Glycine, N,N′-1,2-ethanediylbis[N-(carboxymethyl)-, sodium salt, hydrate (1:4:2) Use and Manufacturing

Methods of Manufacturing

This product is an intermediate product for the production of ethylenediaminetetraacetic acid, and the technological process can be referred to the previous entry.

Uses

Used as a bleaching and fixing solution for color photosensitive materials, activating agent for styrene-butadiene rubber, hard water softener, sequestering agent, etc. Tetrasodium EDTA has complexing ability to calcium-containing hard water in various pH ranges and various concentrations, and has the highest effect when pH≥8. Complexed with calcium metal in a 1:1 molar ratio, it has excellent heat stability in water and will not decompose even in superheated water. It is a very effective hard water softener. This product is non-toxic.
