Experimental results of mass transfer in air‐water system with a dispersed immiscible organic liquid in a bubble column 0.076 m in diameter for seven different organic liquids at various hold‐up are presented. Experiments are carried out at gas superficial velocity in the range 0.0052‐0.026 m/s at 293 K. The volumetric mass transfer coefficient, k L a is determined by dynamic gas absorption technique. Overall gas hold‐up is also measured. Slight addition of n‐decane, dodecane and n‐heptane in air‐water medium significantly enhances mass transfer from the gas phase, to the continuous aqueous phase whereas toluene, anisole and 2‐ethyl‐1‐hexanol retard mass transfer.
