| Physical and Chemical Properties | Relative density 1.542, melting point 153°C (dehydration), refractive index 1.493~1.509 Colorless translucent crystals or white granules, or white crystalline powder, often containing one molecule of water of crystallization, odorless, extremely sour taste, soluble in water and alcohol. Its calcium salt is more soluble in cold water than in hot water, a property often used to identify and separate citric acid. Controlling the appropriate temperature during crystallization can yield anhydrous citric acid. The aqueous solution is acidic. Slightly efflorescent in dry air, deliquescent in humid air. Decomposes above 175°C to release water and carbon dioxide. |
| Uses | Used as an experimental reagent, chromatographic analysis reagent, and biochemical reagent, also for the preparation of buffer solutions. Used in the food industry, especially as an acidulant, pH buffer, and as a preservative in combination with other compounds. In the detergent industry, it is an ideal substitute for phosphates. Boiler chemical cleaning acid washing agent, boiler chemical cleaning rinsing agent. Mainly used as a food acidulant, also for the preparation of pharmaceutical cooling agents, detergents, etc. |
