説明
Anhydrous Magnesium Acetate has the chemical formula Mg(CH
3COO)
2 and in its hydrous form, Magnesium Acetate Tetrahydrate, it has the chemical formula Mg(CH
3COO)
2.4H
2O. In this compound the magnesium metal has an oxidation state of 2
+.
Magnesium acetate is the magnesium salt of acetic acid.It is deliquescent and upon heating, it decomposes to form magnesium oxide.Magnesium acetate is commonly used as a source of magnesium or as a chemical reagent.
化学的特性
white deliquescent crystals
物理的性質
Magnesium acetate appears as white hygroscopic crystals. It smells like acetic acid and is soluble in water. When it is in an aqueous solution its pH can be considered to be neutral.
特性
In 1881 Charles Clamond invented the Clamond basket, one of the first effective gas mantles. The reagents used in this invention included magnesium acetate, magnesium hydroxide and water.
Magnesium acetate is commonly used as a source of magnesium or for the acetate ion in chemistry experiments. One example of this is when magnesium acetate and magnesium nitrate were both used to perform molecular dynamics simulations and surface tension measurements. In the experiment the authors found that the acetate had a stronger affinity for the surface compared to the nitrate ion and that the Mg
2+ strongly repelled away from the air/liquid interference. They also found that the Mg
2+ had a stronger tendency to bind with the acetate ion compared to the nitrate.
One of the more prevalent uses of magnesium acetate is in the mixture called calcium magnesium acetate (CMA). It is a mixture of calcium acetate and magnesium acetate. CMA is thought of as an environmentally friendly alternative deicer to NaCl and CaCl
2. CMA also acts as a powerful SO
2, NO
x, and toxic particulate emission control agent in coal combustion processes to reduce acid rain, and as an effective catalyst for the facilitation of coal combustion.
使用
Dye fixative in textile printing, deodorant, disinfectant, and antiseptic.
Magnesium acetate is used in chemistry and molecular biology as a reagent and a source of magnesium. Magnesium has a variety of biological roles in enzymology, cell membrane and wall structural integrity, muscle cell physiology, and nucleic acid structure.Magnesium is an essential co-factor in many enzymes, including deoxyribonuclease (DNase), the restriction enzymes EcoR I and EcoR V, and Ribonuclease H. Magnesium also stabilizes polymeric nucleic acids such as transfer RNA and ribozymes.
Magnesium acetate has been widely used in the crystallization of proteins. A protocol for the separation of MB and BB isoenzymes of creatine kinase and the LD1 isoenzyme of lactate dehydrogenase that involves elution with magnesium acetate has been published.

安全性
マグネシウム酢酸塩は比較的安全な物質とされていますが取り扱いには注意が必要です粉塵の吸入や皮膚目への接触を避けるために適切な保護具を着用することが推奨されますまたこの化合物は環境に対しても比較的安全ですが大量に水系に放出される場合は水生生物に対する潜在的な影響を考慮する必要があります
化学性质
マグネシウム酢酸塩はマグネシウムオキシドマグネシウム炭酸塩またはマグネシウム金属を酢酸と反応させることで製造されますこの過程では熱や圧力を調整することで製品の純度や結晶形を制御することが可能ですまたこの化合物は加熱することで分解し酢酸とマグネシウムオキシドに分かれます
安全性
Magnesium Acetate is a relatively safe compound to handle and has been given a health hazard rating of zero. However, it should always be handled with gloves and safety goggles. If it is gets in the eyes, the skin, ingested, or inhaled it will cause irritation in the respective areas: eyes, skin, gastrointestinal system, and lungs.
貯蔵
Due to the fact that it is very hygroscopic, it must be stored away from water. It is also incompatible with strong oxidizers and should not be mixed with them.
純化方法
Crystallise it from anhydrous acetic acid, then dry it under vacuum for 24hours at 100o. [Nencollas J Chem Soc 744 1956, Beilstein 2 IV 113.]
