용도
개요
Cadmium 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.
용도
Cadmium 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.
일반 설명
Cadmium 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.
제조 및 합성 방법
제조 방법
Cadmium 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 + H2CdO + 2HCl → CdCl2 + H2OCdCO3 + 2HCl → CdCl2+ H2O + CO2The 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.
생산 방법
Cadmium 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.
