Abstract

The invention is a molecularly imprinted polymer and a preparation method thereof. The name of the molecularly imprinted polymer is a molecularly imprinted polymer containing a three-membered phenanthrene ring skeleton, and its preparation method is: using maleic rosin ethylene glycol propylene ester as a crosslinking agent, dehydroabietylamine or theophylline as a template molecule, Acrylic acid or derivatives of acrylic acid such as methacrylic acid, methyl methacrylate, acrylamide, etc. are used as monomers, in a 500 ml three-necked flask, gasoline-chloroform-water mixed solvent is used as a solvent, an initiator is added, heated, Stir and carry out free radical suspension polymerization to obtain a polymer product, then use a methanol-acetic acid mixture to elute the polymer in a Soxhlet extractor, remove the template molecule dehydroabietylamine or theophylline, and obtain a Molecularly imprinted polymers, that is, molecularly imprinted polymers containing a three-membered phenanthrene ring skeleton, can be used for the adsorption and separation of organic compounds.

Description

technical field [0001] The invention relates to a molecularly imprinted polymer and a preparation method thereof, more specifically, the invention relates to a molecularly imprinted polymer containing a three-membered phenanthrene ring skeleton and a preparation method thereof. Background technique [0002] So far, the extraction of natural macromolecular compounds such as alkaloids, flavonoids, saponins and other active ingredients of Chinese herbal medicines usually uses solvent extraction, supercritical liquid extraction or recrystallization methods. These methods can extract the active ingredients of Chinese herbal medicines, but the disadvantages are that these methods have a long process flow, low extraction rate or complicated equipment. Using molecularly imprinted polymers containing ternary phenanthrene ring skeletons to extract natural macromolecular compounds such as alkaloids, flavonoids, saponins and other active ingredients of Chinese herbal medicines not only ...
