The volume concentration of the liquid-liquid multiphase during the stirring process determines the droplet size of the dispersed phase and the contact area of the two phases,which in turn determines mass transfer,heat transfer and chemical reaction rate between the two *** stirring process of the immiscible liquid-liquid multiphase in the stirred tank was studied by CFD *** was found that the volume fraction of the dispersed phase has a significant effect on the average droplet diameter,the fluid flow rate,and the liquid phase kinetic *** the impeller velocity was constant,the volume fraction of the dispersed phase had relationship with these fluid *** was an important guiding significance of this work on the synthesis reaction in the chemical industry.

Macroporous cellulose monolith as chromatographic support was successfully fabricated from an ionic liquid dissolved cellulose solution by an emulsification method and followed by the cross-linking reaction and DEAE *** the physical characterization,the cellulose monolith featured by both the interconnected macropores in range of 0.5-2.5 μm and the diffusion pores centered at about 10 *** the bimodal pore system,the monolith possessed the specific surface area of 36.4 m2 g-1 and the column permeability of about 7.45×10-14 *** the DEAE modification,the anion cellulose monolith was evaluated for its chromatography *** demonstrated that the static and dynamic adsorption capacity of BSA reached about 66.7 mg mL-1and 43.9 mg mL-1 at 10% breakthrough point,*** results were comparable to other chromatographic *** this way,the prepared cellulose monolith with bimodal pores system is expected for the potential application in high-speed chromatography.
