1、Chemical Name: Potassium Acetate
2、Molecular Formula : C2H3KO2
3、Molecular Weight: 98.14
5、Character: It is white crystalline powder. It’s easily deliquescent and tastes salty. PH value of 1mol/L aqueous solution is 7.0-9.0. Relative density（d425） is 1.570. Melting point is 292℃. It’s highly soluble in water (235g/100mL, 20℃; 492g/100mL, 62℃), ethanol (33g/100mL) and methanol (24.24g/100mL, 15℃), but insoluble in ether.
6、Usage: It is used as buffering agent, neutralizer, preservative and color fixative to
protect natural colors of animals and plants.
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.
