Abstract: The invention belongs to the technical fields of material preparation and separation, concretely relates to a method for synthesizing a molecularly-imprinted polymer by using a high internal phase emulsion and an application to separation of methyl p-hydroxybenzoate in methyl salicylate and particularly relates to a method for preparing a porous molecularly-imprinted composite membrane of methyl p-hydroxybenzoate (MICMMP) at normal temperature by using a high internal phase emulsion template method, wherein an impurity, namely methyl p-hydroxybenzoate in methyl salicylate is used as a template molecule, styrene is used as a monomer, methyl methacrylate is used as a functional monomer, ethylene glycol dimethacrylate is used as a crosslinking agent, iso-octyl acrylate is used as a plasticizer, and ammonium persulfate and N, N, N', N'-tetramethylethylenediamine are used as initiators; and the selective recognition performance of the prepared molecularly-imprinted composite membrane is researched through a static adsorption experiment and a selective permeability experiment. A result shows that the MICMMP obtained by using the method has excellent molecular recognition and separation performances for methyl p-hydroxybenzoate.
