Description
Verfahren zur Herstellung eines Aryloxynaphtylketons. Es wurde gefunden, dass man ein Aryloxy- zia.plityllieton herstellen kann, wenn man auf 1-Oxyna.phtalin-2-carbonsäure, mit oder ohne Zusatz von Verdünnungs- bezw. Iiondensa- lionsmitt;eln, aber unter Ausschluss von Al- kalien, p-Clilorbenzotrichlorid einwirken lässt.
Die so gewonnene 1-(4'-.chlorphenyl)-heton-1- exynaplityl - 3 - carbonsäure bildet weisse Na- dfIn, welche bei<B>206</B> unter Zersetzung schmelzen und sich in Ätzalkalien und in konzentrierter Schwefelsäure mit gelber Farbe lösen.
<I>Beispiel:</I> 23 Teile p - Chlorbenzotrichlorid und 18,8 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-(4'- Chlorphenyl) - keton - 4-oxynaphtyl-3-carbon- säure ab und reinigt sie durch T3m.kristalli- sieren ihres Natriumsalzes.
Process for the preparation of an aryloxynaphthyl ketone. It has been found that an aryloxy zia.plityllieton can be produced if one resp. 1-Oxyna.phtalin-2-carboxylic acid, with or without the addition of diluent. Iion denaturants, but with the exclusion of alkalis, allows p-chlorobenzotrichloride to act.
The 1- (4 '-. Chlorophenyl) -hetone-1-exynaplityl-3-carboxylic acid obtained in this way forms white needles, which melt at <B> 206 </B> with decomposition and are incorporated into caustic alkalis and concentrated sulfuric acid yellow color.
<I> Example: </I> 23 parts of p - chlorobenzotrichloride and 18.8 parts of 1 - oxynaphthalene - 2 - carboxylic acid are added to 100 parts of concentrated sulfuric acid at room temperature and stirred together until no more hydrochloric acid develops.
It is then poured into water, the precipitated 1- (4'-chlorophenyl) -ketone-4-oxynaphthyl-3-carboxylic acid is filtered off and it is purified by crystallizing its sodium salt.
