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.
