Molecular formula : C6H18O24P6
MW : No. 83-902245-7-7 660.04
nature : light yellow - hazel Slurry liquid, often calcium and magnesium salts exist in plant species and sprouting rice bran . The relative density of 1.58. Soluble in water, ethanol and acetone, almost insoluble in ether, benzene and chloroform. The aqueous solution pH : 1.3% when the concentration of 0.40,0.7% to 1.7,0.13 when 2.26,0.013 to 3.20%. Phytic acid with 12 acid, was strongly acidic, with a white metal chelate synthesis insoluble salts, such as 1g can be chelated iron 500mg. Heating break down, the higher the concentration of the more stable.
Preparation : widespread in the natural world, but hardly a separate free states. Generally in calcium, magnesium or potassium salt (6 Rockies alcohol phosphate calcium and magnesium) and protein complexes in the form of widespread plants, E its regular presence in seeds, grains, berries, rice bran. The method of goods reported many. For wheat bran or rice bran as raw material, by acid soaking after filtration with lime and sodium hydroxide neutralization, precipitation, and then ion-exchange resin acidification exchange, vacuum concentration, discoloration and filter, in products. It also has been through six Central alcohol and inorganic phosphate chemical synthesis, or by Phytin raw materials used for removal of metal ions. May corn from the activated sludge extraction.
purposes : the goods mainly for food additives and pharmaceutical raw materials. Canned prevent the formation of crystalline magnesium ammonium phosphate (MgNH4OP4 6H2O), the so-called Struvite preventing agent, tin and other metal to prevent the dissolution of the anti-browning agents and agent; For soybean paste, soy sauce, pickled products for the growing taste and color, to prevent bleaching agent; Oil antioxidant; PH regulator, the buffer; wasps head vegetables, cattle Burdock, pencil and other agricultural products to the preservative; chestnut, pear and other fruit canning anti-browning agents, pasta preservatives; the quality of fish processing improver; anti-clotting agent; vitamin B2, C, E, etc. stabilizers, sake, wine, brandy, etc. the anti-liquor agents, anti - phage infection agent; fermentation accelerator. Based on China's GB - 2760-88, and can be used right yes preservation, and residues should not exceed 20ppm. In addition, the industry can also be used in anti-rust agents, dishwashing liquid, explosion agents, antistatic agents, paints, significantly King agent, rare earth analysis reagents. Especially in liquid cyanide plating on the application to phytic acid or sodium cyanide phytate substitute for metal surface treatment, very eye-catching.
