Description
Verfahren zur Herstellung eines neuen Zwischenproduktes der Teerfarbenindustrie. Es wurde gefunden, dass man ein neues Zwischenprodukt, das sekundäre Kondensa tionsprodukt von einem Hol. Cyanurchlorid mit zwei Hol. 1,3-Phenylendiaminmonooxa- minsäure, erhält, wenn man auf ein Hol. Cya- nurchlorid zwei Hol. 1,3-Phenylendia.minmo- nooxaminsäure einwirken lässt.
Diese Kondensation wird durch Zusa.m- xnenrühren der Komponenten in einem geeig neten Verdünnungsmittel durchgeführt, und es wurde gefunden, dass Wasser als solches in überraschender Weise sehr gut geeignet ist. Das sekundäre Kondensationsprodukt aus einem Hol. Cyanurchlorid mit zwei Hol. 1.,3-Phenylendiaminmonooxaminsäure bildet ein graues Pulver, das über<B>300'</B> schmilzt. ES enthält noch ein reaktionsfähiges Chlor atom und stellt ein wertvolles Ausgangsma terial zur Herstellung von Farbstoffen dar.
Beispiel: In eine Suspension von 18,5 Teilen Cya- nurchlorid in der 20fachen Menge Wasser werden in der Kälte 20,2 Teile 1,3-penyler=- diatninmonooxaminsaures Natrium in 200 Teilen Wasser langsam zugerührt. Gleich zeitig wird die entstehende Salzsäure der massen neutralisiert, dass die Reaktionsmasse immer lakmussauer bleibt.
Sobald 3,6 Teile Salzsäure frei geworden sind, wird genau neu tralisiert, bei gewöhnlicher Temperatur noch mals 20,5 Teile 1,3-phenylendiaminmonooxa- minsaures Natrium zugegeben und ea. 1 Stunde bei 40 bis<B>50'</B> gerührt. Es werden unter Bildung des sekundären Koudens.ations- produktes aus einem Mol. Cyanurchlorid und zwei Mol. 1,3 - Phenylen.dia,minmonooxamin- säure 3,6 Teile Salzsäure frei. Das Konden sationsprodukt wird durch Filtration isoliert.
Process for the production of a new intermediate product in the tar color industry. It was found that a new intermediate product, the secondary condensation product of a Hol. Cyanuric chloride with two hol. 1,3-Phenylenediamine monooxamic acid, obtained when you get on a Hol. Cyanuric chloride two hol. 1,3-Phenylenedia.minmonoxamic 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 with two hol. 1., 3-Phenylenediamine monooxamic acid forms a gray powder that melts over <B> 300 '</B>. ES still contains a reactive chlorine atom and is a valuable starting material for the production of dyes.
Example: 20.2 parts of 1,3-penylated sodium monooxamic acid in 200 parts of water are slowly stirred into a suspension of 18.5 parts of cyanuric chloride in 20 times the amount of water. At the same time, the resulting hydrochloric acid is neutralized in such a way that the reaction mixture always remains dry.
As soon as 3.6 parts of hydrochloric acid have been released, the process is precisely neutralized, and a further 20.5 parts of 1,3-phenylenediamine monooxamic acid sodium are added at normal temperature and about 1 hour at 40 to 50 ' touched. 3.6 parts of hydrochloric acid are liberated, with the formation of the secondary koudensation product from one mole of cyanuric chloride and two moles of 1,3-phenylene-dia, minmonooxamic acid. The condensation product is isolated by filtration.
