Tetrasodium EDTA

Disodium ethylenediaminetetraacetic acid (EDTA-2Na) is a valuable chelating agent in chemistry. Its chemical formula is C₁₀H₁₄N₂Na₂O₈, and its molecular weight is 336.206. Its molecular structure contains six coordinating atoms (two nitrogen atoms and four oxygen atoms), allowing it to form stable chelates with metal ions. It has important applications in the dye, food, and pharmaceutical industries.

Chemical Properties

Product Usage

It is an important complexing agent and metal masking agent. It can be used in textile dyeing, water treatment, color photosensitive materials, pharmaceuticals, daily chemicals, papermaking, and other industries as an additive, activator, water purifier, metal ion masking agent, and activator in the styrene-butadiene rubber industry. In the dry-process acrylic fiber industry, it counteracts metal interference, improving the color and brightness of dyed fabrics. It can also be used in liquid detergents to improve washing quality and enhance washing effects.
