EDTA magnesium disodium Usage And Synthesis

Chemical Properties

white powder

Uses

Ethylenediaminetetraacetic acid disodium magnesium salt hydrate (disodium magnesium EDTA) can be used as:     

• A chelating agent in various fields th at binds a wide range of polyvalent cations, including calcium.      
• A nitrogen precursor salt to synthesize nitrogen-doped porous carbon material via direct pyrolysis for supercapacitor applications.

Flammability and Explosibility

Non flammable

Purification Methods

Dissolve it in a small amount of water, filter and precipitate it with an excess of MeOH. Dry it at 80o. [Beilstein 4 IV 2450.]
