Abstrac

-Mean drop sue. fractronrd hold-up of drspersed phase and axral mrxmg charactenstrcs have been determmed m a 72 mm dtameter mechamcally agttated extractron column of Oldshue-Rushton type, usmg the two hqmd-hquid mass transfer systems, toluene-acetone-water and MlBK-acetic acid-water As for normal condrtrons of packed column operatton descrrbed m Part I, solute presence and the drrectron of mass transfer has a stgntficant effect on mean drop srze, fracttonal hold-up and to a lesser extent, axraf mwng m the drspersed phase Probably the most dramattc effect however IS the manner m whtch solute transfer affects dispersed phase behavrour Highly coalescmg conditions with transfer from the Qspersed to the contrnuous phase can make the column practically unoperabie As for the packed column, axial mrxmg m the contmuous phase ts una8ected except m so far as solute presence and due&on of mass transfer affect the hold-up of dtspersed phase
