Sodium Phosphate Dibasic Anhydrous
Sodium Phosphate Dibasic Anhydrous, with the chemical formula Na₂HPO₄, is a common phosphate compound, usually in the form of anhydrous or crystalline hydrate, which is a white crystalline powder or granule at room temperature, soluble in water, and its aqueous solution is weakly alkaline, with a pH value of about 9.0-9.4. Its aqueous solution is weakly alkaline with a pH value of about 9.0-9.4, a property that makes it unique in many scenarios.
Chemically, Sodium Phosphate Dibasic Anhydrous has a certain buffering capacity. When mixed with Sodium Phosphate Dibasic Anhydrous in a certain ratio, it can form a phosphate buffer, which can effectively maintain the stability of the solution pH value, and this buffer system is widely used in biochemical experiments and industrial production. In addition, it can also react with metal ions to produce the corresponding phosphate precipitation, which makes it very useful in the fields of water treatment and metal processing.
Sodium Phosphate Dibasic Anhydrous is an important food additive in the food industry. In dairy processing, it can be used as an emulsifier to help the fat particles in milk evenly dispersed, to prevent the cream from layering, such as in the production of phylloxera cream, the addition of an appropriate amount of Sodium Phosphate Dibasic Anhydrous can make the cream texture delicate, stability enhancement, and prolong the preservation time. In the processing of meat products, it can improve the water retention and adhesion of meat, such as the production of luncheon meat, add 0.2%-0.4% of Sodium Phosphate Dibasic Anhydrous, can make the product elasticity and slicing has been significantly improved.
Sodium Phosphate Dibasic Anhydrous is also critical in pharmaceutical applications. In some oral drug formulations, it acts as a pH regulator to ensure an optimal environment for dissolution and absorption of the drug in the body. In infusion preparations, it is often used with other substances to form a buffer system to maintain the stability of the pH of the drug solution and ensure the safety of infusion. In addition, it also plays the role of regulating osmotic pressure in some topical disinfection products to reduce the irritation of skin and mucous membrane.
In agriculture, Sodium Phosphate Dibasic Anhydrous can be used as a fertilizer to provide crops with two nutrients, phosphorus and sodium, to promote the growth and development of crops, especially for crops with high phosphorus demand, such as oilseed rape and cotton.
In terms of environmental impact and sustainability, the production and use of Sodium Phosphate Dibasic Anhydrous needs to be concerned about the environment. During the production process, if not properly treated, the wastewater produced may contain high concentrations of phosphate, which can easily trigger eutrophication when discharged into water bodies, leading to algal blooms and disrupting the aquatic ecological balance. Therefore, manufacturers need to adopt advanced wastewater treatment technologies, such as biological dephosphorization, to reduce the content of phosphate in wastewater so that it meets the discharge standards.
In the use segment, over-application of fertilizers containing Sodium Phosphate Dibasic Anhydrous in agriculture may lead to the accumulation of phosphorus in the soil, which in turn enters water bodies through surface runoff and exacerbates eutrophication of water bodies. For this reason, the amount of fertilizer applied should be reasonably controlled, and precise fertilizer application techniques should be promoted to improve the utilization rate of fertilizer.
Meanwhile, the concept of sustainable development is also driving the transformation of Sodium Phosphate Dibasic Anhydrous related industries. Enterprises are actively developing green production processes to reduce energy consumption and pollutant emissions in the production process. For example, they are adopting a circular economy model to recycle the by-products generated during the production process and improve the resource utilization rate. It is also exploring alternative products to Sodium Phosphate Dibasic Anhydrous to reduce its dependence on it and minimize environmental impact at source.
