Aspirin Active Pharmaceutical Ingredient (API) Synthesis Practice Device
Aspirin, also known as acetylsalicylic acid, is a long-standing antipyretic and analgesic drug that has been in use for over a century. It has become one of the three classic drugs in the history of medicine and remains the most widely used antipyretic, analgesic, and anti-inflammatory drug worldwide today. Additionally, it serves as a standard preparation for comparing and evaluating other pharmaceuticals. The synthesis process of aspirin active pharmaceutical ingredients (API) involves multiple chemical engineering operation units; therefore, developing a teaching and practical training device for the synthesis and production of aspirin API holds significant practical importance for vocational colleges and higher education institutions.
