1.Chemical name: Ammonium acetate
2.Molecular formula: CH3COONH4
3.Molecular weight:77.08
4.Cas:631-61-8
5.Character: It occurs as white triangular crystal with acetic acid smell. It's soluble in water and ethanol, But insoluble in .Aqueous solubiton is neutral.
6.Usage: It is used as analytical reagent, meat preservative and also used in pharmacy.The uses of ammonium acetate are as follows:
Solvent
• It is used as a solvent in organic synthesis. For example, in the preparation of some organic compounds, it can dissolve certain reagents or intermediates. In the synthesis of some complex organic molecules, it provides a suitable medium for the reaction to proceed. It can help to stabilize the transition states of the reaction, thereby facilitating the formation of the desired products.
• It is also used in the purification of some substances. In the purification of certain organic dyes, it can dissolve impurities while leaving the desired dye molecules relatively undissolved. This allows for the separation and purification of the dyes through techniques like crystallization.
Buffer
• Ammonium acetate can act as a buffer in chemical reactions. It helps to maintain a relatively constant pH during the reaction process. In biochemical experiments, such as enzyme - catalyzed reactions, it can be used to create a buffer environment. Enzymes usually have an optimal pH range for their activity. Ammonium acetate can help to keep the pH within this optimal range, ensuring that the enzyme can function properly and the reaction can proceed at an appropriate rate.
Precipitating agent
• In analytical chemistry, it is used as a precipitating agent. For example, when analyzing certain metal ions in a solution, it can react with the metal ions to form insoluble metal acetates. These metal acetates can then be precipitated out of the solution. The precipitate can be collected, filtered, and weighed or further analyzed to determine the concentration of the metal ions in the original solution.
7.Packing:It is packed with polyethylene bag as inner layber, and a compound plastic woven bag as outer layer.
The net weight of each bag is 25kg
8.Storage adn 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.
