Method for producing 5-bromo-2-pentanone |
| abstract |
(57) [Summary] [Objective] 5-Bromo-, which is useful as a synthetic intermediate for pharmaceuticals and agricultural chemicals. It is to provide an industrially excellent production method of 2-pentanone. [Structure] 5-Bromo-2-pentanone is a mixture of α-acetyl-γ-butyrolactone and hydrobromic acid in the presence of sulfuric acid. It can be synthesized by reacting in a poorly water-soluble solvent. |
