molecular formula: Mg(CH3COO)2·4H2O
CAS: 16674-78-5
Appearance:
Colorless crystal
Properties:
Colorless single inclined crystals, density of 1.454 g/cm (no water content density for 1.42 g/cm), soluble in water and ethanol, aqueous show neuter or weak acidity, 80 ℃ when crystallization water soluble. In humid air ChaoXie, the strong sulfuric acid dryers weathering, 100 ℃ when dehydration. Used as an analytical reagent preparation sodium acetate, 5-dimethyl magnesium to determine material in the sodium content. Magnesium carbonate with acetic acid reaction, the enrichment, exhalation acetic acid magnesium crystals.
Use:
Used for catalyst, feed additives and cosmetics and so on. Also used as an analytical reagent preparation sodium acetate, 5-dimethyl magnesium to determine material in the sodium content.
