Description
Verfahren zur Herstellung eines neuen Zwischenproduktes. Es wurde gefunden, dass man ein neues Zwischenprodukt, das sekundäre Kondensa tionsprodukt von einem Hol. Cyanurchlorid mit einem Hol. 1.8-Aminonaphthol-3.6-di- sulfosäure und einem Mal. 1-Aminobenzol-2- karbonsäure, erhält, wenn man auf ein Hol.
Cyanurchlori-d in beliebiger Reihenfolge ein Hol. 1. 8 -Amin onahlithol-3 . 6 @- d@sulf osäure und ein Hol. 1-Aminobenzol-2'-karbonsäure einwirken lässt.
Diese Kondensation wird durch Zusam menrühren der Komponenten in einem<B>geeig-</B> neten Verdünnungsmittel durchgerührt, und es wurde gefunden, dass als solches Wasser iii überraschender Weise sehr gut geeignet ist. Das sekundäre Kondensationsprodukt aus einem Hol. Cyanurchlorid, einem Hol. 1.8- Aminonaplithol-3.6-disulfosäure und einem Hol. 1-Aminob enzol-2-harbonsäure bildet ein in Wasser leicht lösliches, farbloses, kristal linisches Pulver.
Es entli@ilt noch ein reak tionsfähiges Chloratom und stellt ein. wert volles Ausgangsmaterial zur Herstellung von Farbstoffen dar. Beispiel: 81,9 Teile 1.8-Aminonaphthol-3.6-di- sulfosäure werden in 500 Teilen Wasser unter Zusatz von 18;8 Teilen 30 %iger Natronlauge gelöst, mit 18,5 \feilen Cyanur- chlorid versetzt und gerührt, bis die Kompo nenten verschwunden sind.
Die so erhaltene saure Lösung wird sehr vorsichtig fast genau neutralisiert und hierauf mit einer Lösung aus 14 Teilen 1-Aminobenzol-2-karbonsäure in 200 Teilen Wasser und 13,3 Teilen 80 /aiger Natronlauge versetzt.
Man rührt, bis die 1- Aminobenzol-2-karbonsä-are fast verschwun den ist, und isoliert das sekundäre Konden sationsprodukt aus einem Hol. Cyanurchlo- rid, einem Hol. 1.8-Aminonaphthol-3.6-di.- sulfosäure und einem Hol. 1-Aminobenzol-2- karbonsäure durch Aussaizen.
Process for the production of a new intermediate product. It was found that a new intermediate product, the secondary condensation product of a Hol. Cyanuric chloride with a hol. 1.8-aminonaphthol-3.6-disulfonic acid and one time. 1-aminobenzene-2-carboxylic acid, obtained when one on a Hol.
Cyanurchlori-d a hol in any order. 1.8-Aminonahlithol-3. 6 @ - d @ sulfonic acid and a hol. 1-aminobenzene-2'-carboxylic acid can act.
This condensation is carried out by stirring the components together in a suitable diluent, and it has been found that water as such is surprisingly very suitable. The secondary condensation product from a haul. Cyanuric chloride, a hol. 1.8-aminonaplithol-3.6-disulfonic acid and a hol. 1-aminobenzene-2-harboxylic acid forms a colorless, crystalline powder that is easily soluble in water.
A reactive chlorine atom still escapes and ceases. valuable starting material for the production of dyes. Example: 81.9 parts of 1,8-aminonaphthol-3,6-disulfonic acid are dissolved in 500 parts of water with the addition of 18; 8 parts of 30% sodium hydroxide solution, with 18.5 parts of cyanuric chloride and stirred until the components have disappeared.
The acidic solution obtained in this way is very carefully neutralized almost exactly and then a solution of 14 parts of 1-aminobenzene-2-carboxylic acid in 200 parts of water and 13.3 parts of 80% sodium hydroxide solution is added.
The mixture is stirred until the 1-aminobenzene-2-carboxylic acid has almost disappeared, and the secondary condensation product is isolated from a hol. Cyanuric chloride, a hol. 1,8-aminonaphthol-3,6-di.-sulfonic acid and a hol. 1-aminobenzene-2-carboxylic acid by seeding.
