粉唑醇二苯甲酮 - Reference Information
| freezing point | 22.0 to 28.0 ℃ |
| use | 2,4 '-difluorobenzone is an intermediate of the fungicide triazol (flutriafol). Used as an intermediate for the pesticide trioxazole |
| production method | its preparation method is to place fluorobenzene and anhydrous aluminum trichloride in a reaction kettle, add 2-fluorobenzoyl chloride dropwise at low temperature, stir at the same time, raise the temperature to reflux after dropwise addition, continue the reaction for 3 hours, cool to room temperature, add HCl dropwise, control pH = 3~4, delaminate, dry and distill the oil layer to obtain 2, 4-Difluorobenzophenone. |
