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.
