Physicochemical property
| Molecular weight: 163.94 g/mol | Appearance: white crystalline or powdery solid. |
| Odor: Odorless or slightly sulphide odor. | Density: 1.62 g/cm³ (dodecahydrate, 20°C). |
| Melting point: approx. 73.4°C (dodecahydrate decomposition). | Chemical Safety: Unrestricted goods |
| Solubility: Water: easily soluble in water, aqueous solution is strongly alkaline (pH about 12); Organic solvent: insoluble in ethanol, and other organic solvents. |
| Hydrolysis reaction: Fully ionized in water to form phosphate ions and sodium ions |
| Complexation: Form an insoluble precipitate with metal ions (e.g. Ca² +, Mg² +) for softening hard water. |
| Thermal stability: It decomposes when heated to high temperatures, forming sodium phosphate and oxygen. |
| Acid base: The aqueous solution is strongly basic and can react with acid to form phosphate. |
Potassium dihydrogen phosphate (KH₂PO₄) has a variety of
uses in the industrial field, mainly including the following:
1. Agriculture
Fertilizer: As a high-efficiency phosphorus and potassium compound fertilizer,
it is suitable for a variety of crops, especially in the flowering and fruiting period,
it can promote fruit expansion, color transformation, and improve crop stress resistance.
Foliar fertilizer: It is often used for foliar spraying to quickly supplement phosphorus
and potassium nutrients and enhance crop disease resistance and lodging resistance.
2. Food industry
Food additive: As a quality improver, leavening agent, fermentation aid, etc.,
used in baked goods, beverages, dairy products, etc., to adjust pH value and improve taste.
3. Pharmaceutical industry
Pharmaceutical raw materials: Used in the production of certain drugs,
such as drugs that supplement phosphorus and potassium, or as buffers to regulate the pH value of drugs.
4. Chemical industry
Buffer: used in chemical production to adjust the pH value of the reaction system,
commonly found in electroplating, dyes, detergents and other fields.
Flame retardant: As a flame retardant component, it is used in plastics, rubber
and other materials to improve its flame retardant performance.
5. Water treatment
Corrosion inhibitor: Used as a corrosion inhibitor in water treatment to prevent corrosion of pipes
and equipment, and to regulate the pH of water quality.
6.Step Lab
Chemical reagent: As a standard reagent for buffer solution,
used in biochemical experiments and molecular biology research.
