| titleOfInvention | Chelating agent with high stability and high iron chelating ability and preparation method thereof |
| abstract | The invention relates to a chelating agent with high stability and high iron chelating ability and a preparation method thereof. The chelating agent is a target compound which is prepared from phenol derivatives, aliphatic diamine and glyoxalic acid aqueous solution serving as initial materials by mannich reaction in a one-step synthesis manner. By adopting the preparation method disclosed by the invention, the defects of fussy synthesis steps, low yield and poor selectivity of the traditional chelating agents such as EDDHA (ethylenediamine-N,N'-diacetic acid) are overcome; and the obtained chelate has higher stability and iron chelating ability relative to EDTA (ethylene diamine tetraacetic acid) and EDDHA. |
