无水碳酸钠

Sodium carbonate (anhydrous), with a purity of ≥99.9% trace metals basis, is a white powder/crystals, white powder that is highly hygroscopic in nature. It is commonly known as soda ash or calcined soda. It is widely used in various industries, including glass manufacturing, chemical synthesis, detergents, and water treatment. Sodium carbonate is thermally stable up to high temperatures, making it suitable for applications that require heat resistance, such as in ceramic and glass production. The compound has a basic pH when dissolved in water, which allows it to act as a buffering agent in various biochemical and analytical applications, helping to maintain stable pH levels.

Sodium carbonate is a key ingredient in the production of glass and ceramics. In research settings, it is used to formulate glass compositions and study the effects of different additives on glass properties, such as thermal expansion and chemical durability.Recent studies have explored the use of sodium carbonate in the production of sodium-ion batteries. Its role in the synthesis of sodium-based materials for energy storage applications highlights its significance in the development of sustainable energy solutions. In a recent study, Na₂CO₃ was added to the composite positive electrode of P2−Na₂/₃Fe₁/₂Mn₁/₂O₂ as a sacrificial salt, providing Na⁺ through the electrochemical oxidative decomposition of Na₂CO₃ during the initial charging process.[2] In materials science, sodium carbonate is utilized in the synthesis of various inorganic compounds, including metal carbonates and oxides. Its high purity is essential for producing compounds with consistent properties, which are critical for research in catalysis and materials development. For example,Na₂CO₃ and NaHCO₃ act as heterogeneous catalysts in biodiesel production. Sodium Carbonate (anhydrous) is a versatile reagent widely employed in organic synthesis. It acts as a catalyst in aldol condensation for the preparation of chalcone and azachalcone, serves as a base in Pd-catalyzed Suzuki coupling, and is equally effective in transition metal-free Suzuki reactions, enabling the formation of valuable biaryl compounds in aqueous systems with TBAB as a phase-transfer catalyst.
