硫酸亚铁   FERROUS SULFATE

 

一、化学名:硫酸亚铁

二、分子式:七水合物:FeSO4·7H2O ;干燥品:FeSO4·nH2O  

三、分子量:七水合物:278.03

四、CAS七水合物:7782-63-0干燥品7720-78-7

五、性状七水合物:蓝绿色结晶或颗粒。无臭,略带咸味,有收敛性。在干燥空气中会风化,在潮湿空气中易氧化成棕黄色碱式硫酸铁。易溶于水,不溶于乙醇。

干燥品:灰白色至米色粉末。有涩味。主要由FeSO4·H2O组成,并含少量的FeSO4·4H2O。缓慢溶于冷水(26.6g/100mL, 20℃),加热则迅速溶解。不溶于乙醇。几乎不溶于50%硫酸。

六、用途:营养增补剂(铁质强化剂)、果蔬发色剂。

七、包装:内衬聚乙烯塑料袋,外套复合塑料编织袋,每袋净重25kg

1Chemical Name: Ferrous Sulfate

2Molecular Formula : FeSO4·7H2O, FeSO4·nH2O

3Molecular Weight: Heptahydrate :278.03

4CAS: Heptahydrate: 7782-63-0; Dried: 7720-78-7

5Character: Heptahydrate: It’s blue-green crystals or granules, odorless with astringency. In dry air, it’s efflorescent. In moist air, it oxidizes readily to form a brown-yellow, basic ferric sulfate. It’s soluble in water, insoluble in ethanol.

6Usage: It is used as nutritional supplement(iron fortifier) and fruit and vegetable colorant.

7Packing: 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.

8Storage 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.
