Reference Information
| Introduction | ethylenediaminetetraacetic acid (EDTA) contains four carboxyl groups, generally can form two salts, three salts and four salts. Common EDTA salts are disodium edetate (EDTA-2Na), tetrasodium edetate (EDTA-4Na), dipotassium edetate (EDTA-2K), and tripotassium edetate (EDTA-3K). Tetrasodium edetate (EDTA-4Na) is a small multifunctional organic molecule containing amino and carboxyl groups, which is widely used in analytical chemistry as a complexing agent. It is widely available and inexpensive. |
| Application | Tetrasodium EDTA is an important complexing agent and metal masking agent. Can be used in the textile industry dyeing, water treatment, color sensitive, pharmaceutical, daily chemical, paper and other industries, as additives, activators, water purification agents, metal ion shielding agent and styrene butadiene rubber industry activator. Dry acrylic industry offset metal interference, improve the color and brightness of the dyed fabric, can also be used in liquid detergent, improve the quality of washing, enhance the washing effect. |
| Use | used as chelating agent, styrene butadiene rubber polymerization initiator, acrylic fiber initiator, etc. used as solvent, also used in rubber, dyestuff Industry It is used as a complexing agent, synthetic rubber catalyst, and water softener for fiber refining, bleaching and dyeing industry |
| production method | is derived from the reaction of ethylenediamine with chloroacetic acid, or from the reaction of ethylenediamine with formaldehyde and sodium cyanide. |
