Patent Title: Method for preparing vanillin molecular engram polymer
Publication date: 2007
Publication number: CN101085816

Abstract: The invention discloses a method for preparing vanillin molecular imprinting polymer by separating and extracting vanillin produced in industrial process, belonging to high- molecule polymerization field. It comprises following steps: dissolving vanillin module moledule and methacrylamide functional monomer into disslovant, adding crosslinking agent, emulsifying agent and initiator under supersonic condtion, water bathing and getting polymer containing imprinting molecule inside; washing polymer to remove vanillin molecule bond inside of polymer and getting final product. The maximum recovery rate for vanillin is 91%, which is far higher than that of 72% in current industrial separation method. There is no inorganic salt wastewater generation during vanillin separation process. The imprinting polymer is a kind of high- efficiency and clean environmental- protecting material, and the application prospect is quite good.
