|Section2= |Section3= |Section4= }} Diacetone alcohol is a chemical compound with the formula CH3C(O)CH2C(OH)(CH3)2, sometimes called DAA. This liquid is a common synthetic intermediate used for the preparation of other compounds, and is also used as a solvent. It occurs naturally in Sleepy grass (''Achnatherum robustum''). ==Synthesis== First identified by Heintz,〔Heintz, Ann. 169, 114 (1873)〕 one standard laboratory preparation of DAA entails the Ba(OH)2-catalyzed condensation of two molecules of acetone. It undergoes dehydration to give the α,β-unsaturated ketone, mesityl oxide: Hydrogenation of mesityl oxide gives the industrial solvent, methyl isobutyl ketone ("MIBK"). : 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「diacetone alcohol」の詳細全文を読む スポンサード リンク
