Sodium Phosphate Dibasic Anhydrous

Sodium Phosphate Dibasic Anhydrous (CAS：7558-79-4), with the chemical formula Na₂HPO₄, is an important inorganic salt compound that, with its unique physicochemical properties and a wide range of applications, has been used in a variety of industries such as chemistry, medicine, food, agriculture, environmental protection and laboratories. occupies a pivotal position. The purpose of this paper is to discuss the basic properties, preparation process, diversified applications, and safety and environmental considerations of Sodium Phosphate Dibasic Anhydrous from a more comprehensive point of view, in order to provide readers with a comprehensive and three-dimensional cognitive framework.

1.Basic Characteristics and Physical and Chemical Properties

Sodium Phosphate Dibasic Anhydrous usually exists in the form of Na₂HPO₄ or with different amounts of water of crystallization (e.g., Na₂HPO₄-2H₂O, Na₂HPO₄-7H₂O, Na₂HPO ₄-12H₂O) forms exist. The physical properties (e.g., color, density, melting point, solubility) of these forms vary with the water of crystallization content. For example, Sodium Phosphate Dibasic Anhydrous is a white powder with a density of about 1.52 g/cm³ and a melting point of about 243-245°C. It is very soluble in water and its aqueous solution is weakly alkaline. The pH of its aqueous solution depends on the concentration, but is usually maintained between 8.8 and 9.2, showing good buffering properties.

Sodium Phosphate Dibasic Anhydrous has good thermal stability, but decomposes to sodium pyrophosphate at high temperatures. In addition, it is hygroscopic and will gradually weather when exposed to air for a long period of time. These physicochemical properties form the basis for the performance of Sodium Phosphate Dibasic Anhydrous in various applications.

2.Diversified application fields

Sodium Phosphate Dibasic Anhydrous has a wide range of applications, penetrating into almost every aspect of social life.

Pharmaceuticals & Nutraceuticals: As a pharmaceutical excipient, Sodium Phosphate Dibasic Anhydrous is used to regulate the pH of medicines to ensure their stability and effectiveness in the body. In health care products, it is used as a mineral supplement to help maintain the acid-base balance in the body.

Food Processing: As a food additive, Sodium Phosphate Dibasic Anhydrous is used to improve the texture, taste and shelf life of foods. In baked goods, it can enhance the air holding capacity of dough and make bread more fluffy; in meat processing, it can improve the water retention and tenderness of meat.

Agriculture & Fertilizer: Sodium Phosphate Dibasic Anhydrous, as a kind of phosphorus fertilizer, is rich in phosphorus required by plants, which helps to improve soil fertility and promote crop growth. At the same time, it can also regulate soil pH, creating a suitable environment for crop growth.

Water Treatment and Environmental Protection: In the field of water treatment, Sodium Phosphate Dibasic Anhydrous is used to regulate the pH value of water, remove heavy metal ions, and as a scale inhibitor to prevent the scaling of pipes and equipment. In the field of environmental protection, it participates in the wastewater treatment process to help remove pollutants and protect water resources.

Laboratory and scientific research: Sodium Phosphate Dibasic Anhydrous is an important reagent in many biochemical experiments and chemical reactions, used in the preparation of buffer solutions, involved in enzymatic reactions and so on.

3. Safety and environmental considerations

Although Sodium Phosphate Dibasic Anhydrous shows great application value in many fields, its safety and environmental protection issues should not be ignored. Long-term exposure to high concentrations of Sodium Phosphate Dibasic Anhydrous dust or solution may cause irritation or injury to the skin, eyes and respiratory system. Therefore, during production, use and storage, it is important to strictly follow safety procedures and wear appropriate personal protective equipment.

In addition, the production and use of Sodium Phosphate Dibasic Anhydrous may generate wastewater, exhaust gas and solid waste, posing a potential threat to the environment. For this reason, effective pollution control measures, such as wastewater treatment, exhaust gas purification and waste recycling, should be taken to ensure that the production activities comply with the requirements of environmental regulations and achieve sustainable development.

With the progress of science and technology and the enhancement of environmental protection awareness, the preparation process of Sodium Phosphate Dibasic Anhydrous will be more green and efficient in the future, and the application fields will be further expanded and deepened, contributing to the sustainable development of human society.
