Basic Information
Product Name: Phytic acid
CAS Number: 83-86-3
Alias: Inositol hexaphosphate, IP6, Myo-inositol hexakisphosphoric acid
Molecular Formula: C?H??O??P?
Molecular Weight: 660.04
IUPAC Name: (1R,2R,3S,4S,5R,6S)-cyclohexane-1,2,3,4,5,6-hexayl hexakis(dihydrogen phosphate)
Structural Information
- Structure Type: Natural organic polyphosphoric acid, cyclic hexaphosphate of myo-inositol
- Structural Features: Six phosphate groups attached to cyclohexane ring; multiple dissociable acidic hydroxyl groups, strong chelating capacity for metal ions (Fe3?, Cu2?, Zn2?, Ca2?); excellent antioxidant, anti-rust and corrosion inhibition performance
Physical & Chemical Properties
- Appearance: Colorless to pale yellow viscous aqueous liquid (commercial product is 50%~70% water solution); pure solid is white crystal
- Odor: Slight sour odor
- Melting Point (pure solid): 180℃ (decomposes)
- Density (50% aqueous solution, 20℃): ~1.33 g/cm3
- Solubility: Miscible with water, dilute alcohol; insoluble in acetone, ether, benzene, mineral oil
- Stability: Stable in weak acid environment; easy to hydrolyze under strong acid, high temperature or enzyme to generate lower inositol phosphates; reacts with metal ions to form insoluble phytate precipitates; compatible with most polar chemicals, corrosive to carbon steel
Synthesis & Applications
Production Method
Extraction from rice bran, corn germ and wheat bran with dilute acid, decolorization, ion exchange desalting, concentration to obtain liquid phytic acid.
Main Applications
- Metal surface treatment: Metal anti-rust passivation agent, replacement of phosphating solution, corrosion inhibitor for steel, copper, aluminum
- Food industry: Antioxidant, color stabilizer, metal ion chelator for edible oil, canned food, beverage
- Cosmetic raw material: Antioxidant, skin brightening ingredient, inhibits melanin formation by chelating metal catalytic ions
