화학적 성질 · 1건

Citric acid monohydrate occurs as colorless or translucent crystals or as a white crystalline, efflorescent powder. It is odorless and has a strong acidic taste. The crystal structure is orthorhombic. monohydrate crystals lose water of crystallization in dry air or when heated to about 40 to 50℃. Citric acid monohydrate softens at 75℃ and melts at approximately 100℃. It serves as a natural preservative and is commonly utilized to contribute an acidic or sour taste to foods and soft drinks.Citric acid monohydrate acts as a preservative and antioxidant. It is also used as an acidulant, flavoring agent and antistaling agent in fruit drinks, candy, cookies, biscuits, canned fruits, jams, and jellies. It differs from other forms of citric acid by having a moisture percentage ranging from 7.5-9.0.

Chemical: Citric acid, monohydrate
Chemical DangersThe solution in water is a weak acid. Attacks copper, zinc, aluminium and their alloys.
Physical DangersDust explosion possible if in powder or granular form, mixed with air.

용도Citric Acid Monohydrate is a tricarboxylic acid found in citrus fruits. Citric acid is used as an excipient in pharmaceutical preparations due to its antioxidant properties. It maintains the stability of active ingredients and is used as a preservative. It is also used as an acidulant to control pH and acts as an anticoagulant by chelating calcium in the blood. Additionally, Citric Acid Monohydrate is used as an acidulating, food additive, and synergist in antioxidant mixtures.

일반 설명Citric acid monohydrate is an organic acid. Its molar enthalpy of solution in water has been reported to be ΔsolHm (298.15K, m = 0.0203molkg-1) = (29061 ± 123)Jmol-1

제조 방법 · 1건

Currently, the industrial production process for citric acid monohydrate crystals involves several steps. First, the citric acid fermentation liquid is separated from the solid-liquid to obtain a citric acid clear liquid. Then, the clear liquid undergoes purification via the calcium salt method (hydrogen calcium method), acidolysis, and decolorization. This purified solution is then heated, concentrated, and crystallized to produce anhydrous citric acid. The mother liquor remaining from this process is then filtered by plate and frame and added to a crystallization cylinder to reach a supersaturated state through cooling and precipitating the crystal. Once the temperature reaches around 13 ℃, the mixture undergoes centrifugal separation, and the resulting wet crystal is then dried in a dryer. The separated mother liquor, after being filtered, decolorized, and concentrated, is added back to the crystallization cylinder to repeat the above steps a total of four to five times. Finally, the mother liquor is returned to the extraction workshop for re-purification via chromatographic separation.
