The degradation of TBP has become a stumbling block to the industrial continuous production of lithium chloride extraction from brines with high Mg/Li ratio by solvent extraction To develop a more stable and more efficient extraction system, a novel amide system, containing newly synthesized extractant N,N-bis(2-ethylhexyl)-2-methoxyacetamide (NBEHMOA), FeCl3 6H2O and sulfonated kerosene, was proposed in this work. Compared with TBP and N523, NBEHMOA extracted Li+ and H+ in the sequence of TBP NBEHMOA N523 and N523 TBP NBEHMOA resp. The solution containing 5.5 mol/L LiCl and 0.5 mol/L HCl was used as the eluent in the scrubbing process. A Li+ extraction efficiency of 96.7% and 22.31 g/L Li+ in the stripping solution were achieved by the whole process with counter-current twelve stages. The extraction mechanism investigated via FT-IR spectroscopy illustrated that the metal ions Fe3+ and Li+ were mainly coordinated by the carbonyl C = O in NBEHMOA. This novel amide system can successfully achieve the cascade extraction effect for lithium, Li/Mg separation and avoid the generation of phase interface objects through counter-current extraction of lithium from brine at a lower acidity. This work provided a novel extraction system to recover lithium from the higher magnesium/lithium ratio brines. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Product Details of 7447-41-8).
Lithium chloride (cas: 7447-41-8) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.Product Details of 7447-41-8
