Description
Verfahren zur Herstellung eines Aryloaynaphtylketons. <B>Es</B> wurde gefunden, .dass man ein Aryl- oxynaphty lketon herstellen kann, wenn man auf 1-Oxynaphthalin-2-carbonsäure, mit oder ohne Zusatz von Verdünnungs- bezw. Kon densationsmitteln, aber unter Ausschluss von Alkalien, 2,4-Diclilorbenzotrichlorid einwir ken lässt.
Die so gewonnene 1-(2' . 4'-Dichlor- phenyl)- l#.eton-4-oxynaphtyl - 3 - carbonsäure bildet weisse Nadeln, die bei 201 ' unter Zer setzung schmelzen und sich in Ätzalkalien und in konzentrierter Schwefelsäure mit gel ber Farbe lösen.
Beispiel: 26,4 Teile 2,4-Dichlorbenzotrichlorid und <B>18,8</B> Teile 1-Oxynaphtalin-2-carbonsäure wer den bei Zimmertemperatur in 100 Teile kon zentrierte Schwefelsäure eingetragen und so lange zusammen gerührt, bis sich keine Salz säure mehr entwickelt. Hierauf giesst man in Wasser, filtriert die ausgeschiedene 1-(2' . 4' I)ieliloiThenyl)-heton-4-oxynaphtyl-3=carbon- Aure ab und reinigt sie durch Umkristalli- sieren ihres Natriumsalzes.
Process for the production of an aryloaynaphthyl ketone. It has been found that an aryl oxynaphthalene ketone can be produced if one uses 1-oxynaphthalene-2-carboxylic acid, with or without the addition of diluent or. 2,4-diclilobenzotrichloride can act as condensation agents, but with the exclusion of alkalis.
The 1- (2 '. 4'-dichlorophenyl) - l # .eton-4-oxynaphthyl - 3 - carboxylic acid obtained in this way forms white needles which melt at 201' with decomposition and are incorporated into caustic alkalis and concentrated sulfuric acid dissolve yellow over color.
Example: 26.4 parts of 2,4-dichlorobenzotrichloride 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 none Hydrochloric acid more developed. It is then poured into water, the precipitated 1- (2 '. 4' I) ieliloiThenyl) -hetone-4-oxynaphthyl-3-carbonic acid is filtered off and purified by recrystallizing its sodium salt.
