Open Data Verified Data
White cubic crystal or white powder. Relative density 4. 14; Melting point 430 ℃; Boiling point 1490 ℃. Slightly soluble in water, soluble in concentrated hydrochloric acid and ammonia to form a complex, insoluble in ethanol. Stable in dry air, moisture-prone to blue to brown. Molten iron gray, open air rapid oxidation to basic salt, green. It turned brown in light. In hot water, the rapid hydrolysis of copper oxide hydrate is red, and the reaction with strong acid is slow, and the carbon monoxide can be absorbed to form a complex (CuC1.CO-H2 0). Toxic!

| production method | copper wire air oxidation method the waste copper wire is added into the reactor to interact with a certain concentration of salt-hydrochloric acid solution, the oxidation was carried out at 60-70 ° C. By slowly passing air until the hydrochloric acid content in the reaction solution reached 10-15g/L. After static clarification, the upper cuprous chloride-sodium chloride clear solution is hydrolyzed to form cuprous chloride precipitate, which is filtered, washed with hydrochloric acid and ethanol, and dried at 60-80 ° C. To obtain cuprous chloride finished product. Its 2Cu 2HCl 2NaCl{[O]}→ 2Na[CuCl2] H2ONa[CuCl2][H2O]→ CuCl NaCl copper Ash hydrochloric acid method its process flow is basically the same as copper wire air oxidation method. The copper sulfate method adds copper sulfate and salt to the reactor for double decomposition reaction to generate copper chloride and sodium sulfate, filters to remove sodium sulfate, and adds sodium sulfite to the filtrate for reduction reaction to generate cuprous chloride precipitate and sodium chloride, the sodium chloride was removed by filtration, washed with ethanol, and dried at 60-80 °c to obtain a finished cuprous chloride. Its CuSO4 2NaCl → CuCl2 na2so42 cuc12 Na2SO3 → 2CuCl 2NaCl SO3 sulfur trioxide generated in the process of reduction reaction, with sodium sulfate aqueous solution absorption. |
