Ethylenediaminetetraacetic acid (EDTA) contains four carboxyl groups, which can generally form two salts, three salts and four salts. Common EDTA salts include disodium ethylenediaminetetraacetate (EDTA-2Na), tetrasodium ethylenediaminetetraacetate (EDTA-4Na), dipotassium ethylenediaminetetraacetate (EDTA-2K) and tripotassium ethylenediaminetetraacetate (EDTA-3K). Tetrasodium ethylenediaminetetraacetate (EDTA-4Na) is a multifunctional organic small molecule containing amino and carboxyl groups, which is widely used in analytical chemistry as a complexing agent. It is widely sourced and cheap. The application of tetrasodium EDTA is an important complexing agent and metal masking agent. It can be used in textile industry dyeing, water treatment, color sensitization, medicine, daily chemical industry, paper making and other industries as additives, activators, water purification agents, metal ion shielding agents and activators in styrene butadiene rubber industry. In the dry process acrylic fiber industry, it can offset metal interference, improve the color and brightness of the dyed fabrics, and can also be used in liquid detergents to improve the washing quality and enhance the washing effect. Chemical properties White crystalline powder. Soluble in water and acid, insoluble in alcohol, benzene and chloroform. Uses It is used as a chelating agent, styrene butadiene rubber polymerization initiator, acrylic fiber initiator, etc. It is also used as a solvent in rubber and dye industries, as a complexing agent for ammonia carboxyl, and as a catalyst for synthetic rubber. It is also used as a water softener in fiber refining, bleaching and dyeing industries. It is produced by the reaction of ethylene diamine with chloroacetic acid, or by the reaction of ethylene diamine with formaldehyde and sodium cyanide.
