Description

  

  Verfahren zur Herstellung eines     Ogyarylsulfons.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Herstellung eines     Oxyarylsul-          fons,    dadurch gekennzeichnet, dass man ein       2-Halogendiphenylsulfon    mit einem alkalisch  wirkenden Mittel erhitzt.  



  Das     soerhaltene        2-Oxydiphenylsulfon    ist  ein farbloser Körper vom Schmelzpunkt 99  bis<B>100'</B> C. Es soll als Zwischenprodukt zur  Herstellung von Farbstoffen,     Heilmitteln,     Textil- und     Gerbereihilfsmztteln    sowie von  synthetischen Harzen Verwendung finden.  <I>Beispiel:</I>  In eine durch Auflösen von 250 Teilen       Kaliumhydroxyd    in 1400 Teilen Wasser be  reitete Lauge werden 211 Teile     2-Chlordi-          phenylsulfon        (Fp.        107-1,08     ), erhältlich  beispielsweise durch Kondensation von       2-Chlorbenzolsulfochlorid    mit Benzol, einge  tragen.

   Die     Mischung    wird im     Rührautokla-          ven    etwa     10,Stunden    auf 210-220   erhitzt.  Man erhält eine hellgefärbte Lösung des         Verschmelzunbgsproduktes,    die nach Filtra  tion am Rührwerk in überschüssige verdünnte       Salzsäure    eingetragen wird. In fast theoreti  scher     Ausbeute    fällt als weisser Niederschlag  das     2-Oxydiphenylsulfon    aus, das im Va  kuumgetrocknet und aus verdünntem Alko  hol umgelöst den Schmelzpunkt     99-100'    C  zeigt.



  Process for the preparation of an ogyaryl sulfone. The present patent relates to a process for the production of an oxyarylsulphone, characterized in that a 2-halodiphenylsulphone is heated with an alkaline agent.



  The 2-oxydiphenyl sulfone obtained in this way is a colorless body with a melting point of 99 to <B> 100 '</B> C. It is intended to be used as an intermediate product in the manufacture of dyes, medicinal products, textile and tannery auxiliaries and synthetic resins. <I> Example: </I> In an alkali prepared by dissolving 250 parts of potassium hydroxide in 1400 parts of water, 211 parts of 2-chlorodiphenyl sulfone (melting point 107-1.08), obtainable, for example, by condensation of 2-chlorobenzenesulfochloride, are added with benzene.

   The mixture is heated to 210-220 in a stirred autoclave for about 10 hours. A light-colored solution of the fusion product is obtained which, after filtration, is introduced into excess dilute hydrochloric acid on the stirrer. In almost theoretical yield, the 2-oxydiphenylsulfone precipitates out as a white precipitate;
