定義
ChEBI: 2,6-dichlorophenol is a dichlorophenol with the chloro substituents at positions 2 and 6. It is used as a chemical intermediate for 2,4,6-trichlorophenol and in the production of dehydro-l-ascorbic acid.
-
製造方法
2,6-Dichlorophenol has been prepared by the chlorination of phenol with chlorine gas in the presence of nitrobenzene and fuming sulfuric acid, by the decomposition of the diazotate of 2,6-dichloro-4-aminophenol, and by the decarboxylation of 3,5-dichloro-4-hydroxybenzoic acid in quinoline or dimethylaniline.
