Description
Verfahren zur Herstellung eines neuen Zwischenprodukf.es der Teerfarbenindustrie. Es wurde gefunden, dass man ein neues Zwischenprodukt, das tertiäre Kondensations. produkt von einem 141o1. Cyanurchlorid mit einem Mol. 1-Oxy-2,4-cli.aminobenzol-6-sülfo- säure und zwei Mol. Anilin, erhält,
wenn man auf ein Mol. Cyanurohlorid in beliebiger Rei henfolge ein Mol. 1-Oxy-2-nitro-4-aminoben- zol-6-sulfosäure und zwei 142o1. Anilin einwir ken lässt und das so erhaltene Produkt redu ziert.
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 Konden.astionspro.dukt aus einem Mol. Cyanurchlorid mit einem Mol. 1-Oxy- 2,4-dia.minobenzol-6-sulfosäure und zwei Mol. Anilin bildet als Alkalisalz ein in Wasser lösliches, fast farbloses Pulver.
Es enthält kein reaktionsfähiges Chloratom mehr und stellt ein wertvolles Ausgangsmäterial zur Herstellung von Farbstoffen dar. <I>Beispiel:</I> In eine Suspension von 18,5 Teilen Cya- nurehlorid in der 20fachen Menge Wasser werden in der Kälte eine Lösung von 25,6 Teilen 1-oxy - 2 - nitro-4-aminobenzol-6-sulfo- saures Natrium langsam eingetragen.
Sobald 3,65 Teile Salzsäure- gebildet und neutralisiert worden sind, werden 9,3 Teile Anilin zuge setzt, und so lange bei gewöhnlicher Tem peratur gerührt, bis wieder 3,65 Teile Salz säure frei geworden sind. Diese werden aber mals neutralisiert.
Durch nochmaligen Zusatz von 9,3 Teilen Anilin und Kochen :am Rück fluss erhält man hierauf das tertiäre Konden sationsprodukt aus einem Mol. Cyanurchlorid, einem Mol. 1 - Oxy-2-nitro-4-aminobenzol-6- sulfosäure und zwei Mol. Anilin. Dieses wird in wässeriger Lösung mit Eisenfeile und Es sigsäure reduziert.
Aus der eisenfreien Re- duktionsflüssigkeit wird dann das tertiäre Kondensationsprodukt aus einem 1101. Cya- nurchlorid, einem Mol. 1-Oxy-2,4-diamino- benzol - 6 - sulfosäure und zwei Mol. Anilin durch Aissäuern isoliert.
Process for the production of a new intermediate product in the tar color industry. It has been found that one can produce a new intermediate, the tertiary condensation. product from a 141o1. Cyanuric chloride with one mole of 1-oxy-2,4-cli.aminobenzene-6-sulphoic acid and two moles of aniline,
if you add one mole of 1-oxy-2-nitro-4-aminobenzene-6-sulfonic acid and two 142o1 to one mole of cyanuric chloride in any order. Aniline can act and the product thus obtained is reduced.
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 from one mole of cyanuric chloride with one mole of 1-oxy-2,4-dia.minobenzene-6-sulfonic acid and two moles of aniline, as an alkali salt, forms 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. <I> Example: </I> In a suspension of 18.5 parts of cyanuric chloride in 20 times the amount of water, a solution of 25 , 6 parts of 1-oxy - 2 - nitro-4-aminobenzene-6-sulfo-acid sodium slowly entered.
As soon as 3.65 parts of hydrochloric acid have been formed and neutralized, 9.3 parts of aniline are added and the mixture is stirred at the usual temperature until 3.65 parts of hydrochloric acid are released again. But these are neutralized times.
By repeated addition of 9.3 parts of aniline and boiling: on reflux, the tertiary condensation product is then obtained from one mole of cyanuric chloride, one mole of 1-oxy-2-nitro-4-aminobenzene-6-sulfonic acid and two moles. Aniline. This is reduced in an aqueous solution with iron files and acetic acid.
The tertiary condensation product of a 1101th cyanuric chloride, one mole of 1-oxy-2,4-diamino-benzene-6-sulfonic acid and two moles of aniline is then isolated from the iron-free reducing liquid by acidification.
