| 应用领域 | Uses: Used as a chemical reagent and intermediate、[Hawley] Used as a reagent for resorcinol and thalline、[Merck Index]、Chemical reagent and intermediate、Methods of Manufacturing: Prepared by oxidation of 1-amino-2-naphthol with ferric chloride:...、by oxidation of naphthalene: Milas、US 2395638 (1946 to Research Corp.)、by bacterial dissimilation of naphthalene:...、from tetrachloro-o-benzoquinone...、1、2-Naphthoquinone is obtained in 80% yield when 2-naphthol is oxidized by air in the liquid phase with copper(I) chloride as catalyst. Slightly lower yields are obtained when periodic acid and dimethyl formamide、iodosobenzene、or benzene seleninic anhydride is used as oxidant. A 95% yield can、however、be obtained with tetramethyloxopiperidinium chloride at low temperature. The quinone can also be obtained by the oxidation of 1-amino-2-hydroxynaphthalene hydrochloride with iron(III) chloride in hydrochloric acid.、General Manufacturing Information: 1、2-Naphthalenedione: INACTIVE |
