Safety Information
Cadmium chloride Usage And Synthesis
  • DescriptionCadmium chloride is a cadium halide consisting of cadmium and chlorine. It is well soluble in water, methanol and ethanol. It can be used in photography, in dyeing, electroplating fabric printing and calico printing and for precipitating sulfide. It can be used for the manufacture of cadium sulfide, organocadium compound of the type R2Cd. It is manufactured through the reaction between anhydrous chlorine and hydrogen chloride gas with heated cadmium metal. It can also be made through the reaction between hydrochloric acid with cadmium oxide. However, it is a hazard to the environment, and should be limited for spread.
  • UsesCadmium chloride (CdCl2), a soluble crystal, is formed when cadmium metal is treated with hydrochloric acid (Cd + 2HCl → CdCl2 + H2). CdCl2 is used in dyeing and printing textiles, in electroplating baths, in photography, and as the ingredient for cadmium yellow in artists’ oil paint.

  • DescriptionCadmium chloride is a colourless and odourless crystal. It is used for the preparation of cadmium sulphide, used as ‘cadmium yellow’, a brilliant-yellow pigment, which is stable to heat and sulphide fumes. Cadmium chloride has a high solubility in water and is a non-combustible solid, but the dust can be a moderate fire hazard when exposed to heat or flame or when reacted with oxidising agents. It is incompatible with bromine trifluoride, potassium oxidisers, zinc, selenium, tellurium, and hydrogen azide.
  • Chemical PropertiesCadmium chloride is a colorless, odorless, crystalline solid, or powder.
  • Chemical PropertiesMilky White free flowing crystalline powder
  • Physical propertiesColorless powder or crystal; hexagonal crystal system; hygroscopic; density 4.047 g/cm3; melts at 560°C; vaporizes at 960°C; highly soluble in water (140 g/100g at 20°C), also soluble in acetone; slightly soluble in alcohol; insoluble in ether.
  • UsesUsed in a preparation of highly luminescent CdTe nanocrystals.1
  • UsesCadmium Chloride is used in the preparation of the stable inorganic pigment cadmium sulfide (Cadmium Yellow). Cadmium Chloride treatment of thin film CDTe solar cells is used to produce high-efficienc y solar cells.. Cadmium Chloride is also used in the preparation of organocadmium compounds.
  • UsesPreparation of cadmium standard; analysis of sulfides; testing of pyridine bases.
  • UsesMade by the action of hydrochloric acid on cadmium and crystallization. The small white crystals are soluble in alcohol and water. Cadmium chloride was used to make collodionchloride printing-out emulsions, also known as leptographic or aristotype papers.
  • Production MethodsCadmium chloride is manufactured in reaction of cadmium metal, carbonate, sulfide, oxide, or hydroxide with hydrochloric acid, followed by evaporation; it forms hydrated salt. Commercial cadmium chloride is amixture of hydrates that approximates to dihydrates. The commercial grade available in the United States typically contains about 51% of cadmium. Liquid caddy contains 20.1% cadmium chloride.
  • PreparationCadmium chloride may be prepared by heating the metal with chlorine or hydrogen chloride gas. In the solution, it is formed by treating the metal or its salts, such as oxide, hydroxide, carbonate, or sulfide with hydrochloric acid:
    Cd + 2HCl → CdCl2 + H2
    CdO + 2HCl → CdCl2 + H2O
    CdCO3 + 2HCl → CdCl2+ H2O + CO2
    The solution is evaporated and crystallized to yield a hydrated salt. The hydrated salt yields anhydrous cadmium chloride upon heating under hydrogen chloride or when refluxed with thionyl chloride.
    Cadmium chloride also may be prepared by adding dry cadmium acetate to acetyl chloride in glacial acetic acid.
  • General DescriptionCadmium chloride is a white crystalline solid. Cadmium chloride is soluble in water. Cadmium chloride is noncombustible. The primary hazard of Cadmium chloride is that Cadmium chloride poses a threat to the environment. Immediate steps should be taken to limit its spread to the environment. Cadmium chloride is used in photography, in fabric printing, in chemical analysis, and in many other uses.
  • Air & Water ReactionsWater soluble.
  • Reactivity ProfileBromine trifluoride rapidly attacks the following salts: barium chloride, Cadmium chloride , calcium chloride, cesium chloride, lithium chloride, silver chloride, rubidium chloride, potassium bromide, potassium chloride, potassium iodide, rhodium tetrabromide, sodium bromide, sodium chloride, and sodium iodide [Mellor 2 Supp. 1:164, 165 1956].
  • Health HazardIngestion causes gastroenteric distress, pain, and prostration. Sensory disturbances, liver injury, and convulsions have been observed in severe intoxications.
  • Fire HazardLiterature sources indicate that Cadmium chloride is nonflammable.
  • Safety ProfileConfirmed human carcinogen with experimental carcinogenic and tumorigenic data. Poison by ingestion, inhalation, skin contact, intraperitoneal, subcutaneous, intravenous, and possibly other routes. Human systemic effects by ingestion: blood pressure, acute pulmonary edema, hypermotility, diarrhea. Experimental teratogenic and reproductive effects. Human mutation data reported. Reacts violently with BrF3 and K. When heated to decomposition it emits very toxic fumes of Cd and Cl-. See also CADMIUM COMPOUNDS and CHLORIDES.
  • Potential ExposureCadmium chloride is used in dyeing and printing of fabrics; in electronic component manufacture; in photography; used as a pesticide and in nonpasture turf fungicides.
  • ShippingUN2570 Cadmium compounds, Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.
  • Purification MethodsCrystallise it from water (1mL/g) by addition of EtOH and cooling. [Pray Inorg Synth V 153 1957, Wagenknecht & Juza in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II p 1093 1965.]
  • IncompatibilitiesIncompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, sulfur, selenium, potassium.
  • Waste DisposalIt is preferred to convert the salt to the nitrate, precipitate it with H2S, filter, wash and dry the precipitate and return it to the supplier.
