| Use | 2-hydroxyacetophenone can be used for the preparation of benzoylformic acid, which is an intermediate for the preparation of pharmaceuticals and pesticides, by complexing with metal elements, it is found that it can be used as a sensitizer for fluorescent materials and a catalyst for organic oxidation reactions, which has attracted more attention. |
| preparation | Add 20mmol of 48% hydrobromic acid at room temperature to a ML three-necked flask with 20mmol of styrene and ml of water, 200mmol 30% hydrogen peroxide was slowly added dropwise, controlled dropwise addition time was 30min, stirred at room temperature for 30min, heated to 80 ℃, and reacted for 10H. The organic phase and the aqueous phase were separated by standing. The organic phase containing 2-bromoacetophenone was added to a reactor containing 150ml of water , hydrolysis was completed under microwave acceleration, and the organic phase and the aqueous phase were allowed to stand to separate to obtain a 2-hydroxyacetophenone solution. |
