Description
Verfahren zur Herstellung eines neuen Zwischenproduktes der Teerfarbenindustrie. Es wurde gefunden, da3 man ein neues Zwischenprodukt, das symmetrische ditertiäre Kondensationsprodukt von zwei Mol. Cyanur- chlorid, einem 141o1. 1,4-Phenylen.diamin, zwei Mol. 1,3 - Phenylendiamin - 4 - sulfosäure und zwei Mol. Anilin, erhält, wenn man auf zwei 11o1.
Cyanurchlorid in beliebiger Reihenfolge ein Mol. 1,4-Phenylendiamin, zwei Mol. 1,,3- Plienylendiamin-4-sulfosäure und zwei Mol. Anilin einwirken lässt.
Diese Kondensation wird durch Zusam- inenrühren der Komponenten in einem geeig neten Verdünnungsmittel .durchgeführt, und es wurde gefunden, dass Wasser als solches in überraschender Weise sehr .gut geeignet ist.
Das symmetrische clitertiäre Kondensoüons- produkt aus zwei Mol. Cyanurchlorid mit einem Mol. 1,4-Phenylendiamin, zwei Mol. <B>1,3</B> - Plienylendiamin-4-sulfosäure und zwei Mol. Anilin bildet als Alkalisalz ein in Was ser lösliches, fast farbloses Pulver. Es enthält kein reaktionsfähiges Chloratom mehr und stellt ein wertvolles Ausgangsmaterial zur Herstellung von Farbstoffen dar.
<I>Beispiel:</I> In eine Aufsehlemmung von 37 Teilen Cyanurclilorid und 1000 Teilen Wasser giesst man eine Lösung aus<B>37,6</B> Teilen 1,3-Phenyl- endiamin-4-sulfosäure und 10,6 Teilen Soda in 1000 Teilen Wasser. Die Temperatur wird hei 0 gehalten und die gebildete .Mineral säure neutralisiert.
Sobald die Komponenten verschwunden sind, fügt man 10,8 Teile 1,4- Phenylendi.amin hinzu und rührt mehrere Stunden bei 40 bis <B>50'.</B> Hierauf neutralisiert man genau, fügt 18,6 Teile Anilin hinzu und kocht einige Zeit am Rüekflussliühler. Nach dem Erkalten wird das symmetrische diter- tiäre Kondensationsprodukt aus zwei Mol. Cyanurchlorid, einem Mol. 1,4-Plienylendia- min, zwei Mol. 1,
3 Phenylendiamin-4-sulfo- säure und zwei Mol. Anilin durch Aussahen und Aussäuern isoliert.
Process for the production of a new intermediate product in the tar color industry. It has been found that a new intermediate, the symmetrical ditertiary condensation product of two moles of cyanuric chloride, a 141o1. 1,4-phenylenediamine, two moles. 1,3-phenylenediamine-4-sulfonic acid and two moles. Aniline, are obtained when one on two 11o1.
Cyanuric chloride, one mole of 1,4-phenylenediamine, two moles of 1, 3-plienylenediamine-4-sulfonic acid and two moles of aniline can act in any order.
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 symmetrical clitertiary condensation product of two moles of cyanuric chloride with one mole of 1,4-phenylenediamine, two moles of 1,3-plienylenediamine-4-sulfonic acid and two moles of aniline as the alkali salt forms an in Water soluble, almost colorless powder. It no longer contains a reactive chlorine atom and is a valuable starting material for the production of dyes.
<I> Example: </I> A solution of <B> 37.6 </B> parts of 1,3-phenylenediamine-4-sulfonic acid and 10, is poured into a suspension of 37 parts of cyanuric chloride and 1000 parts of water 6 parts of soda in 1000 parts of water. The temperature is kept hot and the mineral acid formed is neutralized.
As soon as the components have disappeared, 10.8 parts of 1,4-phenylenediamine are added and the mixture is stirred for several hours at 40 to 50 '. This is followed by exactly neutralization, 18.6 parts of aniline are added and cooks for a while on the Rüekflussli cooler After cooling, the symmetrical diter- tiary condensation product of two moles of cyanuric chloride, one mole of 1,4-plienylenediamine, two moles of 1,
3 phenylenediamine-4-sulfonic acid and two moles. Aniline isolated by sighting and acidifying.
