Experimental measurements of mass transfer coefficients in a stirred cell and in a bubbling agitated contactor are reported for the system oxygen-cyclohexane over a range of temperatures. The results indicate differences in the mechanics of mass transfer between the two cases, the mass transfer coefficient in the bubbling contactor remaining almost constant over the entire range of temperatures. Variation in the physical properties of the liquid probably influence the mass transfer behaviour differently in the two cases. The effect of such variations is not explicitly considered in the current theories of mass transfer across an interface.
