In order to study the effect of silicone oil on n-hexane mass transfer in a two liquid-phase stirred reactor, the partition coefficient H between air and water/silicone oil mixture was obtained by a static headspace method. The maximum fraction of n-hexane transferred from the gas to liquid phase βS* was calculated by model fitting, and the effectiveness-number of transfer unit method (ε-NTU method) was used to determine the overall volumetric mass transfer coefficient KLa. The results show that the H values decrease significantly with the increased proportion of silicone oil φ and the "Equivalent absorption capacity" model could describe the relation between H and φ. With the addition of silicone oil, βS* increases sharply as φ increases, but it decreases with the increase of inlet air flow QG. Moreover, KLa decreases with the increase of φ, but silicone oil induces the increase of saturated liquid n-hexane concentration C*, thereby increase the overall mass transfer rate of n-hexane. © 2020, Editorial Board of "Journal of Chemical Engineering of Chinese Universities".
