Liquid extraction with single droplets-effect of chemical reaction

"The circulating drop mass transport model based on Hadamard's dispersed phase stream function was solved numerically to account for a solute diffusing into a droplet and undergoing a first order irreversible reaction with the drop medium for the case where the continuous phase resistance to solute transport is negligible ... Experimental data were obtained for a system which consisted of 2-chloro-2-methylpropane (t-butyl chloride) diffusing from a benzene continuous phase into falling water droplets and undergoing a first order irreversible reaction with the water droplets ... The experimental solute transport rates were a factor of 7 to 10 greater than those predicted by the circulating drop model (or Penetration theory) and a factor of 2.5 to 3 greater than those predicted by the Handlos and Baron model ... From visual observations of a stationary droplet in contact with the continuous phase during the transfer process, it was concluded that the deviation between the theoretical models and the experimental data was due to a special type of interfacial motion not usually observed when two liquids are in contact"--Abstract, page i-ii.
