乙酰水杨酸(阿斯匹林)的制备

Preparation of acetyl-salicylic acid (Aspirin)

推荐一个大学基础有机化学实验——乙酰水杨酸（阿斯匹林）的制备，即在常压条件下以水杨酸和乙酸酐为原料·在浓硫酸为催化剂下通过酰基化试剂酯化反应，经加热、析滤、重结晶．最后得白色固体产品。产率可达85～90％。

A recommend for basic organic chemistry experiment in university the production of acetyl--salicylic （Aspirin）, which takes the salicylic acid and acetic oxidecon as raw material under the atmospheric pressure condition, takes the strong sulfuric acid as catalysis, through acetoxylation, heating, dialysising, filtering, heavy crystallization, the white solid product can be made finally. The productivity is almost 85-90%.
