硫酸亞鐵 FERROUS SULFATE
一、化學(xué)名:硫酸亞鐵
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、性狀:七水合物:藍(lán)綠色結(jié)晶或顆粒。無(wú)臭,略帶咸味,有收斂性。在干燥空氣中會(huì)風(fēng)化,在潮濕空氣中易氧化成棕黃色堿式硫酸鐵。易溶于水,不溶于乙醇。
干燥品:灰白色至米色粉末。有澀味。主要由FeSO4·H2O組成,并含少量的FeSO4·4H2O。緩慢溶于冷水(26.6g/100mL, 20℃),加熱則迅速溶解。不溶于乙醇。幾乎不溶于50%硫酸。
六、用途:營(yíng)養(yǎng)增補(bǔ)劑(鐵質(zhì)強(qiáng)化劑)、果蔬發(fā)色劑。
七、包裝:內(nèi)襯聚乙烯塑料袋,外套復(fù)合塑料編織袋,每袋凈重25kg。
八、貯存與運(yùn)輸:本品應(yīng)貯存在干燥通風(fēng)清潔的庫(kù)房中,裝載運(yùn)輸時(shí)要輕裝輕放,防止包裝破損,防止受潮、受熱,運(yùn)輸過(guò)程中防止雨淋受潮,應(yīng)與有毒物品隔離。
1、Chemical Name: Ferrous Sulfate
2、Molecular Formula : FeSO4·7H2O, FeSO4·nH2O
3、Molecular Weight: Heptahydrate :278.03
4、CAS: Heptahydrate: 7782-63-0; Dried: 7720-78-7
5、Character: 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.
6、Usage: It is used as nutritional supplement(iron fortifier) and fruit and vegetable colorant.
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.
