| titleOfInvention | Novel calixarene derivative, rare earth metal extractant containing the derivative as an active ingredient, and method for separating and purifying rare earth metal |
| abstract | (57) [Summary] [Structure] General formula (I) (In the formula, R 1 represents an alkyl group having 6 to 18 carbon atoms, R 2 represents a group selected from -CH 2 COOH, -CH (CH 3 ) COOH or -C (CH 3) 2 COOH, n is an integer of 4-8. ), A calyx arene derivative represented by the formula (1), a rare earth metal extractant containing the derivative as an active ingredient, and a separation and purification method using the derivative. [Effect] Compared with conventional metal extractants, the extraction selectivity between rare earth metals is significantly improved, and rare earth metals can be efficiently separated and purified. |
