Description

  

  Verfahren zur Herstellung eines     Aryloxynaphtyll@etons.       Es wurde gefunden, dass ein     Aryloxy-          naplitylketon,    die     2-Phenylketon-l-oxynaph-          tyl-4-sulfosäure    in     guter    Ausbeute entsteht.,       wenn    man auf     1- xynaphtalin-4-sulfosäure          Benzotrichlorid    in     Gegenwart    von Alkalien  einwirken lässt.  



  Die so erhaltene     2-Phenylketon-l-oxy-          na.phtyl-4-sulfosäure    ist identisch mit der  jenigen, die nach dem Verfahren des Patentes  Nr.     1.00357    erhalten     wird.     



  <I>Beispiel: .</I>  246 Teile     1-oxynaphtalin-4-sulfosaures     Natrium werden     in    einer Mischung von<B>65</B>  Teilen 30     %iger    Natronlauge und 10 Teilen  Wasser gelöst und hierauf unter Rühren bei  70   nach und nach mit 220 Teilen     Benzo-          trichlorid    versetzt. Man rührt weiter bei 70  ,  bis alles     Trichlorid    verschwunden ist, fällt    die gebildete     2-Phenylketon-l-oxyDaphtyl-4-          sulfosäure    durch Ansäuern aus. Sie wird  durch     Umlösen    ihres     Natriumsalzes    gereinigt.

    Die     Aryloxynaphtylketone    der Patente Nr.  l00355, l00358, 100360 und 100361 können  in ähnlicher Weise hergestellt werden.



  Process for the production of an aryloxynaphtyll @ etons. It has been found that an aryloxynaphthalene ketone, 2-phenylketone-1-oxynaphthyl-4-sulfonic acid, is produced in good yield when benzotrichloride is allowed to act on 1-xynaphthalene-4-sulfonic acid in the presence of alkalis.



  The 2-phenylketone-1-oxy- na.phtyl-4-sulfonic acid obtained in this way is identical to that obtained by the process of patent no. 1.00357.



  <I> Example:. </I> 246 parts of 1-oxynaphthalene-4-sulfonic acid sodium are dissolved in a mixture of <B> 65 </B> parts of 30% sodium hydroxide solution and 10 parts of water and then added at 70 ° with stirring and then mixed with 220 parts of benzotrichloride. The mixture is stirred further at 70, until all the trichloride has disappeared, the 2-phenylketone-1-oxyDaphthyl-4-sulfonic acid formed precipitates out by acidification. It is purified by dissolving its sodium salt.

    The aryloxynaphthyl ketones of Patent Nos. 100355, 100358, 100360 and 100361 can be prepared in a similar manner.
