Description
Verfahren zur Darstellung eines Arvlaminonaphtalinderivates. Wie gefunden wurde, erhält man 4-(a- Naphtylamino) - 4'- amino-diphenylamirtsulfo- säure, wenn man 1-Aminonaphtalin und 4.4'- Dianrino-diphenylamin-2-sulfosäure durch Er hitzen auf höhere Temperatur irn offenen oder im Druckgefäss in Gegenwart von Bisulfitlauge kondensiert.
Beispiel: In einem verbleiten oder emaillierten Rührkessel mit Heizmantel und Rückfluss- kühler werden 140 Teile 1-Amitronaphtalin und 280 Teile 4.4'-Diamino-diphenylamin-2- strlfosäure mit 2000 Teilen Natriumbisulfit- lösung von 36 B6 und 2000 Teilen Wasser 50 Stunden unter Rühren gekocht. Die Auf arbeitung erfolgt wie in dem Zusatzpatent Nr.<B>134888</B> beschrieben.
Das Endprodukt ist mit dein gemäss diesem Zusatzpatent er hältliehen identisch.
Process for the preparation of an arvlaminonaphthalene derivative. As has been found, 4- (a-naphthylamino) -4'-aminodiphenylamirtsulfonic acid is obtained if 1-aminonaphthalene and 4,4'-dianrino-diphenylamine-2-sulfonic acid are heated to a higher temperature in an open or in a pressure vessel condensed in the presence of bisulfite liquor.
Example: In a leaded or enamelled stirred kettle with a heating jacket and reflux condenser, 140 parts of 1-amitronaphthalene and 280 parts of 4,4'-diamino-diphenylamine-2-strifoic acid are stirred with 2000 parts of sodium bisulfite solution of 36 B6 and 2000 parts of water for 50 hours cooked. The processing takes place as described in the additional patent no. <B> 134888 </B>.
The end product is identical to yours according to this additional patent.
