    摘要： Pure halonaphthalic acid anhydrides are prepared from haloacenaphthenes by oxidation with nitric acid in a mixture of aliphatic carboxylic acid, water and nitric acid in the presence of vanadate, with or without further metal salts, at an elevated temperature and the reaction product is isolated and subjected to an oxidative after-treatment with hypochlorite in aqueous solution at a pH of from 9 to 12 at an elevated temperature. The products are intermediates for the manufacture of optical brighteners.
