Description
Verfahren zur Herstellung eines Aryloxynaphtylketons. <B>Es</B> wurde gefunden, dass man ein Aryloxy- n.aphtylketon herstellen kann, wenn man auf 1-Oxynaphtalin-2-carbonsäure, mit oder ohne Zusatz von Verdünnungs- bezw. Kondensa tionsmitteln, aber unter Ausschluss von Alka- lien, 1-Chlor-2-naphthotrichlorid einwirken lässt.
Die so gewonnene 1-Chlor-2- 1'-dinaph- tylketon-4'-oxy - 3'-carbonsäure bildet weisse Nadeln, die bei 213 unter Zersetzung schmel zen und sich in Atzalkalien und in konzen trierter Schwefelsäure mit gelber Farbe lösen. <I>Beispiel:</I> 28 Teile 1-Chlor-2-naphthotrichlorid und <B>18,8</B> Teile 1 - Oxynaphtalin - 2 - carbonsäure werden bei Zimmertemperatur in 100 Teile konzentrierter Schwefelsäure eingetragen und solange zusammen gerührt, bis sich keine Salz säure mehr entwickelt.
Hierauf giesst man in Wasser, filtriert die ausgeschiedene 1- Chlor-2 . 1'-,dinaphtylketon-4'-oxy-3 - carbon- säure ab und reinigt sie durch Umkristalli- sieren ihres Natriumsalzes.
Process for the preparation of an aryloxynaphthyl ketone. <B> It </B> has been found that an aryloxy n.aphtyl ketone can be produced if one responds to 1-oxynaphthalene-2-carboxylic acid, with or without the addition of diluent or. Condensation agents, but with the exclusion of alkali, allows 1-chloro-2-naphthotrichloride to act.
The 1-chloro-2- 1'-dinaphthylketone-4'-oxy-3'-carboxylic acid obtained in this way forms white needles which melt at 213 with decomposition and dissolve in caustic alkalis and in concentrated sulfuric acid with a yellow color. <I> Example: </I> 28 parts of 1-chloro-2-naphthotrichloride and <B> 18.8 </B> parts of 1 - oxynaphthalene - 2 - carboxylic acid are added to 100 parts of concentrated sulfuric acid at room temperature and stirred together for as long until no more hydrochloric acid develops.
It is then poured into water and the 1-chloro-2 which has separated out is filtered off. 1 '-, dinaphthyl ketone-4'-oxy-3 - carboxylic acid and purifies it by recrystallizing its sodium salt.
