 22841 (Zusatz zum französischen Haupt patent Nr. 481190) sind kupferbare Azo- farbstoffe bekanntgeworden, die durch Ver einigen von diazotierten 1-Oxy-2-amino- benzolsulfamiden mit N-Derivaten der 2- Amino-5-oxynaphthalin-7-sulfonsäure erhal ten werden.
Diese Farbstoffe eignen sich als Kupferkomplexe oder als Nachkupferungs- farbstoffe zum Färben der Cellulosefaser, wobei lichtechte rote, violette bis blaue Fär bungen entstehen.
Es wurde nun gefunden, dass neue, sub- stantive, zur Metallkomplexbildung befähigte Azofarbstoffe erhalten werden, die sich ge genüber den erwähnten bekannten Farb stoffen durch eine bessere Affinität zur Cel- lulosefaser auszeichnen, wenn man diazotierte 1- Oxy - 2 - aminobenzolcarbonsäureamide mit der 2-Amino-5-oxynaphthalin-7-sulfonsäure bezw. mit N-Derivaten dieser Säure ver einigt.
Je nach dem vorgesehenen Verwendungs zweck können diese Farbstoffe in Substanz oder auf der Faser in Metallkomplexe, ins besondere Kupferkomplexe, übergeführt wer den, wobei die Echtheitseigenschaften der Farbstoffe wesentlich verbessert werden.
Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines sub- stantiven, zur Metallkomplexbildung be fähigten Azofarbstoffes, dadurch gekenn zeichnet, dass diazotiertes 1-Oxy-2-amino- benzol - 4 - carbonsäure - phenylamid mit 2 Phenylamino- 5 -oxynaphthalin-7-sulfonsäure in alkalischem Medium vereinigt wird.
Der neue Farbstoff färbt Baumwolle aus schwach alkalischem Bade, welches Kupfer sulfat und weinsaures Natrium gelöst ent hält, in echten rotvioletten Tönen. <I>Beispiel:</I> 22,8 Gewichtsteile 1-Oxy-2-aminobenzol- 4-carbonsäurephenylamid werden unter Zu satz von 6,9 Gewichtsteilen Natriumnitrit und 27 Gewichtsteilen konz. Salzsäure bei 0 diazotiert und die Diazoverbindung mit 31,
5 Gewichtsteilen 2 - Phenylamino - 5 - oxynaph- thalin-7-sulfonsäure, die als Natriumsalz unter Zusatz von 100 Gewichtsteilen 20 % igem Calciumhydroxyd in 1000 Gewichtsteilen Wasser gelöst wurden, vereinigt. Nach 4 Stunden wird der gebildete Farbstoff durch Zusatz von Salzsäure abgeschieden, in das Natriumsalz übergeführt und getrocknet.
Der neue Farbstoff stellt ein dunkles Pulver dar und färbt Baumwolle aus schwach alkalischem Bade, welches Kupfersulfat und weinsaures Natrium gelöst enthält, in echten rotvioletten Tönen an.
Process for the production of a substantive azo dye. From the French additional patent no. 22841 (addition to the French main patent no. 481190) copperable azo dyes have become known which are produced by combining diazotized 1-oxy-2-aminobenzenesulfamides with N-derivatives of the 2-amino-5- oxynaphthalene-7-sulfonic acid can be obtained.
These dyes are suitable as copper complexes or as post-copper dyes for dyeing cellulose fibers, producing lightfast red, violet to blue colorations.
It has now been found that new, substantial azo dyes capable of forming metal complexes are obtained which are distinguished from the known dyes mentioned by a better affinity for cellulose fibers when diazotized 1-oxy-2-aminobenzolcarboxamides are used with the 2-Amino-5-oxynaphthalene-7-sulfonic acid respectively. united with N-derivatives of this acid.
Depending on the intended use, these dyes can be converted into metal complexes, in particular copper complexes, in substance or on the fiber, the fastness properties of the dyes being significantly improved.
The subject matter of the present patent is a process for the production of a sub- stantive azo dye capable of metal complex formation, characterized in that diazotized 1-oxy-2-aminobenzene-4-carboxylic acid-phenylamide with 2-phenylamino-5-oxynaphthalene-7 sulfonic acid is combined in an alkaline medium.
The new dye dyes cotton from a weakly alkaline bath, which contains dissolved copper sulfate and tartaric acid, in real red-violet tones. <I> Example: </I> 22.8 parts by weight of 1-oxy-2-aminobenzene-4-carboxylic acid phenylamide are added with 6.9 parts by weight of sodium nitrite and 27 parts by weight of conc. Hydrochloric acid diazotized at 0 and the diazo compound with 31,
5 parts by weight of 2-phenylamino-5-oxynaphthalene-7-sulfonic acid, which were dissolved as the sodium salt with the addition of 100 parts by weight of 20% calcium hydroxide in 1000 parts by weight of water, combined. After 4 hours, the dye formed is deposited by adding hydrochloric acid, converted into the sodium salt and dried.
The new dye is a dark powder and dyes cotton from a weakly alkaline bath, which contains dissolved copper sulfate and tartrate of sodium, in real red-violet tones.
