    Product Overview

    Sodium acetate, known for its diverse applications, can exist in two forms: anhydrous crystals and crystalline hydrates. It has a specific density of approximately 1.45 g/cm^3. The anhydrous sodium acetate crystal appears as a white crystalline powder, while the hydrated form is characterized by colorless crystals. Its chemical identity is represented by the sodium acetate formula, CH3COONa. The molar mass of sodium acetate for the anhydrous type is about 82.03 g/mol. This compound, when dissolved as sodium acetate in water, exhibits excellent solubility, forming a clear solution. The pH of the solution, termed sodium acetate pH, generally leans towards a basic range, around 8-9. In many fields, sodium acetate is used not as a primary preservative but as a supplementary one, offering additional protection in combination with more potent preservatives.

    The main application of Sodium Acetate
    • In foods such as pickles, olives, and sauces, sodium acetate enhances flavor while acting as an acidity regulator to control pH.
    • As a livestock feed additive, sodium acetate improves digestion and nutrient absorption by optimizing the pH conditions in the stomach.
    • In pharmaceuticals, sodium acetate uses as an excipient to maintain optimal acidity to ensure drug stability and bioavailability.
    • In organic synthesis, sodium acetate acts as a mild source of acetic acid and a versatile catalyst for acetylation, alkylation, and condensation reactions to produce esters, ketones, and amides.
    • When added to concrete mixtures, sodium acetate accelerates the curing process through the crosslinking effect, improving compressive strength development and performance.
    • Sodium acetate ice melt, as an airport runway deicer, lowers the freezing point of water to melt ice and prevent ice and buildup on aircraft and road surfaces.
