翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Isocyanate ： ウィキペディア英語版 Isocyanate Isocyanate is the functional group with the formula R–N=C=O. Organic compounds that contain an isocyanate group are referred to as isocyanates. An isocyanate that has two isocyanate groups is known as a di-isocyanate. Di-isocyanates are manufactured for reactions with polyols in the production of polyurethanes, a class of polymers. Isocyanates should not be confused with cyanate esters and isocyanides, whose behaviors are very different. The cyanate (cyanate ester) functional group (R–O–C≡N) is arranged opposite of the isocyanate group (R–N=C=O). Isocyanides have the connectivity R-N≡C, lacking the oxygen of the cyanate groups. ==Production== Isocyanates are produced by treating amines with phosgene: :RNH2 + COCl2 → RNCO + 2 HCl These reactions proceed via the intermediacy of a carbamoyl chloride (RNHC(O)Cl). Owing to the hazards associated with phosgene, the production of isocyanates requires special precautions.〔 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「Isocyanate」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.
