This heterocyclic amine consists of a six-membered ring containing five methylene bridges (--) and one amine bridge (-NH-). It is a colorless fuming liquid with an odor described as ammoniacal or pepper-like; the name comes from the genus name ''Piper'', which is the Latin word for pepper. Piperidine is a widely used building block and chemical reagent in the synthesis of organic compounds, including pharmaceuticals. == Production == Industrially, piperidine is produced by the hydrogenation of pyridine, usually over a molybdenum disulfide catalyst:〔Karsten Eller, Erhard Henkes, Roland Rossbacher, Hartmut Höke "Amines, Aliphatic" Ullmann's Encyclopedia of Industrial Chemistry 2002 Wiley-VCH. 〕 : C5H5N + 3 H2 → C5H10NH Pyridine can also be reduced to piperidine via a modified Birch reduction using sodium in ethanol. 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「Piperidine」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.
