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!
prepared by heating a copper chloride solution with copper wire or copper powder.
used in electroplating industry, metallurgical industry, pharmaceutical and chemical industry, pesticide Engineering, battery industry, rubber industry and many other fields. In the chemical industry, it is used as a decolorizing agent, a desulfurizing agent, a releasing agent, a catalyst and a reducing agent; It is used as a gas absorbent in the dye industry; It is used as a raw material for anti-tuberculosis drugs and other drugs in the pharmaceutical field; It can also be used to manufacture pesticides, purification of molten metals and the manufacture of antifouling coatings.
toxic! It is strongly irritating to the skin, and the dust makes the skin itchy and blistering, stimulating the eyes to tears. Production operators should do a good job of protection, pay attention to the protection of the skin and respiratory organs. Should be stored in a cool, ventilated, dry, light-protected warehouse. The container must be sealed to prevent moisture. It shall not be stored and mixed with edible articles and oxidants. During transport to prevent rain and sun. When there is a fire, it can be suppressed by water, sand and various kinds of fire extinguisher.
