The Improvement and Exploration of the Prepared Experiment of the Basis Carbonate Copper in Inorganic Chemistry

探讨了无机化学实验中碱式碳酸铜制备的改进方法。采用CuSO4和Na2CO3为原料进行制备,确定了最佳实验条件为n CuSO4/n Na2CO3=1:1,T=60℃,终点溶液pH=8.5,静置48h,反加(硫酸铜溶液加入到碳酸钠溶液)。通过元素分析、红外光谱分析、X-RD等手段确定了该方法制备出了高纯度的碱式碳酸铜。

It is studied for the Improvement and exploration of the prepared experiment of the basis carbonate copper in inorganic chemistry. CuSO4 and Na2CO3 as raw material to prepare the Basis Carbonate Copper. The results show that the optimum reaction conditions are as follows ： reaction temperature is 60℃, the ratio of n CuSO4/n Na2 CO3 is 1 ： 1, and pH is about 8. 5, standing time is 48h, the approach is add -back （copper sulfate solution into sodium carbonate solution） . By elemental analysis, IR and X -RD, high purity basic copper carbonate is synthesized
