Quinizarin is an orange or red-brown crystalline powder. It is formally derived from anthraquinone by replacement of two hydrogen atoms by hydroxyl (OH) groups. It is one of ten dihydroxyanthraquinone isomers and occurs in small amounts (as a glycoside) in the root of the madder plant, ''Rubia tinctorum''. ==Production== Quinizarin is produced by the reaction of phthalic anhydride and 4-chlorophenol followed by hydrolysis of the chloride: :C6H4(CO)2O + ClC6H4OH → C6H4(CO)2C6H2(OH)Cl + H2O :C6H4(CO)2C6H2(OH)Cl + H2O → C6H4(CO)2C6H2(OH)2 + HCl It can also be prepared less efficiently from phthalic anhydride and hydroquinone. 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「1,4-Dihydroxyanthraquinone」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
