Description

  

  Verfahren zur Herstellung eines     Aminoarylsulfones.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     Aminoaryl-          sulfones,    welches dadurch gekennzeichnet  ist, dass man 1     Mol        3.3'.4.4'-Tetrachlordi-          phenylsulfon    mit 2     Mol    Ammoniak umsetzt.  



  Das so erhaltene, bisher noch nicht be  kannte     3.3'-Dichlor-4.4'-diaminodipheiiylsul-          fon    schmilzt nach dem     Umkristallisieren    aus       Butylalkohol    bei<B>1800</B> C unter Zersetzung  und soll zur Herstellung von Farbstoffen und  Heilmitteln Verwendung finden.  



  <I>Beispiel:</I>       50-Teile        3.3'.4.4'-Tetrachlordiphenylsulfon     werden mit etwa 400 Teilen 25 %     igem    Am  moniak etwa 20 Stunden auf 2000 C erhitzt.  Nach dem Erkalten wird das Reaktionspro-         dukt    abgesaugt, mit kaltem Wasser gewa  schen und getrocknet.



  Process for the production of an aminoarylsulfone. The present patent relates to a process for the production of an aminoaryl sulfone, which is characterized in that 1 mole of 3.3'.4.4'-tetrachlorodiphenyl sulfone is reacted with 2 moles of ammonia.



  The previously unknown 3.3'-dichloro-4.4'-diaminodipheiiylsulfon obtained in this way melts after recrystallization from butyl alcohol at 1800 C with decomposition and is intended to be used for the production of dyes and medicinal products.



  <I> Example: </I> 50 parts of 3.3'.4.4'-tetrachlorodiphenyl sulfone are heated to 2000 ° C. with about 400 parts of 25% ammonia for about 20 hours. After cooling, the reaction product is filtered off with suction, washed with cold water and dried.
