What are the criteria for stability in a liquid-liquid system?
Answers
Hey mate!
Your answer:
Liquid–liquid extraction (LLE), also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar). There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to organic.

Temperature gradients, resulting from thermal effects due to heats of solution and mixing, which accompany mass transfer in partially miscible liquid pairs, were found to be of the same order of magnitude as those leading to thermal instability in shallow liquid layers. Linearised perturbation analysis was therefore applied to such binary liquid systems, using linearised profiles, and the characteristic equation was analysed for the onset of spontaneous Marangoni-type interfacial convection. The stability criteria indicate that binary systems may be stable or unstable in both directions of transfer or unstable in only one direction of transfer
