Cadmium acetate - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| Use | Used as an analytical reagent |
| production method | 5g of cadmium nitrate tetrahydrate is added to 25mL of acetic anhydride, mixed evenly, heated, refluxed for 15min after intense reaction, cooled, and crystals precipitated. Suction filtration, washing with a small amount of acetic anhydride, and then washing with ether. Drying in a vacuum dryer with solid potassium hydroxide and concentrated sulfuric acid, with a yield of 3.6g. Cadmium acetate dihydrate can also be heated at 130 ℃ in vacuum to remove two molecules of crystal water to obtain cadmium acetate. |
