English Name : Ethylene diamine tetraacetic acid (EDTA) Molecular Fomula : C10H16N2O8 Molecular Weight : M=292.24 CASNo. : 60-00-4 Properties : white crystal powder melting point 240(decomposition) insoluble in cold water ,alcohol and general organic solvent, slightly soluble in hot water, but soluble in sodium hydroxide, sodium carbonate and ammonia solution. An agent for complexation, EDTA is mainly used for water treatment, as an additive to detergent, a chemical for photography, paper-making and oil-field. It is also used as detergent for boiler cleaning and reagent in chemical analysis. 1. High molecular chemical industry: EDTA is used as polymetization activator for butyl bezene latex, and polyreaction terminator in acrylic fibre production. 2.Daily chemicals: EDTA is used as additive to detergent, skin cream and hair-conditioner. 3.Paper-making: EDTA is used for treating the steamed fibre. It will promote the whiteness of paper and reduce the incrustation in the steamer. 4.Pharmaceutical industry: Through cyclopolymerization with methyl amide, EDTA is made into ethyl amide, a remedy for psoriasis. It is also a stablizer for some vaccines and an antihaemoagglutinin. 5. Textile dyeing and printing: EDTA will promote colour ability of the dyestuff and brightness of the dyed fabric.

Storage: Stored in the dry and ventilated inside storeroom, prevent direct sunlight, slightly pile and put down.

EDTA-2NA is a white crystal powder with two crystal water, easy to lose crystal water when dried and easy to soluble in water, but hard to soluble in organic solvents like alcohol or ethyl ether. The pH value of 5%(25 �°C ) aqueous solution is 4.0~6.0. EDTA-2Na is used in detergent, liquid soap, shampoo, agricultural chemicals, fixer solution for development of color film, water cleaner, PH modifier.
