Description

  

  Verfahren zur Darstellung eines     Ozydiarylketons.       Vorliegendes Patent bezieht sich auf ein  Verfahren zur Darstellung eines     Oxydiaryl-          ketons,    dadurch- gekennzeichnet. dass man  2 .     3-Oxyna.phthoylchlorid    mit     Anisol    in Ge  genwart eines sauren Kondensationsmittels       lmn        densiert.     



  Das so erhaltene 2 .     3-Oxynaphthylanisyl-          keton    kristallisiert aus     Ligroin    in gelben.       glänzenden    Blättchen vom Schmelzpunkt  134 bis 134,5       (unkorr.).    Es soll als     Z:wi-          schenprodukt    zur Herstellung von Farbstof  fen dienen.  



  <I>Beispiel:</I>  210 Teile 2 .     3-Oxynaphthoylchlorid    wer  den in 1000 Teilen trockenem Schwefelkoh  lenstoff suspendiert, 120 Teile     Anisol    zu  gegeben und unter Rühren 220 Teile     Alu-          miniumehlorid    eingetragen und das Reak  tionsgemisch     etwa    drei Stunden auf etwa 45         erhitzt.        Das        Reaktionsprodukt        wird    sodann  in Wasser- eingetragen und der Schwefel-         kohlenstoff    durch Destillation entfernt, der  Rückstand     wird        abfiltriert,    nach dem Aus  ivaschen in heisser,

   verdünnter Natronlauge  aufgenommen,     filtriert    und aus der Lösung  das reine Produkt mit Kohlensäure gefällt.



  Process for the preparation of an ozydiaryl ketone. The present patent relates to a process for preparing an oxydiaryl ketone, characterized. that one 2. 3-Oxyna.phthoylchlorid condenses with anisole in the presence of an acidic condensing agent.



  The 2nd 3-Oxynaphthylanisyl ketone crystallizes from ligroin in yellow. shiny flakes with a melting point of 134 to 134.5 (uncorr.). It should serve as an intermediate product for the manufacture of dyes.



  <I> Example: </I> 210 parts 2. 3-Oxynaphthoyl chloride suspended in 1000 parts of dry carbon disulfide, 120 parts of anisole are added and 220 parts of aluminum chloride are added with stirring and the reaction mixture is heated to about 45 for about three hours. The reaction product is then added to water and the carbon disulfide is removed by distillation, the residue is filtered off, after washing in a hot,

   Dilute sodium hydroxide solution was added, filtered and the pure product precipitated from the solution with carbonic acid.

PATENTANSPRUCH: Verfahren zur Darstellung eines Oxydiaryl- ketons, dadurch gekennzeichnet. dass man 2. 3-Oxynaphthoylchlorid mit Anisol in Ge genwart eines sauren Kondensationsmittels kondensiert. Das so erhaltene 2. 3-Oxynaphthylanisyl- keton kristallisiert aus Ligroin in gelben, glänzenden Blättchen vom Schmelzpunkt 134 bis 134,5 (unkorr.). Es soll als Zwi schenprodukt zur Herstellung von Farbstof fen dienen. PATENT CLAIM: Process for the preparation of an oxydiaryl ketone, characterized. that 2. 3-oxynaphthoyl chloride is condensed with anisole in the presence of an acidic condensing agent. The 2,3-oxynaphthylanisyl ketone thus obtained crystallizes from ligroin in yellow, shiny flakes with a melting point of 134 to 134.5 (uncorrected). It should serve as an inter mediate product for the production of dyestuffs.
