Abstract

The innovative laboratory procedure for the synthesis of copper(II) hydroxide in the form of the aqueous suspension was developed. The reaction mechanism consists of the reaction between copper(II) sulphate pentahydrate and sodium carbonate by successive ion exchange of carbonate ions with the hydroxide ones in a multistep process. Production of copper(II) carbonate and sodium sulphate by reacting of copper(II) sulphate with sodium carbonate was followed by addition of sodium hydroxide solution whereby the product, copper(II) hydroxide, was obtained by releasing an equimolar amount of sodium carbonate. It was determined that, the equimolar reaction of copper(II) sulphate and sodium hydroxide lead to the maximal reactants exploitation. Sodium phosphate, formed in the final process stage by addition of 10 % phosphoric acid solution, acted as a copper(II) hydroxide stabilizer. High yield of the product was obtained by optimizing the synthesis parameters: reaction time, molar ratio of reactants and the reaction temperature. The obtained product was formulated to obtain a commercial product, which is used as a fungicide and bactericide.

氢氧化铜（II）生产的创新环保技术

开发了以水悬浮液形式合成氢氧化铜（II）的创新实验室程序。反应机理包括五水硫酸铜（II）和碳酸钠之间的反应，通过在多步骤过程中碳酸根离子与氢氧根离子的连续离子交换。通过硫酸铜（II）与碳酸钠反应制备碳酸铜（II。研究表明，硫酸铜（II）与氢氧化钠的等摩尔反应能最大限度地利用反应物。在最后的工艺阶段，通过加入10%的磷酸溶液形成的磷酸钠起到了氢氧化铜（II）稳定剂的作用。通过优化合成参数：反应时间、反应物摩尔比和反应温度，获得了较高的产物收率。将获得的产品配制成商业产品，该产品用作杀菌剂和杀菌剂。
