乙酰水杨酸的合成实验催化剂的选择探讨

Discussion on Selection of Catalysts in the Experiment of Synthesizing Aspirin

有机化学实验室在做合成实验时,一般使用浓硫酸作为催化剂来合成,缺点是产率低,腐蚀性较大,对环境污染较重,不能回收利用,且易发生副反应。通过选用3种实验室常见化学品做催化剂,对实验结果、环境友好性、消耗等方面论证了硫酸氢钠作为合成乙酰水杨酸实验的催化剂的可行性。

During experiment of synthesizing Aspirin in organic chemistry laboratory,the strong sulfuric was often used as catalyst.The defect is low yield,high corrosive,pollution the environment,cannot recycling,and side reaction.In this paper,through selecting three laboratory common chemicals as catalysts,comparing experiment result,and environmental friendliness,consumption and so on,the results demonstrates the odium bisulfate as catalytic synthesis is feasible in the experiment.
