| titleOfInvention | Compounds, separation methods, and uses thereof for chromatographic separation of rare earth elements and s-, p-, d-metals |
| abstract | The present invention relates to compounds of the general formula (I) for the chromatographic separation of rare earth elements and/or s-, p- and d-zone metals, and to a process for the separation of rare earth elements: In the above formula, - X is H; C 1 to C 6 alkyl; halogen (F, Cl, Br or I); Y is nitrogen; selected from the group consisting of N-oxides; Z 1 , Z 2 , Z m where m is 1 or 2 are independently selected from the group consisting of —CH 2 —CH 2 — and —CH 2 —CH 2 —CH 2 —; A, A m , wherein m is 1 or 2, is independently H; -CH 2 COOH; —CH 2 C(O)NH 2 ; —CH 2 P(O)(OH) 2 and is selected from; - n is 1 or 2; R 1 , R 2 , R 3 are independently H; C 1 to C 6 alkyl; C 1 to C 6 alkyloxy; C 6 to C 10 aryloxy; benzyloxy; C 1 to C 6 alkylthio; C 6 to C 10 arylthio; F; Cl; Br; I; OH; SH; NH 2 ; C 1 to C 6 alkylamino; di(C 1 to C 6 alkyl)amino; C 1 to C 6 acylamino; di(C 1 to C 6 acyl)amino; C 6 to C 10 arylamino; di(C 6 to C 10 aryl)amino; CN; OH; nitro; COOR n , C(O)NHR n , C(O)N(R n ) 2 , wherein R n is independently H or C 1 to C 10 alkyl or C 6 to C 10 aryl; two neighboring R 1 , R 2 , R 3 together with the two neighboring carbon atoms of the aromatic ring are OH, SH, CF 3 , F, Cl, Br, I, C 1 to C 6 alkyl, C 1 to C 6 alkyloxy, C 1 to C 6 alkylthio, NH 2 , C 1 to C 6 alkylamino, di(C 1 to C 6 alkyl)amino, NO 2 , COOH, COOR n , C(O)NHR n optionally substituted with one or more substituents independently selected from the group consisting of , C(O)N(R n ) 2 , wherein R n is independently H or C 1 to C 10 alkyl or C 6 to C 10 aryl to form a 6-membered ring; However, when n is 2 and Z 1 , Z 2 , and Z m are all —CH 2 —CH 2 —, A is not —CH 2 COOH. |
