| titleOfInvention | Preparation method of N-benzylphthalimide |
| abstract | The invention provides a preparation method of N-benzylphthalimide, which comprises the following steps of reacting phthalic acid and benzylamine serving as raw materials, N, N-dimethylformamide or dimethylacetamide serving as a solvent, triethylamine/trinitromethane eutectic liquid serving as a catalyst under the conditions of normal temperature and normal pressure. After the reaction is finished, adding a proper amount of toluene, cooling to 0-5 ℃, and filtering to obtain the target compound N-benzylphthalimide. The preparation method has the advantages of simple reaction steps, high yield, high product purity, mild conditions and easy industrial production. |
