|Section2= |Section7= }} Acetanilide〔.〕 is an odourless solid chemical of leaf or flake-like appearance. It is also known as N-phenylacetamide, acetanil, or acetanilid, and was formerly known by the trade name Antifebrin. ==Preparation and properties== Acetanilide can be produced by reacting acetic anhydride with aniline: :C6H5NH2 + (CH3CO)2O → C6H5NHCOCH3 + CH3COOH The preparation used to be a traditional experiment in introductory organic chemistry lab classes,〔See, e.g., ; : the latter preparation includes the reduction of nitrobenzene to aniline.〕 but it has now been widely replaced by the preparation of either paracetamol or aspirin, both of which teach the same practical techniques (especially recrystallization of the product) but which avoid the use of aniline, a suspected carcinogen. Acetanilide is slightly soluble in water, and stable under most conditions.〔 Pure crystals are plate shaped and colorless to white. 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「Acetanilide」の詳細全文を読む スポンサード リンク
