Reactive extraction . A brief survey of reactive extraction and its classification is followed by an account of the reactive extraction of organic solutes. As an example, the reactive extraction of salicylic acid with a secondary amine and NaOH is discussed. Equilibrium constants, overall mass transfer coefficients evaluated in stirred cells and on fixed, freely suspended and pulsated droplets, as well as mass transfer coefficients for the particular phases are investigated. The influence of droplet volume, solute concentration, pH value, and the fluid‐dynamic state of the droplet on the overall and fractional mass transfer coefficients are discussed and compared with various mass transfer models.
