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-Dichlorphenylmethylsulfon     mit 1     Mol    Ammoniak umsetzt.  



  Das so erhaltene, bisher noch nicht be  kannte,     3-Chlor-4-aminophenylmethylsulfon     schmilzt nach dem     Umkristallisieren    aus       Butylalkohol    bei<B>195-1960</B> C und soll zur  Herstellung von     Farbstoffen    und Heilmitteln  Verwendung finden.    <I>Beispiel:</I>    100 Teile     3.4-Dichlorphenyl-methylsulfon     werden mit etwa 500 Teilen 20      /aigem     Ammoniak etwa 20 Stunden unter Rühren  auf     195-200'   <B>0</B> erhitzt. Nach dem Erkalten    wird das     Reaktionsprodukt    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-dichlorophenylmethyl sulfone is reacted with 1 mol of ammonia.



  The 3-chloro-4-aminophenylmethylsulfone obtained in this way, previously unknown, melts after recrystallization from butyl alcohol at <B> 195-1960 </B> C and is intended to be used for the production of dyes and medicinal products. <I> Example: </I> 100 parts of 3,4-dichlorophenyl-methylsulfone are heated with about 500 parts of 20% ammonia for about 20 hours while stirring to 195-200 '0 </B>. After cooling, the reaction product is filtered off with suction, washed with cold water and dried.
