Time:  10:30  

Lecture Content:

Separating homologues are more challenging due to their similar molecular structure and physicochemical properties. Conventional methods such as chromatographic separation techniques have disadvantages such as slow diffusion rate, small separation capacity, high solvent consumption and high energy consumption for recovery. Liquid-liquid extraction has the advantages of large separation capacity, continuous process, simple equipment, etc. However, the liquid-liquid two-phase extraction system composed of molecular solvents often lacks synergistic effects between molecules, and the separation selectivity is not satisfactory, and it is difficult to realize structural similarities. Highly selective separation, therefore, breaking the limitations of molecular solvents and constructing an extraction medium with molecular recognition ability is the key to achieving high-capacity and high-selective extraction and separation of homologues. Efficient separation demonstrates the enormous potential of molecular identification, extraction, and separation technology for homolog separation.
