Basic Information
English name: Citri Acid Anhydrous, citric acid anhydrous bp, citric acid anhydrous
MF: C6H8O7
MW: 192.1
2 Properties
Colorless translucent crystals or white granules or white crystalline powder, often containing molecule crystal water, odorless, very sour taste, soluble in water, alcohol and ether. Calcium salt easily soluble in hot water than in cold water, the nature of the citric acid used to identify and isolate. Suitable crystallization temperature control obtained anhydrous citric acid. Acidic aqueous solution. In dry air, slight weathering, deliquescence in moist air. Above 175 ℃ decomposition of water and carbon dioxide release.
Properties: The relative density of 1.542, melting point 153 ℃ (dehydration), the refractive index of 1.493 ~ 1.509, the critical temperature of the solution crystallization 36.6 ℃ (36.6 ℃ above the crystallization of anhydrous citric acid, the following 36.6 ℃ crystallization of citric acid monohydrate).
3 Uses
