13933-17-0 - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| inorganic compound | cupric chloride, also known as Copper dichloride, is an inorganic compound with monoclinic yellow or tan crystal or crystalline powder, deliquescent, toxic, dry air stroke, in nature to the existence of copper chloride. Is a planar chain-like covalent compound, relative molecular mass 134.45, relative density 3.386(25 ° C), melting point 620 ° C, heated to 993 ° C when the decomposition of cuprous chloride, and the release of chlorine. Soluble in water (g/100g):0 ℃ 69.2, 10 ℃ 71.5, 20 ℃ 74.5, 25 ℃ 76.4, 30 ℃ 78.3, 40 ℃ 86.8, 89.4 at 50 ℃, 98.0 at 60 ℃, 100 at 110.5 ℃; Soluble in ethanol: 43.3 at 0 ℃, 50.0 at 20 ℃, 58.3 at 40 ℃, 70.8 at 60 ℃; soluble in methanol: 0 ℃ 56.5, 20 ℃ 58.6, 40 ℃ 61.8, 60 ℃ 66.4; Also soluble in ether, acetone, pyridine, liquid ammonia and sulfuric acid. Its thermal stability is not as good as cuprous chloride, but it is more stable than cuprous chloride in aqueous solution. Copper chloride aqueous solution is yellow green at high concentration, and Green at a slightly lower concentration. The medium concentration is blue, the dilute concentration is sky blue, and the heating is yellow brown. The yellow color is due to the formation of [CuCl4]2 coordination ions, and the blue color is due to the formation of [Cu(H2O)4]2 coordination ions, which are green when they coexist. Interaction with ammonia, the formation of a beautiful dark blue copper ammonia coordination ion [Cu(NH3)4]2, this coordination ion dissolved in acetic acid, the formation of copper acetate ammonia liquid, can be used as carbon monoxide absorbent. Copper chloride and strong alkali, the formation of light blue copper hydroxide. With reducing anions such as I-, CN-, etc., the formation of cuprous salt (or complex) precipitation, the relevant reaction formula is as follows: 2Cu2 4I-→ 2CuI I2 2Cu2 6CN-→ 2Cu(CN)2- (CN)2, also with sulfur dioxide, Sn2, copper, etc., reduction to cuprous chloride: 2CuCl2 2NaCl SO2 2H2O → 2CuCl 4HCl Na2SO4. In alkaline solution, copper chloride can be reduced to red cuprous chloride by glucose and other reducing agents. Using this feature, diabetes can be examined: 2CuCl2 2NaOH C6H12O6 → 2CuCl C6H12O7 2NaCl H2O. copper chloride can be used as a catalyst for many organic reactions (such as the chlorination of hydrocarbons), as a decolorizing agent and desulfurizing agent for petroleum products, as well as wood preservatives, mordant and disinfectant in textile printing and dyeing, feed additives and glass, ceramic pigments. |
| toxicity | cupric chloride is irritating to the skin, the dust irritates the eyes and causes corneal ulceration. Production personnel should wear work clothes, wearing covers, gloves and other labor protection articles, the production equipment is sealed, and the workshop is well ventilated. Take a shower after work. |
| Application | used as electroplating additive, chemical reaction catalyst, oil industry deodorization desulfurization and purification agent, printing and dyeing mordant, used as analytical reagents, catalysts and pesticides The electroplating industry is used as an additive to increase copper ions in electroplating baths. Used as glass, ceramic colorants, organic hydrogenation catalyst. Oil industry deodorization, desulfurization and purification agent. Mordant and dye colorant for printing and dyeing. Used for metal smelting, photographic plate as etchant, wood preservative. It is used as an additive for insecticides, water purification disinfectant and fish feed. used in pigment, wood preservation and other industries, and used as disinfectant, mordant, Catalyst organic and inorganic reaction catalyst, beam agent, insecticide, oil deodorization, desulfurization and purification agent. |
| production method | hydrochloric acid method a certain amount of copper oxide is gradually added to the reactor containing hydrochloric acid, the acid hydrolysis reaction was carried out by adding with stirring, and copper chloride was generated. When the pH value of the reaction solution is 2 and the concentration is 35~37 ° Bé, the reaction is completed, and the solution is clarified by standing, and sodium hypochlorite is added to the clear solution, divalent iron is oxidized to trivalent iron and removed by hydrolytic filtration. The filtrate was concentrated by evaporation, cooled to crystallize, centrifuged, and dried at 60~70 ℃ to prepare a copper chloride product, cuO 2HCl → CuCl2 H2O |
