Description
Verfahren zur Herstellung eines Kondensationsproduktes. Es wurde gefunden, dass. man durcli Ko-n- densation von 1-Halagen-2-nitro-4-eyauben- zolen mit aromatisclien Aminen Konden sationsprodukte der Diphenylaminreilie er hält, #die sieh insbasondere zum Färben von Lacken, und zum Färben und Dru-,ken,
von Acetatseide eignen. Man erhält auf Aoetat- seide lebhaft grünstichig-gelbe bis orange Farbtöne von hervorragender Lichtechtheit.
vorliegendes Patent bezieht sieh nun auf eiii Verfahren. zur Herstellung eines Konden sationsproduktes, dadurch gekennzeichnet, .dass man 1-Clilor-2-nitro-4-eyauben#z#ol mit Anilin kondensiert.
Dast, so erhaltene 2-Nitro-4-eyandiplienyl- amin kristallisiert aus Methanel. in gelben Kristallen vom Smp. <B>126</B> 'bis<B>127 '</B> und f #Lrbt und #druckt Acotateei-cle in gelben Tönen von Uervorragünder Liehteahtheit. <I>Beispiel:
</I> <B>18,5</B> Teile l#Chl#o#r-,2#-nitro-4-eyaubenzol werden mit etwa 120 Teilen Alkohol und 20 Teilen Anilin mehrere Stunden. unter Rück- flusskühlung zum Sieden erhitzt. Beim Er halten sssheidet sich das gebildete Konden sationsprodukt in gelben Kristallen aus.
Process for the production of a condensation product. It has been found that condensation products of the diphenylamine range are obtained by co-condensation of 1-Halagen-2-nitro-4-eyaubenzolen with aromatic amines, # which are particularly useful for coloring lacquers, and for dyeing and Printing,
of acetate silk are suitable. Vivid greenish-yellow to orange shades of excellent lightfastness are obtained on acetate silk.
This patent now relates to a process. for the production of a condensation product, characterized in that 1-Clilor-2-nitro-4-eyauben # z # ol is condensed with aniline.
The 2-nitro-4-eyandiplienylamine thus obtained crystallizes from Methanel. in yellow crystals from m.p. <B> 126 </B> 'to <B> 127' </B> and colors and #prints Acotateei-cle in yellow tones by Vorvorvoründer Liehteahtheit <I> example:
</I> <B> 18.5 </B> parts of l # Chl # o # r-, 2 # -nitro-4-eyaubenzol are mixed with about 120 parts of alcohol and 20 parts of aniline for several hours. heated to boiling under reflux cooling. When it is held, the condensation product formed separates out in yellow crystals.
