EspañolProduct overview
Sodium acetate is a kind of organic matter.
Sodium acetate trihydrate is white crystal with a relative density of 1.45 and a melting point of 58℃.
It is weathered in dry air, loses its crystalline water at 120℃ and decomposes at higher temperature.
Anhydrous sodium acetate is colorless transparent crystal, melting point 324℃.
Soluble in water.
Appearance:
Sodium acetate typically appears as a white, crystalline solid or powder.
Solubility:
It is highly soluble in water, with a solubility of approximately 1 g in 1.5 mL of water at room temperature.
Applications
In terms of metal content determination, sodium acetate is used for determination of lead, zinc, aluminum, iron, cobalt, antimony, nickel and tin. Complex stabilizer. Auxiliary agent of acetylation, buffer, desiccant, mordant.
In food industry, sodium acetate is used as buffering agent, flavouring agent, flavouring agent and ph regulator.
In rubber industry, sodium acetate is used as the sulfur external regulation of neoprene coking antiscorching agent, the dosage of general quality of 0.5. It can also be used as a crosslinking agent for animal glue.
