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        3.4-Dicblorphenyläthyl-          sulfon    mit 1     lyIol    Ammoniak umsetzt.  



  Das so erhaltene, bisher noch nicht be  kannte     3-Chlor-4-aminophenyläthylsulfon     schmilzt nach dem     Umkristallisieren    aus       Äthylalkohol    bei 1230 C und soll zur Her  stellung von Farbstoffen und Heilmitteln  Verwendung finden.  



  <I>Beispiel:</I>  100 Teile     3.4-Dichlorphenyläthylsulfon     werden mit etwa     550    Teilen 17 0%igem  Ammoniak etwa 24 Stunden auf<B>1950</B> C  erhitzt. Nach dem Erkalten wird das Reak-         tionsprodukt    abgesaugt, mit kaltem Wasser  gewaschen 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 mol of 3,4-dicblorphenylethyl sulfone is reacted with 1 lyol of ammonia.



  The so obtained, previously unknown 3-chloro-4-aminophenylethylsulfone melts after recrystallization from ethyl alcohol at 1230 C and is to be used for the manufacture of dyes and medicines.



  <I> Example: </I> 100 parts of 3,4-dichlorophenylethylsulfone are heated to <B> 1950 </B> C for about 24 hours with about 550 parts of 17 0% ammonia. After cooling, the reaction product is filtered off with suction, washed with cold water and dried.
