Use | It is used as a color photosensitive material rinsing, processing, bleaching and fixing solution, an activator of styrene-butadiene rubber, a hard water softener, a sequestering agent, etc. EDTA four sodium in various pH range and various concentrations of hard water containing calcium has the ability to complex, and in the pH 8 or more the highest time. Complexed with calcium metal in a molar ratio of 1:1, it has excellent thermal stability in water and does not decompose even in superheated water. It is a very effective hard water softener. This product is non-toxic. |
production method | This product is an intermediate product for the production of ethylenediaminetetraacetic acid, and the process can be seen in the previous entry. |
