| titleOfInvention | Preparation of novel ionic liquid monomer and polymer thereof and application of novel ionic liquid monomer and polymer thereof in separation of tea polyphenol |
| abstract | The invention relates to the technical field of separation of natural active ingredients, synthesizes a novel amino acid dicationic ionic liquid monomer and a polymer thereof, and is used for selectively adsorbing tea polyphenol. The amino acid ionic liquid has better biocompatibility, and particularly has outstanding selectivity for adsorbing tea polyphenol in tea extract. The novel ionic liquid monomer is further polymerized to form a novel polymer, and the adsorption capacity of the polymer on the tea polyphenol is obviously higher than that of other adsorption media. The polymer is used in tea extractive solution, and can selectively adsorb tea polyphenols (adsorption capacity of 500mg/g adsorbent), and retain other impurity components such as caffeine in the extractive solution. The method simplifies the conventional tea polyphenol preparation process; can be recycled without using organic solvents and adsorbents, and has excellent ecological environmental protection and safety. The method provides a new high-efficiency way for extracting and preparing high-purity tea polyphenol from tea leaves. |
