Description

  

  Verfahren zur Herstellung eines     Aminosulfons.       Es wurde gefunden, dass man ein     Amino-          sulfon    - das     1-Aminobenzol-2.4-di-n-butyl-          disulfon    erhält, wenn man     1-Chlorbenzol-          2.4-di-n-butyldisulfon    unter Druck mit wäs  serigem Ammoniak erhitzt. Das     1-Amino-          benzol-2.4-di-n-butyldisulfon    bildet ein wert  volles, bekanntes     Zwischenprodukt    zur Her=       stellung    von     Farbstoffen.     



  <I>Beispiel:</I>  30 Teile     1-Chlorbenzol-2.4-di-n-butyldi-          sulfon    werden zusammen mit 150 Teilen  24     o/oigem    Ammoniak und 100 Teilen Alkohol  in einem geschlossenen Gefäss während 10    bis 20 Stunden auf 130-135 o erhitzt.  Durch     Abdestillieren    des Alkohols erhält  man des     1-Aminobenzol    - 2 . 4-     di-    n -     butyldi-          sulfon,    das man, wenn nötig, durch Kri  stallisieren aus Alkohol reinigen kann.



  Process for the preparation of an aminosulfone. It has been found that an amino sulfone - 1-aminobenzene-2,4-di-n-butyl disulfone, is obtained when 1-chlorobenzene-2,4-di-n-butyl disulfone is heated under pressure with aqueous ammonia. 1-Aminobenzene-2,4-di-n-butyl disulfone is a valuable, well-known intermediate product for the production of dyes.



  <I> Example: </I> 30 parts of 1-chlorobenzene-2,4-di-n-butyldisulfone together with 150 parts of 24% ammonia and 100 parts of alcohol are heated to 130% in a closed vessel for 10 to 20 hours. 135o heated. The 1-aminobenzene-2 is obtained by distilling off the alcohol. 4-di- n - butyl disulfone, which, if necessary, can be purified by crystallizing it from alcohol.
