A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 14098-44-3, Name is Benzo-15-crown-5, molecular formula is C14H20O5.

A novel approach for the selective extraction of Li+ from the leaching solution of spent lithium-ion batteries using benzo-15-crown-5 ether as extractant
In order to selectively extract Li+ from the leaching solution of spent lithium-ion batteries, benzo-15-crown-5 ether (B15C5) is synthesized and used as a lithium extractant. The selectivity of B15C5 to Li+ is studied from the two aspects of experiment research and density functional theory (DFT) calculation. Under the experimental conditions of pH of 6.0, temperature of 30 C and extraction time of 2 h, the extraction rate of Li+ is 37%, which is well above that of the possible impurity ions Co2+, Ni2+ and Mn2+. The DFT calculation about structure optimization, charger transfer, electron density difference, natural bond orbital (NBO) analysis, binding energy and free energy change are carried out, and the extraction mechanism of B15C5 is revealed. The results show that B15C5 should combine Li+ preferentially in solution. The calculated values are consistent to the experimental results. Therefore, this paper provides a new feasible method to recover Li from the leaching solution of spent lithium-ion batteries, and it is conducive to the sustainability of the lithium resources.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.SDS of cas: 14098-44-3, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 14098-44-3, in my other articles.
