|Section2= |Section7= }} Hexachlorocyclohexa-2,5-dien-1-one, sometimes informally called hexachlorophenol (HCP) is an organochlorine compound which can be prepared from phenol. Despite the informal name, the compound is not a phenol but is a ketone;〔S. Gali, C. Miravitlles and M. Font-Altaba "Hexachlorocyclohexa-2,5-dienone" Acta Cryst. 1975, volume B31, p. 2510-2512. .〕 the informal name is derived from its method of preparation which includes phenol as a reagent. ==Preparation== HCP is normally produced by electrophilic chlorination of phenol by chlorine gas in the presence of metal chloride catalyst, such as ferric chloride. It can also be produced by alkaline hydrolysis of chlorobenzenes at high temperature and pressure, by conversion of diazonium salts of chlorinated anilines, or by chlorination of phenolsulphonic acids and benzenesulphonic acids followed by removal of the sulphonic acid group. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hexachlorocyclohexa-2,5-dien-1-one」の詳細全文を読む スポンサード リンク
