In this study,the separation models of o-vanillin and vanillin with three-zone simulated moving bed(SMB)and Varicol were built.The separation of these two compounds was achieved successfully with high efficiency and high purity in the experiment.Firstly,the mobile phase of 35%(by vol.)aqueous alcohol and the stationary phase of reverse phase C18 silica gel were determined.The adsorption isotherms of these two compounds were determined with single-component frontal analysis.The lumped mass transfer coefficie...
