摘　　要：对碱式碳酸铜制备工艺进行了研究,在实验中,探讨了原料种类及配比、反应温度、加料方式等对反应的影响,提出一种制备碱式碳酸铜的大学无机化学实验方法。结果表明:当选用当硝酸铜与碳酸钠为原料,且两者摩尔比为1.0:1.2,反应温度为70℃,采用一次加料,产品收率可以达到96.3%。通过实验,可使学生得到初步的科研和能力训练,以培养学生独立设计实验的能力。The technology of producing copper sulphate was studied.In the experiment,the effects of raw material type and ratio,reaction temperature and feeding method on the reaction were discussed,and an experimental method of inorganic chemistry for preparing basic copper carbonate was proposed.The results showed that the optimum reaction conditions were as follows:reaction temperature was 70℃,the ratio of Na_(2)CO_(3)/Cu(NO_(3))_(2) was 1.2,charging of once for all,the yield of copper sulphate reached 96.3%under the optimum conditions.Through experiments,students can get preliminary research and ability training to cultivate students'ability of designing experiments independently.
