氯化亚铜可以通过氯化铜溶液(CuCl2·H2O)的水解反应制备,即将氯化铜溶液加入HCL,再加热至90~110℃,直至溶液发生沸腾,待溶液清澈后,再进行冷却、沉淀,得到的沉淀物即为氯化亚铜结晶。 另外,我们也可以通过将铜溶液或铜粉混合氯化钠溶液,再加入少量稀硫酸,搅拌均匀,至溶液沸腾,冷却后沉淀,再经过过滤、洗涤、烘干,即可...
Crystallise the chloride from hot dilute aqueous HCl (0.6mL/g) by cooling in a CaCl2-ice bath. It is dehydrated by heating on a steambath under vacuum. It is deliquescent in moist air but efflorescent in dry air. The dihydrate is emerald green but blue when free from solvent. Concentrat...
Copper chloride is also known as cupric chloride, this substance was made by treating copper carbonate with hydrochloric acid. The greenish blue crystals are soluble in water, alcohol, and ether. This halide was added to printing-out and silver bromide emulsions for increased contrast. Uses Coppe...
CuCl2 is formed when copper(II) oxide, CuO, is treated with hydrochloric acid, HCl: CuO + 2HCI→CuCl2 + H2O. 2.6 Color/Form Yellow-brown 2.7 Corrosivity It is corrosive to aluminum. 2.8 Decomposition ... WHEN HEATED TO DECOMP ... THEY EVOLVE TOXIC FUMES OF /HYDROGEN CHLORIDE/. 2.9 ...
Copper(II) oxide is prepared synthetically by heating copper metal in air to about 800°C (1,500°F) or, more commonly, by heating copper(II) carbonate (CuCO3) or copper(II) nitrate [Cu(NO3)2] to red heat.Just under 0.007% of Earth's crust is comprised of copper. Around 46% of...
Accordingly, the present invention provides a process for producing cupric carbonate from waste liquid of PCB corrosion which comprises adding cupric oxide to waste liquid of PCB corrosion containing cupric chloride to remove free HCl, adding a neutrilizing agent such as sodium carbonate and sodium ...
