Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 189141. Verfahren zur Darstellung eines 1Vlonoazofarbstoffes. Das: vorliegende Patent betrifft ein Ver fahren zur Darstellung eines 1Monoazofarb- stoffes und ist dadurch gekennzeichnet, dass man 4-(N-o-Chlorbenzoyl-N-benzyl)-amido-l- amidobenzol dianotiert und mit N-2', 5'-Di- chlorbenzoyl-J-säure kuppelt.
<I>Beispiel:</I> 33,7 Teile 4-(N-o-Chlorbenzoyl-N-benzyl)- amido-l-amidobenzol werden mit 6,9 Teilen Nitrit und 25 Teilen Salzsäure dianotiert und in Gegenwart von überschüssigem Natrium acetat mit 41,2 Teilen N-2'; 5'-Dichlorben- zoyl-J-säure gekuppelt. Die Kupplung kann auch in Gegenwart von Natriumbicarbonat oder ähnlich schwachwirkenden Neutralisa- tionsmitteln vorgenommen werden.
Der isolierte- und getrocknete Farbstoff stellt ein orangerotes Pulver dar und färbt Wolle und Seide in lebhaften orangen Tönen.
<B> Additional patent </B> to main patent No. 189141. Process for the preparation of a 1-vlonoazo dye. The present patent relates to a process for the preparation of a monoazo dye and is characterized in that 4- (No-chlorobenzoyl-N-benzyl) -amido-l-amidobenzene is dianotated and with N-2 ', 5'-di - chlorobenzoyl-J-acid couples.
<I> Example: </I> 33.7 parts of 4- (no-chlorobenzoyl-N-benzyl) - amido-l-amidobenzene are dianotized with 6.9 parts of nitrite and 25 parts of hydrochloric acid and in the presence of excess sodium acetate 41.2 parts of N-2 '; 5'-dichlorobenzoyl-I-acid coupled. The coupling can also be carried out in the presence of sodium bicarbonate or similarly weak neutralizing agents.
The isolated and dried dye is an orange-red powder and dyes wool and silk in vivid orange tones.
