Description

  

  Verfahren zur Herstellung eines neuen Zwischenproduktes der Teerfarbenindustrie.    Es wurde gefunden,     :dass    man ein neues  Zwischenprodukt, das     Kondensationsprodukt     aus     Cyanurtrikarbonsäurechlorid,    und 1,8  Aminonaphthol-3,6--disulfosäure, erhält, wenn  man 1     Mol.        CyanurtrikaTbonsäurechlorid     auf 1     Mol.        1,8-Aminonaphtho#l-3,6-;disulfo-          säure    einwirken     lässt..     



  Das     Kondensationsprodukt    aus 1     Mol.          Cyanurtrikarbonsäurechlorid        und    1     Mol.        1,8-          Aminonaphthol-3,6-disulfosäure    bildet ein  gelbliches Pulver, welches. ein     wertvolles     Ausgangsmaterial zur Herstellung von Farb  stoffen darstellt.

           Beispiel:       In eine eiskalte Lösung von 36,3 Teilen       1,8-aminonaphthol-3,6-sulfos.surem    Natrium  in 1000 Teilen Wasser werden unter Rühren  26,8 Teile     Cya.nurtrikarbansäurechlorid,    die  mit Äther verdünnt, worden sind, zugegeben;

    es wird zirka. eine halbe Stunde bei niedri  ger Temperatur weiter gerührt,     Das        $on=            densationsprodukt    aus     1,8-Aminonaphthol-          3,6-sulfosäure    und     Cyanurtrikarbonsäurechlo-          rid    fällt     nach    dieser Zeit     aus,    es wird     fil-          triert,    gewaschen und getrocknet.



  Process for the production of a new intermediate product in the tar color industry. It has been found that: a new intermediate, the condensation product of cyanurtricarboxylic acid chloride and 1,8 aminonaphthol-3,6-disulphonic acid, is obtained if 1 mol. Of cyanuricarboxylic acid chloride is added to 1 mol. Of 1,8-aminonaphtho # l-3 , 6-; disulfonic acid leaves it to act.



  The condensation product of 1 mol. Cyanurtricarboxylic acid chloride and 1 mol. 1,8-aminonaphthol-3,6-disulfonic acid forms a yellowish powder which. represents a valuable starting material for the production of dyes.

           Example: 26.8 parts of Cya.nurtrikarbansäurechlorid, which have been diluted with ether, are added to an ice-cold solution of 36.3 parts of 1,8-aminonaphthol-3,6-sulfos.surem sodium in 1000 parts of water;

    it will be about. Stirring is continued for half an hour at a low temperature. The on = densation product of 1,8-aminonaphthol-3,6-sulfonic acid and cyanuricarboxylic acid chloride precipitates after this time, it is filtered, washed and dried.
