Description
Verfahren zur Herstellung eines neuen Zwischenproduktes. Es wurde gefunden, dass man ein, neues Zwischenprodukt, das sekundäre Kondensa tionsprodukt von einem Mol. Cyanurchlorid mit zwei Nol. 1 # 8-Aminonaphthol-3 # 6-di- sulfosäure, erhält,
wenn _ man .auf ein Mol. Cyanurchlorid zwei Mol. 1 # 8-Aminonaphthol- 3. 6-disulfosäure einwirken lässt.
Diese Kondensation wird durch Zusam menrühren der Komponenten in einem geeig neten Verdünnungsmittel durchgeführt, und es wurde gefunden, da.ss als solches Wasser in überraschender Weise sehr gut .geeignet ist. Das sekundäre Kondensationsprodukt aus einem Mol. Cyanurchlorid mit zwei Mol. 1. 8- Aminonafphthol-3 . 6-disulfosäure bildet ein in Wasser leicht lösliches, kristallinisches, fast farbloses Pulver.
Es enthält noch ein reak tionsfähiges Chloratom und stellt ein wert volles Ausgangsmaterial zur Herstellung von Farbstoffen dar.
Beispiel: 31,9 Teile 1.8-Aminonaphthol-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 81,9 Teilen 1.8- Alminonaphthol=3. 6-disulfosäure, 13,8 Teilen 30 %iger Natronlauge und<B>"30</B> Teilen Na triumacetat in 150 Teilen Wasser versetzt.
Nach einigem Rühren ist die Aminonaphthol- sulfosä,ure beinahe verschwunden und das be reits teilweise .ausgeschiedene sekundäre Kon densationsprodukt aus einem- Mol. Cyanur- chlorid und zwei Mol. 1 # 8-Aminonaphthol- 3.6-disulfosäure wird durch Kochsalzzusatz vollständig .gefällt und filtriert.
Process for the production of a new intermediate product. It has been found that a, new intermediate, the secondary condensation product of one mole. Cyanuric chloride with two Nol. 1 # 8-aminonaphthol-3 # 6-disulfonic acid, receives,
if two moles of 1 # 8-aminonaphthol-3. 6-disulfonic acid are allowed to act on one mole of cyanuric chloride.
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 with two moles of 1. 8-aminonafphthol-3. 6-disulfonic acid forms a crystalline, almost colorless powder that is easily soluble in water.
It still contains a reactive chlorine atom and is a valuable starting material for the production of dyes.
Example: 31.9 parts of 1,8-aminonaphthol-3,6-disulfonic acid are dissolved in 500 parts of water with the addition of 13.3 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 obtained in this way is very carefully neutralized almost exactly and with a solution of 81.9 parts of 1,8-alminonaphthol = 3 6-disulfonic acid, 13.8 parts of 30% strength sodium hydroxide solution and 30 parts of sodium acetate in 150 parts of water are added.
After some stirring, the aminonaphthol sulfonic acid has almost disappeared and the secondary condensation product, which has already partially separated out, consisting of one mole of cyanuric chloride and two moles of 1 # 8-aminonaphthol-3,6-disulfonic acid, is completely precipitated and filtered.
