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.
