Use | is used as an analytical reagent. Mice were injected intravenously with an LD50 of 18mg/kg. used for printing and dyeing, also used as analytical reagent |
production method | is derived from the Co-heating of magnesium nitrate and acetic acid. Magnesium nitrate was heated together with anhydrous acetic acid. After the reaction was terminated, the solution was boiled for another 20min. After long-time storage, anhydrous magnesium acetate was precipitated. Suction filtration, washing with a small amount of absolute ethanol, then washing with ether, in a vacuum drying oven, drying at 60 °c. The crystals contain free acetic acid and should be dried for a long time until constant weight. It is also advisable that the magnesium acetate tetrahydrate is heated to a constant weight at 134 ° C. To obtain anhydrous magnesium acetate. |
