EDTA) — органическое соединение, четырёхосновная карбоновая кислота с химической формулой (HOOCCH2)2N(CH2)2N(CH2COOH)2, белый мелкокристаллический порошок, малорастворим в воде, нерастворим в большинстве органических растворителей, растворим в щелочах, с катионами металлов образует соли этилендиаминтетраацетаты. Получают конденсацией этилендиамина с монохлоруксусной кислотой. https://ru.wikipedia.org/wiki/Этилендиаминтетрауксусная_кисл... Ethylenediaminetetraacetic acid (EDTA), also known by several other names, is a chemical used for both industrial and medical purposes. It was synthesised for the first time in 1935 by Ferdinand Münz.[4] It is an aminopolycarboxylic acid and a colourless, water-soluble solid. Its conjugate base is ethylenediaminetetraacetate. It is widely used to dissolve limescale. Its usefulness arises because of its role as a hexadentate ("six-toothed") ligand and chelating agent, i.e., its ability to sequester metal ions such as Ca2+ and Fe3+. After being bound by EDTA into a metal complex, metal ions remain in solution but exhibit diminished reactivity. EDTA is produced as several salts, notably disodium EDTA, calcium disodium EDTA, and tetrasodium EDTA (typically as the hydrate). https://en.wikipedia.org/wiki/Ethylenediaminetetraacetic_aci... |
