N2 - Cyclohexanone and cyclohexanol are products of selective oxidation of cyclohexane. They are important industrial intermediates and difficult to be separated due to their close boiling points. In this work, well-intergrown ZIF-78 membrane was successfully synthesized on the porous silica substrate by secondary growth method and applied for separation of cyclohexanone/cyclohexanol mixture for the first time. Meanwhile, a facile method for seeding procedure was developed by utilizing the amorphous ZIF-78 precursors to provide better-distributed nucleation sites. Both XRD and SEM results confirmed the good quality of the membrane. The pervaporation separation of cyclohexanone/ cyclohexanol mixture were carried out at room temperature with permselectivity of 1:2 and total flux around 8.7 × 10-2 kg m-2 h-1. © 2013 Elsevier Inc.
