Description
Terfahren zur Herstellung eines neuen Zwischenproduktes. Es wurde gefunden, dass man ein neues Zwischenprodukt, das sekundäre Kondensa tionsprodukt von einem Mol. Cyanurchlorid mit einem Mol. 2.5-AminGnaphthol-7-sulfo- säure und einem Mol. 1-Amino-3-formyl- aminobenzol, erhält,
wenn man auf ein Mol. Cyanurchlorid in beliebiger Reihenfolge ein Mol. 2.5-Aminonaphthol-7-sulfosäure und ein Mol. 1-.Jlmino-3-formylaminobenzol ein wirken 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 2.5-Aminonaphthol-7-sulfosäure und einem Mol. 1-Amino-3-formylaminobenzol bildet ein in Wasser leicht lösliches, farbloses, kri stallinisches Pulver.
Es enthält noch ein reak- tionsfähiges Chloratom und stellt ein wert volles Ausgangsmaterial zur Herstellung von Farbstoffen dar. Beispiel: Eine fein verteilte Aufschlemmung von 18,5 Teilen Cyanurchlorid in 1000 Teilen Wasser wird mit Salzsäure schwach sauer gestellt und nach und nach bei 0 unter Rüh ren mit einer Lösung von 26,2 Teilen 2 . 5 aminonaphthol-7-suifosauremNatrium in 500 Teilen Wasser versetzt, wobei man durch Zu gabe von Sololösung (im ganzen 5,3 Teile) die Reaktion immer schwach sauer hält.
Zu der so erhaltenen klaren Lösung, die mit Soda genau neutralisiert worden ist, fügt man nun<B>13,7</B> Teile 1-Amino-3-formylamino- benzol und rührt weiter, bis dieses ver schwunden ist. Das gebildete Kondensations produkt aus einem Mol. Cyanurchlorid, einem Mol. 2.5-Aminonaphthol-7-sulfosäure und einem Mol. 1-Amino-3-formylaminoben- zol wird hierauf, nach abermaligem Neutrali sieren dar Reaktionsflüssigkeit mit Soda lösung, durch Aussalzen isoliert.
Proceeding to manufacture a new intermediate product. It has been found that a new intermediate, the secondary condensation product of one mole of cyanuric chloride with one mole of 2,5-amine-7-naphthol-7-sulfonic acid and one mole of 1-amino-3-formylaminobenzene, is obtained,
if one mole of 2,5-aminonaphthol-7-sulfonic acid and one mole of 1-imino-3-formylaminobenzene 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 from one mol. Cyanuric chloride, one mole of 2,5-aminonaphthol-7-sulfonic acid and one mole. 1-Amino-3-formylaminobenzene forms a colorless, crystalline powder which is readily soluble in water.
It still contains a reactive chlorine atom and is a valuable starting material for the production of dyes. Example: A finely divided slurry of 18.5 parts of cyanuric chloride in 1000 parts of water is made slightly acidic with hydrochloric acid and gradually at 0 while stirring ren with a solution of 26.2 parts 2. 5 aminonaphthol-7-suifosauremNatrium in 500 parts of water are added, whereby the reaction is always kept weakly acidic by adding solo solution (5.3 parts in total).
13.7 parts of 1-amino-3-formylamino-benzene are now added to the clear solution thus obtained, which has been precisely neutralized with soda, and the mixture is stirred until it has disappeared. The condensation product formed from one mole of cyanuric chloride, one mole of 2,5-aminonaphthol-7-sulfonic acid and one mole of 1-amino-3-formylaminobenzene is then isolated by salting out after the reaction liquid has been neutralized again with soda solution.
