Product features of different forms of sodium acetate Product features of different forms of sodium acetate

Sodium acetate is mainly divided according to morphology: solid sodium acetate (powder or crystal), liquid sodium acetate. According to the product level, there are mainly food grades, pharmaceutical grades, industrial grades and other levels.

Sodium acetate, also known as sodium acetate, is an organic substance with the molecular formula CH3COONa and a molecular weight of 82.03. Sodium acetate trihydrate has the characteristics of white crystals, with a relative density of 1.45 and a melting point of 58 °C, weathering in dry air, losing crystalline water at 120 °C, and decomposing when the temperature is high; sodium acetate anhydrous is a colorless transparent crystal with a melting point of 324 °C. Easily soluble in water, it can be used as a buffer, mordant, for the determination of lead, copper, nickel-iron, media preparation, organic synthesis, film printing, etc.

Sodium acetate solution

Main indicators: content: content≥ 20%, 25%, 30% Appearance: clear and transparent liquid. Sensory: no irritating odor. Water insoluble substances: ≤0.006%

Main uses:

Treat municipal sewage and study the effects of mud age (SRT) and additional carbon sources (sodium acetate solution) on the effect of system nitrogen and phosphorus removal. Sodium acetate was used as a supplementary carbon source to domesticate the denitrification sludge, and then the pH increase during the denitrification process was controlled within the range of 0.5 using a buffer solution. Denitrifying bacteria can overabsorb CH3COONa, so when denitrification with CH3COONa as an applied carbon source, the COD value of the effluent can be maintained at a low level. At present, all cities and counties' sewage treatment needs to add sodium acetate as a carbon source if it wants to meet the emission level one standard.

Implementation standard: national standard / enterprise standard

Storage conditions: barrel sealed storage, avoid leakage, placed in a cool and dry place. Avoid incompatible items.

Solid sodium acetate trihydrate

Main indicators: content ≥ 58-60% Appearance: colorless or white transparent crystal. Melting point: 58°C. Water solubility: 762g/L (20°C)

Main uses: organic synthesis of esterifiers, medicine, printing and dyeing mordant dyes, buffers, chemical reagents

Storage conditions: the warehouse ventilation, low temperature and drying; separated from oxidants and acids

Sodium acetate without anhydrous water

Main indicators: content ≥ 58-60% Appearance: white or off-white powder. It can be weathered in the air and is flammable. Soluble in water and ether, slightly soluble in ethanol.

Main uses: buffer, flavoring agent, flavor enhancer, PH regulator

Storage conditions: In an airtight container and in a cool, dry, well-ventilated area. Avoid exposure to high temperatures and humidity.

Food grade sodium acetate

Appearance: White powder

In the food industry, sodium acetate is used as a preservative and pickling agent. Because salt helps foods maintain a specific pH, it stops the growth of harmful bacteria. In the pickling process, this chemical is used in large quantities, which can not only act as a buffer for food and microorganisms, but also improve the taste of food.
