电化学沉积法制备阿司匹林铜

Electro-Chemical Deposition Method to Prepare Copper Aspirin

以市售阿司匹林药片和铜片(牺牲阳极)为原料,利用电化学沉积法制备了标题化合物,并通过傅立叶变换红外光谱、X-射线衍射及单晶X-射线衍射对其进行表征.讨论了溶液浓度、初始pH、施加电压等条件对产物的影响,确定了最佳合成条件.该法反应装置简单、能避免副产物的产生,产物纯度高,而且是一种绿色合成法.

The crystals of the title compounds were prepared by electro-chemical deposition with aspirin tablets and copper piece as precursors,and were characterized by FT-IR,powder X-ray diffraction and single crystal X-ray diffraction respectively.The effects of factors like the initial concentration of aspirin solution,initial pH value on the formation of copper aspirin were also discussed,and the optimum reaction condition was established.The results reveal that electro-chemical deposition is performed with simple apparatus,can avoid effectively the formation of by-products due to using the copper as precursor to provide copper ions source,and is a green synthesis method to produce copper aspirin,in which no harmful by-products are presented.
