Description

  

  Verfahren zur Herstellung eines     Ogyarylsulfons.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     Oxyarylsul-          fons,    dadurch gekennzeichnet, dass man     4-          Chlornaplithyl-l-phenylsulfon    mit einem alka  lisch wirkenden Mittel erhitzt.  



  Das so erhaltene     4-Oxynaphthyl-l-phenyl-          sulfon    ist ein farbloser Körper vom Schmelz  punkt 107   C. Es soll als Zwischenprodukt  zur Herstellung von Farbstoffen, Heilmitteln,  Textil- und     Gerbereihilfsmitteln    sowie von  synthetischen Harzen Verwendung finden.  



  <I>Beispiel:</I>  40 Teile     4-Chlornaphthyl-l-phenylsulfon     werden mit 40 Teilen     Ätzkali    in etwa 400  Teilen Wasser im     Autoklaven    10 Stunden  auf etwa 200   C erhitzt. Es entsteht eine  Lösung, die beim Ansäuern das     4-Oxynaph-          thyl-l-phenylsulfon    vom     Schmelzpunkt   <B>107'</B> C  gibt.  



  Das als Ausgangskörper dienende     4-Chlor-          naphthyl-l-phenylsulfon    kann man zum Bei-    spiel durch Umsetzen von     Diazobenzolchlorid     mit     4-Chlor-l-thionaphthol    nach Ziegler (Be  richte der Deutschen Chemischen Gesellschaft,  Band 23, Seite 2469) und Oxydation des so  gebildeten     Thioäthers    mit Wasserstoffsuper  oxyd erhalten.



  Process for the preparation of an ogyaryl sulfone. The present patent relates to a process for the production of an oxyarylsulphon, characterized in that 4-chloronaplithyl-1-phenylsulphone is heated with an alkaline agent.



  The 4-oxynaphthyl-1-phenylsulfone obtained in this way is a colorless body with a melting point of 107 C. It is said to be used as an intermediate in the manufacture of dyes, medicinal products, textile and tanning aids and synthetic resins.



  <I> Example: </I> 40 parts of 4-chloronaphthyl-1-phenylsulfone are heated with 40 parts of caustic potash in about 400 parts of water in an autoclave at about 200 ° C. for 10 hours. The result is a solution which, when acidified, gives 4-oxynaphthyl-1-phenylsulfone with a melting point of <B> 107 '</B> C.



  The 4-chloronaphthyl-l-phenylsulfone used as the starting body can be prepared, for example, by reacting diazobenzene chloride with 4-chloro-l-thionaphthol according to Ziegler (reports from the German Chemical Society, Volume 23, page 2469) and oxidizing the thus obtained thioether with hydrogen peroxide.
