  Process for the production of a condensation product.
EMI0001.0002
  
    The present <SEP> patent <SEP> refers to <SEP> see <SEP> on <SEP>
<tb> Process <SEP> for the <SEP> production <SEP> of a <SEP> condensate product, <SEP> marked with <SEP>, <SEP> da3
<tb> man <SEP> 1-chloro-2-nitrobenzene-4-ethylsulfone <SEP> with
<tb> p, aminophenol <SEP> condensed.
<tb>



  The. <SEP> <SEP> obtained <SEP> 4'-oxy-2-nitrodiph-enylamine-4-ethylsulfone <SEP> of <SEP> mp <SEP> 177 <SEP> <SEP> C <SEP> colors
<tb> Acetate silk <SEP> in <SEP> yellow-orange <SEP> shades <SEP> by <SEP> with ample <SEP> lightfastness.
EMI0001.0003
  
    <I> Example: </I> 5 parts of 1-chloro-2-nitrobenzene-4-ethylsulfone and 10 parts of p-aminophenol are refluxed for several hours with 150 parts of alcohol.

   At the
EMI0001.0013
  
    When <SEP> cools, <SEP> separates <SEP> the <SEP>, formed <SEP> 4'-oxy 2-nitrodiphenylamine-4-ethylsulfone <SEP> in crystalline form
<tb> off.
