Conductometric studies of the thermodynamics complexation of Li+, Na+, K+, Mg2+, and Ba2+ ions with 4′,4″(5″)-Di-tert-butyldibenzo-18-crown-6 ligand in acetonitrile, ethanol and methanol solutions

Kilo-scale synthesis and purification of 4,4′-[di-t-butyldibenzo]-18-crown-6 and its catalytic reduction to 4,4′-[di-t-butyldicyclohexano]-18-crown-6

“…Based on the nature of metal ions and organic solvents, DTBDB18C6 also shows varying degrees of selectivity for solvent extraction of different metal ions like Mg, Ba, K, Na, and Li. 7 The highly selective nature of DTBDB18C6 has also made it a very suitable candidate for ion sensitive sensors and electrodes. 8 On the other hand, 4,4′-[di- t -butyldicyclohexano]-18-crown-6 (DTBDCH18C6) has the potential to recover strontium from high level nuclear waste.…”
