Modeling of Single Droplet Mass Transfer of Acetic Acid with Triisooctylamine‐Based Solvent

Abstract The design of mass transfer equipment based on single droplet mass transfer data is still a great challenge, although having been subject of intensive discussion for decades already. Extraction with chemical reaction may rather contribute to additional problems when modeling single droplet mass transfer. Single droplet mass transfer of acetic acid from aqueous carrier into triisooctylamine based solvents modified with the Lewis acid modifier isodecanol and the diluent Shellsol T has been investigated. Mass transfer of acetic acid into triisooctylamine‐based solvent droplets is strictly controlled (actually limited) by diffusion of the laden solvent from the interface into the droplet bulk phase.
