硫酸錳 MANGANESE SULFATE
一、化學名:硫酸錳
二、分子式:MnSO4·H2O
三、分子量:169.02
四、CAS:7785-87-7
五、性狀:淺粉紅色單斜晶系粗晶體。無臭。相對密度2.95。加熱到200℃以上時開始失去結晶水,約在280℃時大部分結晶水失去,至700℃時成無水鹽熔融物;800℃時開始分解,殘留黑色的不溶性Mn3O4,約在1150℃完全分解。易溶于水,不溶于乙醇。
六、用途:營養(yǎng)增補劑(錳強化劑)。
七、包裝:內襯聚乙烯塑料袋,外套復合塑料編織袋包裝,每袋凈重25kg。
八、貯存與運輸:本品應貯存在干燥通風清潔的庫房中,裝載運輸時要輕裝輕放,防止包裝破損,防止受潮、受熱,運輸過程中防止雨淋受潮,應與有毒物品隔離。

1、Chemical Name: Manganese Sulfate
2、Molecular Formula : MnSO4·H2O
3、Molecular Weight: 169.02
4、CAS: 7785-87-7
5、Character: It is pale pink monoclinic system coarse crystal, odorless. Relative density is 2.95. It starts to lose crystal water when heated to above 200℃. It almost loses all crystal water when above 280℃. And to 700℃, it changes to anhydrous melts. It starts to decompose when heated to 800℃ and black insoluble Mn3O4 is left. It completely decomposes at the temperature of 1150℃. It is freely soluble in water, but is insoluble in alcohol.
6、Usage: Nutritional Supplement (Manganese Fortifier)
7、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.
8、Storage and Transport: It should be stored in a dry and ventilative warehouse, kept away from heat and moisture during transportation, unloaded with care so as to avoid damage. Furthermore, it must be stored separately from poisonous substances.
