摘要:

设计了一个以水杨酸和乙酸酐为原料,以HZSM-5分子筛为催化剂,在室温或加热条件下高效合成乙酰水杨酸的半微量有机化学实验。与经典实验方法相比,新实验具有反应易于操作、产率高、污染小等优点,更符合绿色化学教学理念。

Abstract:

A semi-microscale organic chemistry experiment for the efficient synthesis of acetylsalicylic acid is designed, and the synthesis starts from salicylic acid and acetic anhydride with HZSM-5 as the catalyst at room temperature or heating conditions. Compared with the classical experimental method, the new experiment possesses the advantages of easy operation, high product yield and low pollution, which is more in line with the educational concepts of green chemistry.

Key words: Acetylsalicylic acid, HZSM-5 zeolite, Green chemistry
