Description
Verfahren zur Herstellung eines Aryloxynaphtylketons. Es wurde gefunden, dass man ein Aryloxy- naphtylketon herstellen kann, wenn man auf 1.-Oxynaphtalin-2-sulfosäure, mit oder ohne Zusatz von Verdünnungs- bezw. Kondensa tionsmitteln, aber unter Ausschluss von Al kalien, Benzotrichlorid einwirken lässt. Die so gewonnene 1.-Phenylkeion-4-oxynaphtyl-3- sulfosä.ure bildet ein weisses Pulver, welches sich in Ätzalkalien und in konzentrierter Schwefelsäure mit gelber Farbe löst.
<I>Beispiel:</I> 1.9,5 Teile Benzotrichlorid und 22.4 Teile 1. - Oxynaphtalin - 2 - sulfosäure werden bei Zimmertemperatur in 100 Teile konzentrierte Schwefelsäure eingetragen und so lange zu sammen gerührt, bis sich keine Salzsäure mehr entwickelt. Hierauf giesst man in Wasser. filtriert die ausgeschiedene 1-Phenyl-keton-4- oxyna,phtyl-3-sulfosäure ab und reinigt sie durch Umkristallisieren ihres Natriumsalzes.
Process for the preparation of an aryloxynaphthyl ketone. It has been found that an aryloxy naphthyl ketone can be produced if one responds to 1.-oxynaphthalene-2-sulfonic acid, with or without the addition of diluent or. Condensation agents, but with the exclusion of alkalis, allows benzotrichloride to act. The 1.-phenyl-4-oxynaphthyl-3-sulfonic acid obtained in this way forms a white powder which dissolves in caustic alkalis and concentrated sulfuric acid with a yellow color.
<I> Example: </I> 1.9.5 parts of benzotrichloride and 22.4 parts of 1. - oxynaphthalene - 2 - sulfonic acid are added to 100 parts of concentrated sulfuric acid at room temperature and stirred together until hydrochloric acid no longer develops. Then you pour in water. the precipitated 1-phenyl-ketone-4-oxyna, phtyl-3-sulfonic acid is filtered off and purified by recrystallizing its sodium salt.
