Citric
Acid Anhydrous , formula C6H8O7, is a colorless, translucent crystals or
white granules or white crystalline powder , often containing one molecule of
water of crystallization , odorless, very sour taste , soluble in water,
alcohol and ether. Suitable crystallization temperature control obtained
anhydrous citric acid . Acidic aqueous solution. In dry air, slight weathering
, deliquescence in moist air . Mainly for the food and beverage industry as a
sour agent , acidity regulator, flavoring agents and preservatives ,
preservative . Also the chemical industry, cosmetics industry and the industry
as a washing antioxidants, plasticizers , detergents.
Character
Colorless transparent crystals or white
particles, or white crystalline powder, often contain molecular crystal water,
odourless, taste very acid, soluble in water, alcohol and ether. The calcium
salt easy dissolve in cold water than hot water, and the properties of commonly
used to identify and separate citric acid. Crystallization in control the
temperature of the appropriate anhydrous citric acid can be obtained. Acidic
aqueous solution. Micro have to weathering in dry air, deliquescence in moist
air. More than 175 ℃ decomposition release water and carbon dioxide.
Physical and chemical properties: the
relative density 1.542, melting point 153 ℃ (water), the refractive index of 1.493 ~ 1.509, the solution
crystallization critical temperature 36.6 ℃, 36.6 ℃ above crystallization of anhydrous citric acid, crystallization of
citric acid monohydrate) below 36.6 ℃.
Use
Mainly used for food and beverage industry
as sour agent, acidity regulator, flavouring agent, preservative and
antistaling agent. Also in the chemical industry, cosmetics industry and
washing industry used as antioxidant, plasticizer and detergent
Storage
Avoid light, sealed, dry place storage
