Product Description

Disodium EDTA

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.

Properties: white crystal powder soluble in water, and a variety of metal ion chelation.

Product Application

This product is used as bleaching fixing solution and dyeing aid, fiber treatment agent, coagulant,complexing agent, detergent, stabilizer, synthetic rubber, polymerization initiator of heavy metal quantitative analysis agent, etc., lies in the initiation system.

Disodium EDTA, as a component of active agent, is mainly used in cosmetics for complexing iron ions and controlling polymerization.The reaction speed, at the same time, can also be used for cleaning.

Among the salts of ethylenediaminetetraacetic acid, the disodium salt is the most important.

1. It is an important complexing agent. It can also be used in electroless copper plating, gold plating, lead-tin alloy plating, electrochemical polishing of steel parts and solutions before silver plating of copper.

2. laced by EDTA-Na. Also used in detergents, liquid soaps, shampoos, agrochemical sprays,color photographic materials, bleaching fixers, water purifiers, pH adjusters, anticoagulants, etc.

3. In the reduction initiation system for the polymerization of styrene-butadiene rubber,disodium EDTA is used as a component of the active agent, and is mainly used for complexing ferrous ions to control the polymerization rate.

In total,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.
