一、化學(xué)名：硫酸鈉

二、分子式：無水：Na₂SO₄；十水：Na₂SO₄·10H₂O

三、分子量：無水：142.04；十水：322.19

四、CAS：無水：7757-82-6；十水：7757-73-3

五、性狀：白色單斜晶系結(jié)晶或粉末，無臭。有苦咸味，又名無水芒硝。相對密度2.68，熔點(diǎn)884℃，溶于水，水溶液呈堿性，溶于甘油，不溶于乙醇。暴露于空氣中易吸濕成為含水硫酸鈉。高純度、顆粒細(xì)的無水硫酸鈉稱為元明粉。

六、用途：用作焦糖色素制造用劑、食用色素稀釋劑。

七、包裝：內(nèi)襯聚乙烯塑料袋，外套復(fù)合塑料編織袋包裝，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)輸過程中防止雨淋受潮，應(yīng)與有毒物品隔離。

1、Chemical Name:  Sodium  Sulfate

2、Molecular Formula :  Na₂SO4 (Anhydrous), Na₂SO₄·10H₂O(Decahydrate)

3、Molecular Weight: 142.04 (Anhydrous), 322.19(Decahydrate)

4、CAS: 7757-82-6(Anhydrous), 7757-73-3 (Decahydrate)

5、Character: It’s white monoclinic crystal or crystalline powder, odorless. It tastes bitter and salty. It’s also called anhydrous mirabilite. Relative density is 2.68. Melting point is 884℃. It’s soluble in water and glycerin, insoluble in ethanol. Aqueous solution is alkaline. When exposed to air, it’ll easily absorb moisture and turn into aqueous Sodium Sulfate. Fine Sodium Sulfate Decahydrate with high purity is called glauber salt.

6、Usage: It’s used as caramel pigment manufacturing agent and edible pigment diluents.

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.
