醋酸镁(乙酸镁)

醋酸镁   MAGNESIUM ACETATE

 

一、化学名:醋酸镁

二、分子式:C4H6O4Mg·4H2O

三、分子量:214.46

四、CAS16674-78-5

五、性状:无色单斜晶体,易潮解。溶于水,水溶液通常为中性或弱酸性。80℃时溶于结晶水中。湿空气中潮解,在浓硫酸干燥器中风化,100℃时脱水。。可由碳酸镁与乙酸反应制得。该品剧毒,遇明火、高热可燃。其粉体与空气可形成爆炸性混合物, 当达到一定浓度时, 遇火星会发生爆炸。受高热分解放出有毒的气体。

六、用途:用于饲料添加剂和化妆品;制备醋酸铀酰镁,用以测定钠;用于医药、工业、脱臭、杀菌、防腐剂、纺织品染色、曙红染色、苯胺黑的固定等用途。

七、包装:内衬聚乙烯塑料袋,外套复合塑料编织袋包装,每袋净重25kg。

八、贮存与运输:储存于阴凉、干燥、通风良好的库房。远离火种、热源。防止阳光直射。包装密封。应与氧化剂等分开存放,切忌混储。配备相应品种和数量的消防器材。储区应备有合适的材料收容泄漏物。

MAGNESIUM ACETATE

 

Chemical Name: Magnesium Acetate

Molecular Formula: C4H6O4Mg·4H2O

Molecular Weight: 214.46

4.CAS16674-78-5

5.CharacterIt occurs as mono-clinic crystal, easily deliquescent. It is easily soluble in water, the aqueous solution is neutral or weak acidic. It dissolves in crystal water at 80℃. It will be deliquescent in the moist air, it effloresces in concentrated sulfuric acid dryer, dehydration at 100°C. It is produced by Magnesium carbonate and Acetic acid. The product is highly toxic, and it is easily ignited by fire and heat. Its powder and air can form an explosive mixture. When it reaches a certain concentration, it will explode in the event of spark. It will be liberated toxic gases by high temperature.

6.Usage: It can be used for feed additives and cosmetics; Preparation of magnesium uranyl acetate, for the measurement of sodium; For pharmaceutical, industrial, deodorization, sterilization, preservatives, textile dyeing, blush stain, aniline black and other uses.

Packing:It is packed with polyethylene bag as inner layer, and a compound plastic woven bag as outer layer. The net weight of each bag is 25kg.

Storage and Transport: It should be stored in a dry and ventilative warehouse, kept away from heat, fire and direct sunlight. Package sealed and should be stored separately from oxidants, avoid store together. It also should be equippedwith an appropriate variety and quantity of fire fighting apparatus. Storage areas should be equipped with suitable materials for containment and leakage.
