磷酸二氢钠工厂直售 江苏发货

一、化学名称：磷酸二氢钠

二、分子式：NaH₂PO₄；NaH₂PO₄·H₂O；NaH₂PO₄·2H₂O

三、分子量：无水物：120.01；一水物：138.01；二水物：156.01

四、CAS：无水物：7558-80-7；一水物：10049-21-5；二水物：13472-35-0

五、性状：无色结晶或白色结晶性粉末。无臭。稍有潮解性。相对密度2.04。熔点60℃。易溶于水。不溶于乙醇。100℃以下加热，可溶于结晶水形成一水盐。加热至100℃失去结晶水而成无水物，继续加热则变为偏磷酸钠。

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：本品应贮存在干燥通风清洁的库房中，装载运输时要轻装轻放，防止包装破损，防止受潮、受热，运输过程中防止雨淋受潮，应与有毒物品隔离。

1、Chemical Name: Monosodium Phosphate

2、Molecular Formula: NaH₂PO₄ ; NaH₂PO₄·H₂O ; NaH₂PO₄·2H₂O

3、Molecular Weight: Anhydrous:120.01 ; Monohydrate:138.01 ; Dihydrate:156.01

4、CAS: Anhydrous:7558-80-7 ; Monohydrate:10049-21-5 ; Dihydrate:13472-35-0

5、Character: It is colorless column crystal, odorless, slightly deliquescence. The relative density is 2.04 and

melting point is 60℃. It is easily soluble in water but insoluble in ethanol. If heated below 100℃, it can

dissolve in its’ own crystal water and convert to monohydrate salt. When heated up to 100℃, it’ll lose

crystal water and change to anhydrous substances, which will become Sodium Metaphosphate if it

continues to be heated.

6、Usage: In food industry, it is used as buffering, character improving agent, emulsifier, nutrition supplement, antioxidant additive, brine penetrable agent, sugar clarifier, stabilizer, coagulant and fowl scalding agent. 

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.
