Description
Zusatzpatent zum Hauptpatent Nr. 200369. Verfahren zur Herstellung eines Küpenfarbstoffes. Vorliegendes Patent bezieht sich auf ein Verfahren zur Herstellung eines Küpenfarb- Stoffes, dadurch gekennzeichnet, dass man ein Dicarbonsäuredichlorid der Formel:
EMI0001.0007
mit 1-Amino-5-benzoylaminoanthrachinon im Molekularverhältnis 1 : 2 kondensiert.
Der So erhaltene Farbstoff löst sich in konzentrierter Schwefelsäure mit braun oranger Farbe und färbt Baumwolle aus vio letter Hüpe in rotstichig-gelben Tönen von hervorragenden Echtheitseigenschaften. <I>Beispiel:
</I> Durch Kondensation von 4,4'-Diamino- benzophenon mit 2 Molekülen 4-Nitrosoben- zoesäure-methylester, anschliessende Versei- fung und Umsetzung mit Phosphorpenta- chlorid erhält man ein Dicarbonsäuredichlo- rid der Formel:
EMI0001.0024
das aus Chlorbenzol in fleischfarbenen Na deln vom Schmelzpunkt 242' C kristallisiert.
51 Teile dieser Verbindung werden bei etwa<B>160'</B> C langsam unter Rühren in eine Lösung von 69 Teilen 1-Amino-5-benzo5#1- aminoanthrachinon in etwa 700 Teilen o-Diclilorbenzol eingetragen. Nach etwa zwei stündigem Rühren bei etwa '-)00'C lässt man auf<B>IM'</B> C erkalten, saugt das gebildete Kondensationsprodukt ab und trocknet es.
Additional patent to main patent no. 200369. Process for the production of a vat dye. The present patent relates to a process for the production of a vat dye, characterized in that a dicarboxylic acid dichloride of the formula:
EMI0001.0007
condensed with 1-amino-5-benzoylaminoanthraquinone in a molecular ratio of 1: 2.
The dye obtained in this way dissolves in concentrated sulfuric acid with a brownish-orange color and dyes cotton from vio letter Hüpe in reddish-yellow shades with excellent fastness properties. <I> example:
</I> The condensation of 4,4'-diamino benzophenone with 2 molecules of methyl 4-nitrosobenzoate, subsequent saponification and reaction with phosphorus pentachloride gives a dicarboxylic acid dichloride of the formula:
EMI0001.0024
which crystallizes from chlorobenzene in flesh-colored needles with a melting point of 242 ° C.
51 parts of this compound are slowly introduced into a solution of 69 parts of 1-amino-5-benzo5 # 1-aminoanthraquinone in about 700 parts of o-diclilobenzene at about 160.degree. C. with stirring. After stirring for about two hours at about '-) 00'C, the mixture is left to cool to <B> IM' </B> C, the condensation product formed is filtered off with suction and dried.
