use | organic synthesis intermediate. Used as a raw material for organic synthesis Used for mildew prevention, sterilization, and moth prevention |
Production method | Stir cinnamaldehyde and glacial acetic acid intensely, and add bromine to react under cooling. Then add anhydrous potassium carbonate, heat and reflux the reactants for half an hour, cool, and precipitate crude products. The crude product is dissolved in ethanol and recrystallized to obtain a finished product with a yield of about 80%. |
