The oxidation of secondary alcohols to ketones is an important oxidation reaction in organic chemistry. When a secondary alcohol is oxidised, it is converted to a ketone. The hydrogen from the hydroxyl group is lost along with the hydrogen bonded to the second carbon. The remaining oxygen then forms double bonds with the carbon. This leaves a ketone, as R1–COR2. Ketones cannot normally be oxidised any further because this would involve breaking a C–C bond, which requires too much energy.〔Burton, George et al. (2000). ''Salters Advanced Chemistry: Chemical Ideas (2nd ed.)''. Heinemann. ISBN 0-435-63120-9〕 The reaction can occur using a variety of oxidants. ==Potassium dichromate== A secondary alcohol can be oxidised into a ketone using acidified potassium dichromate and heating under reflux. The orange-red dichromate ion, Cr2O72−, is reduced to the green Cr3+ ion. This reaction was once used in an alcohol breath test. 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「Oxidation of secondary alcohols to ketones」の詳細全文を読む スポンサード リンク
