5-amino-8-hydroxyquinoline-alginic acid polyolefin material ash removal agent, its preparation method and application

Abstract

The application provides a 5-amino-8-hydroxyquinoline-alginic acid polyolefin material ash removal agent and a preparation method and application thereof, and the ash removal agent has a structure of formula I. In the application, 5-amino-8-hydroxyquinoline and alginic acid are connected by a chemical bond to form an ash removal agent of a polyolefin solution. Compared with the prior art, the ash removal agent has more active sites, can be fully complexed with metal ash, and can effectively remove metal ash in a polypropylene material; the preparation method of the ash removal agent is simple, the ash removal rate is fast, the removal rate of metal ions is high, the adsorption capacity is large and the like; and the ash removal agent is not limited to the basic ash content of the polyolefin material, has a wide raw material source, has good stability, can meet the requirements of a fixed bed reaction device, is not limited by a basic production process, and does not affect the stability and continuity of normal production.
