Among the salts of ethylenediaminetetraacetic acid, the disodium salt is the most important and is an important complexing agent for complexing metal ions and separating metals. It can also be used in detergents, liquid soaps, shampoos, and agricultural chemical sprays. The agent, the color photosensitive material, the bleaching fixer, the water purifying agent, the pH adjusting agent, the cation agent, and the like. In the redox initiation system for styrene-butadiene rubber polymerization, disodium EDTA is used as a component of the active agent to mainly complex ferrous ions and control the polymerization rate. This product is low in toxicity, and the oral LD50 of rats is 2000 mg/kg.
