Description
Verfahren zur Herstellung eines neuen Zwischenproduktes. Beispiel: 31,9 Teile 1.8-Aminonaphtliol-3.6-di- sulfosäure werden in 500 Teilen Wasser un ter Zusatz von 18,3 Teilen 30 %iger Natron lauge gelöst, mit 18,5 Teilen Cyanurchlor.id versetzt und gerührt, bis die Komponenten verschwunden sind.
Die so erhaltene saure Lösung wird sehr vorsichtig fast genau neu tralisiert und hierauf mit einer Lösung aus 18,7 Teilen 1-Aminobenzol-2-oxy-5-chlor-3- karbonsäure in 200 Teilen Wasser und 13,3 Teilen 30 %iger Natronlauge versetzt.
Man rührt, bis die 1-Aminobenzol-2-oxy-5-chlor- 3-karbonsäure fast verschwunden ist, und iso liert das sekundäre Kondensat.ionsproduht aus einem Mol. Cyanurchlorid, einem Mol. 1 .
8 - Aminoaaphthol -<B>3.6</B> - disulfosäure und einem Mol. 1-Aminobenzol-2-oxy-5-chlor-3- karbonsäure durch Aussalzen. Es wurde gefunden, dass man ein neues Zwischenprodukt, das sekundäre Kondensa tionsprodukt von einem Mol. Cyanurohlorid mit einem Mol. 1.8-Aminonaphthol-3.6-di- sulfosäure und einem Mol. 1-Aminobenzol-2- oxy-5-chlor-3-ka.rbonsäure, erhält,
wenn man auf ein Mol. Cyanurchlorid in beliebiger Rei henfolge ein Mol. 1.8-Aminonaphthol-3.6- disulfosäure und ein Mol. 1- Aminobenzol-2- oxy-5-chlor-3-karbonsäure einwirken lässt.
Diese Kondensation wird durch Zusam- menrühren,der Komponenten in einem geeig neten Verdünnungsmittel durchgeführt, und es wurde gefunden, dass als solches Wasser in überraschender Weise sehr gut geeignet ist.
Das sekundäre Kondensationsprodukt aus einem Mol. Cyanurchlorid, einem Mol. 1..8- Aminonaphthal-3.6-disulfosäure und einem Mol. 1-Aminobenzol-2-oxy-5-Chlor-3-karbon- säure bildet ein in Wasser leicht lösliches, farbloses, kristallinisches Pulver. Es enthält noch ein reaktionsfähiges Chloratom und stellt ein wertvolles Ausgangsmaterial zur Herstellung von Farbstoffen dar.
Process for the production of a new intermediate product. Example: 31.9 parts of 1,8-aminonaphthiol-3,6-disulfonic acid are dissolved in 500 parts of water with the addition of 18.3 parts of 30% strength sodium hydroxide solution, mixed with 18.5 parts of cyanuric chloride and stirred until the components Have disappeared.
The acidic solution thus obtained is very carefully neutralized almost exactly and then treated with a solution of 18.7 parts of 1-aminobenzene-2-oxy-5-chloro-3-carboxylic acid in 200 parts of water and 13.3 parts of 30% strength sodium hydroxide solution offset.
The mixture is stirred until the 1-aminobenzene-2-oxy-5-chloro-3-carboxylic acid has almost disappeared, and the secondary condensation product is isolated from one mole of cyanuric chloride and one mole of 1.
8 - Aminoaaphthol - <B> 3.6 </B> - disulfonic acid and one mole of 1-aminobenzene-2-oxy-5-chloro-3-carboxylic acid by salting out. It has been found that a new intermediate product, the secondary condensation product of one mole of cyanuric chloride with one mole of 1.8-aminonaphthol-3.6-disulfonic acid and one mole of 1-aminobenzene-2-oxy-5-chloro-3- ka.rboxylic acid, receives,
if one mole of 1.8-aminonaphthol-3.6-disulfonic acid and one mole of 1- aminobenzene-2-oxy-5-chloro-3-carboxylic acid are allowed to act on one mole of cyanuric chloride in any order.
This condensation is carried out by stirring the components together in a suitable diluent, and it has been found that, surprisingly, water is very suitable as such.
The secondary condensation product of one mole of cyanuric chloride, one mole of 1..8-aminonaphthal-3,6-disulfonic acid and one mole of 1-aminobenzene-2-oxy-5-chloro-3-carbonic acid forms a readily soluble in water, colorless, crystalline powder. It still contains a reactive chlorine atom and is a valuable starting material for the production of dyes.
