Description
Verfahren zur Herstellung eines neuen Zwischenproduktes. Es wurde gefunden, dass man ein neues Zwischenprodukt, das tertiäre K.ondensations- produkt von einem Mol. Cyanurchlorid mit einem Mol. 1-Aminobenzol-3-1La.rbonsäure und zwei Mol. 1 .8-Aminonaphthol-3.6-disulfo- säure, erhält,
wenn man auf ein 'Mo1. Cyanur- ühlorird in beliebiger Reihenfolge ein Mol. 1- A.minobenzol-3-karbonsäure und zwei Mal. 1. 8-Aminoil.aphthol-3. 6-disiilfosäure einwir ken lässt.
Diese Kondensation wird durch Zusam menrühren der Komponenten in einem geeig neten Verdünnungsmittel durchgeführt, und es wurde gefunden, dass Wasser als solches in überraschender Weise sehr gut geeignet ist. Das tertiäre Kondensationsprodukt aus einem Mol. Cvanurchlorid mit einem Mol. 1-Amino- benzol-3-karbonsäure und zwei Mol. 1.8- Aminonaphtliol-3.6-disulfosäure bildet als Alkalis.alz ein in Wasser lösliches, fast farb loses Pulver.
Es enthält kein reaktionsfähiges Chloratom mehr und stellt ein wertvolles Ausgangsmaterial zur Herstellung von Farb stoffen dar. Beispiel: 31,9 Teile 1.8-A.minonaphthol-3.6-di- sulfosäure werden in 500 Teilen Wasser unter Zusatz von 13,3 Teilen 30 %iger Natronlauge gelöst; mit 18,5 Teilen Cyanurchlorid versetzt und gerührt, bis die Komponenten verschwun den sind.
Die so erhaltene saure Lösung wird sehr vorsichtig fast genau neutralisiert und mit einer Lösung von 31,9 Teilen 1.8- Aminon.aphthol-3.6-disulfosäure, 13,3 Tei len 30 %iger Natronlauge und 30 Teilen I#a- triumacetat in 150 Teilen Wasser versetzt. Nach einigem Rühren ist die Aminonaphthol- sulfosäure beinahe verschwunden.
Hierauf wird mit Soda genau neutralisiert, mit einer Lösung von 14 Teilen 1-Aminobenzol-3-kar- bonsäure in 200 Teilen Wasser und 13,3 Tei len 30 %i,ger Natronlauge versetzt und län gere Zeit .am Rü:ekflusskühler gekocht.
Das tertiäre Kondensationsprodukt von einem Mol. Cyanurchlorid, einem Mol. 1-Amino- benzol-3-karbonsäure und zwei Mol. 1.8- Aminonaphth.ol-3.6-disulfosKure wird hier auf durch Aussalzen und Filtrieren isoliert.
Process for the production of a new intermediate product. It has been found that a new intermediate product, the tertiary condensation product of one mole of cyanuric chloride with one mole of 1-aminobenzene-3-1Larboxylic acid and two moles of 1,8-aminonaphthol-3,6-disulfonic acid , receives,
if you are on a 'Mo1. Cyanuruhlorird in any order one mole. 1- A.minobenzene-3-carboxylic acid and twice. 1. 8-Aminoil.aphthol-3. 6-disilfonic 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 tertiary condensation product of one mole of vanuric chloride with one mole of 1-aminobenzene-3-carboxylic acid and two moles of 1,8-aminonaphthiol-3,6-disulfonic acid forms, as an alkali salt, a water-soluble, almost colorless powder.
It no longer contains a reactive chlorine atom and is a valuable starting material for the production of dyes. Example: 31.9 parts of 1.8-A.minonaphthol-3.6-disulfonic acid are dissolved in 500 parts of water with the addition of 13.3 parts of 30% strength Sodium hydroxide solution dissolved; mixed with 18.5 parts of cyanuric chloride and stirred until the components have disappeared.
The acidic solution obtained in this way is very carefully and almost exactly neutralized and treated with a solution of 31.9 parts of 1,8-aminonaphthol-3,6-disulfonic acid, 13.3 parts of 30% strength sodium hydroxide solution and 30 parts of sodium acetate in 150 parts Water added. After some stirring, the aminonaphthol sulfonic acid has almost disappeared.
It is then precisely neutralized with soda, mixed with a solution of 14 parts of 1-aminobenzene-3-carboxylic acid in 200 parts of water and 13.3 parts of 30% sodium hydroxide solution and boiled on the reflux condenser for a long time.
The tertiary condensation product of one mole of cyanuric chloride, one mole of 1-aminobenzene-3-carboxylic acid and two moles of 1.8-aminonaphthol-3.6-disulfonic acid is isolated here by salting out and filtering.
