摘　　要：通过实验定量研究了Cu4（OH）6SO4与Cu（OH）2相互转化的特点及纯净Cu（OH）2制备的条件。研究结果表明,Cu4（OH）6SO4与Cu（OH）2之间能够相互转化,且转化相对缓慢;提高CuSO4浓度有利于Cu（OH）2向Cu4（OH）6SO4转化,提高NaOH浓度有利于Cu4（OH）6SO4向Cu（OH）2转化;纯净Cu（OH）2的制备方法为CuSO4溶液滴加到NaOH溶液中,且NaOH过量15%以上。This paper quantitatively studied the characteristics of transformation between basic copper sulfate and copper hydroxide and conditions for preparation of pure copper hydroxide.The results showed that basic copper sulfate and copper hydroxide could be transformed into each other slowly,increasing the concentration of copper sulfate was conducive to the transformation to basic copper sulfate,while increasing the concentration of sodium hydroxide was conducive to the transformation to copper hydroxide,and the pure copper hydroxide could be prepared by adding copper sulfate solution dropwise to sodium hydroxide solution which was in excess of fifteen percent above.
