Abstract:

Theoretical results were confirmed in an experimental study of the kinetics of combined mass transfer of two components through a plane boundary in a liquid-liquid system under conditions of SIC. The initial concentration of one of the transferred substances (the macrocomponent) was significantly higher than the concentration of the other transferred substance (microcomponent). The following were investigated: a) unidirectional combined mass transfer of two comonents; b) counter combined mass transfer of two components; and c) individual mass transfer of the microcomponent. The experiments were conducted in a thermostated diffusion cell with the transferred components being cresol (microcomponent) and acetic acid (macrocomponent). In the experiments a) mass transfer of the components was conducted from carbon tetrachloride into water, and in experiments c), transfer of cresol was conducted from both carbon tetrachloride to water and from water to carbon tetrachloride. The experimental data obtained thus suggest that the effects of diffusion and hydrodynamic interactions between the transfereed components become significant during multicomponent mass transfer, both unidirectional and counter, with the high concentration gradients which charaterize conditions of self-organized interphase convection.
