Character: EDTA-2Na is a white powder with two crystal waters, 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% (25C) Water solution is 4.0-6.0.

 

 

Application:

EDTA-2Na is used in detergent, liquid soap, shampoo, agricultural chemicals, fixer solution for development

of colour film, Water cleaner, PH modifier. When stating the redox reaction for the polymerization of butyl

Benzene rubber, it is used as Part of activator for the complexation of metal ion and control of polymerization speed.
