EDTA-2Na CAS 6381-92-6 Disodium edetate dihydrate acid Industrial Fine Chemicals
The mixture of sodium cyanide and formaldehyde was slowly added into ethylenediamine aqueous solution at a certain ratio, and air was introduced into the solution at 85 ~C and decompression to remove ammonia. After the reaction, the Ph value was adjusted to 4.5 with concentrated sulfuric acid, and the finished product was obtained by decolorization, filtration, concentration, crystallization separation and drying.
