| titleOfInvention | A kind of pyridyl calix[4]arene derivative, its preparation method and application as manganese ion extraction agent |
| abstract | The invention discloses a pyridyl-containing calix[4] arene derivative, a preparation method and an application as a manganese ion extraction agent. The pyridyl-containing calix[4]arene derivative is obtained by nucleophilic substitution reaction of alkyl calix[4]arene and 2-(halomethyl)pyridine hydrochloride under base catalysis; the pyridyl-containing calix[4] Aromatic derivatives have high physical and chemical stability, good oil solubility, insoluble in water, and have good ability to recognize and complex metal ions. They are combined with P204 to form a synergistic extraction system, which is effective against the presence of manganese ions in the sulfate solution system. It has strong positive synergistic extraction effect, and has obvious reverse synergistic extraction effect on metal ions such as nickel, cobalt, magnesium, and lithium. It is very suitable for the selective extraction and separation of manganese ions in complex metal ion systems, and has good industrial application prospects. . |
