【摘要】 以CuSO4和Na2CO3为原料,通过单因素实验和正交实验,研究加料顺序及方式、原料配比、反应温度、预热时间、pH等对产物品质及产量的影响。结果表明向CuSO4溶液中一次加入Na2CO3溶液,两者体积比为1.0∶1.2,反应温度75℃,产品品质较好,产率可以达到92%以上。更多还原

【Abstract】 Use CuSO4 and Na2CO3 as material,single factor experiment and the orthogonal test were adopted to study the effect of feeding order and methods,proportions of raw material,reaction temperature,warm-up time and pH on the product quality and output.The result show that the optimum conditions are as follows: the Na2CO3 solution were added into CuSO4 solution at one time,the ratio of v(CuSO4)/v(Na2CO3) is 1.0∶1.2,reaction temperature is 75 ℃,the product quality is high and the yield of basic cupric carbonate reaches 92 % under the optimum conditions.更多还原
