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.
