| titleOfInvention | PROCESS FOR PREPARING NEW CALIXARINE DERIVATIVES WITH MIXED IONOPHER GROUPS USED FOR THE EXTRACTION OF METALS OF TECHNICAL INTEREST |
| abstract | The invention relates to a process for the preparation of calicarene derivatives used for the extraction of metallic ions from aqueous solutions. The process according to the invention is carried out in two steps by treating the base calicarbate with 2-butenyl bromide and the bromoacetic acid ethyl ester or chlorine-N, N-diethylacetamide in the presence of sodium hydride in acetonitrile, tetrahydrofuran and / or dimethylformamide as a solvent, resulting in derivatives of the cannula [n] arenas in which n has the value of 4, 6, 8 with 2-butenyl (crotyl) -ethylamido and 2-butenyl (crotyl) . |
