Description
Verfahren zur Herstellung eines Aryloxynaphtyll@etons. Es wurde gefunden, dass ein Aryloxy- naplitylketon, die 2-Phenylketon-l-oxynaph- tyl-4-sulfosäure in guter Ausbeute entsteht., wenn man auf 1- xynaphtalin-4-sulfosäure Benzotrichlorid in Gegenwart von Alkalien einwirken lässt.
Die so erhaltene 2-Phenylketon-l-oxy- na.phtyl-4-sulfosäure ist identisch mit der jenigen, die nach dem Verfahren des Patentes Nr. 1.00357 erhalten wird.
<I>Beispiel: .</I> 246 Teile 1-oxynaphtalin-4-sulfosaures Natrium werden in einer Mischung von<B>65</B> Teilen 30 %iger Natronlauge und 10 Teilen Wasser gelöst und hierauf unter Rühren bei 70 nach und nach mit 220 Teilen Benzo- trichlorid versetzt. Man rührt weiter bei 70 , bis alles Trichlorid verschwunden ist, fällt die gebildete 2-Phenylketon-l-oxyDaphtyl-4- sulfosäure durch Ansäuern aus. Sie wird durch Umlösen ihres Natriumsalzes gereinigt.
Die Aryloxynaphtylketone der Patente Nr. l00355, l00358, 100360 und 100361 können in ähnlicher Weise hergestellt werden.
Process for the production of an aryloxynaphtyll @ etons. It has been found that an aryloxynaphthalene ketone, 2-phenylketone-1-oxynaphthyl-4-sulfonic acid, is produced in good yield when benzotrichloride is allowed to act on 1-xynaphthalene-4-sulfonic acid in the presence of alkalis.
The 2-phenylketone-1-oxy- na.phtyl-4-sulfonic acid obtained in this way is identical to that obtained by the process of patent no. 1.00357.
<I> Example:. </I> 246 parts of 1-oxynaphthalene-4-sulfonic acid sodium are dissolved in a mixture of <B> 65 </B> parts of 30% sodium hydroxide solution and 10 parts of water and then added at 70 ° with stirring and then mixed with 220 parts of benzotrichloride. The mixture is stirred further at 70, until all the trichloride has disappeared, the 2-phenylketone-1-oxyDaphthyl-4-sulfonic acid formed precipitates out by acidification. It is purified by dissolving its sodium salt.
The aryloxynaphthyl ketones of Patent Nos. 100355, 100358, 100360 and 100361 can be prepared in a similar manner.
