Preparation of β-Cyclodextrin Derivatives and Their Application to Thorium

Cyclodextrin is a kind of natural green chiral polymer compound, which has broad application prospects in the fields of environmental analysis, flavor and fragrance inclusion treatment, polymer synthesis technology, pharmacy, and chiral drug resolution. However, simple cyclodextrin is difficult to be further developed and utilized in the fields of solid phase extraction and liquid phase separation due to its poor mechanical properties and solubility. Therefore, it is very urgent and important to solve the current solid-phase derivatization of cyclodextrin in order to obtain better applications in the field of chiral resolution. Using cheap and easy-to-obtain silica gel materials with controllable particle size, good mechanical properties, excellent thermal stability, and acid and alkali resistance as a solid phase carrier, the cyclodextrin grafted on its surface to form a new type of functional material will It is a good choice. Therefore, this thesis mainly studies the preparation of β-cyclodextrin derivatives and the properties of the material and its application to thorium. It mainly includes the following four aspects of work: 1. The basic overview of β-cyclodextrin and its derivatives in the field of environmental analysis, flavors and fragrances, polymer fields, pharmaceutics and chiral resolution related research reports It is a summary summary, and made a feasibility analysis of the topic and the direction of the topic research.
