Triazin ring containing covalent organic microporous polymer and application method and application thereof

Abstract

The invention provides a triazin ring containing covalent organic microporous polymer. The triazin ring containing covalent organic microporous polymer with gas adsorption properties has quite high nitrogen content and a microporous structure, the contact area between the gas and the polymer is greatly increased, and the adsorption efficiency is greatly improved; in addition, the triazin ring containing covalent organic microporous polymer only needs zinc as a catalyst and is cheap and environmental friendly, and after action, the pure polymer can be obtained by simple filtration and cleaning;the polymer material has good application prospect in the fields of adsorption and the like.

Description

technical field

[0001] The invention relates to a polymer, in particular to a covalent organic microporous polymer containing a triazine ring, which belongs to the field of gas adsorption materials. Background technique

[0002] Due to global attention to the issue of greenhouse effect and carbon dioxide emission reduction, at the same time CO 2 It is also a potential carbon resource, making CO 2 Recycling, fixation, utilization and re-recycling have become a problem of great concern to countries all over the world. Coal-based thermal power plants emit CO 2 large households, if the CO in the flue gas can be 2 Recycling is a work that has both good social and economic benefits. After people's long-term exploration and research, the research shows that: the polyamino group in the molecular structure of the adsorption system is beneficial to improve the absorption performance.

[0003] For a long time, the adsorption of CO 2 Most of the adsorbents use chemical solutions f...

[0065] The preparation of poly(2,4,6-three (p-cyanoaniline)-1,3,5-triazine) comprises the following steps:

[0066] Add 429mg (1mmol) 2,4,6-tris(p-cyanoaniline)-1,3,5-triazine, 613.4mg (5mmol) zinc chloride to the sealed tube and grind with a mortar under infrared lamp Evenly, then put into the sealed tube. After the tube was sealed, it was placed in a muffle furnace at 600°C for 40 hours of reaction to obtain a polymer. After the reaction is complete, put the polymer in a 500ml flask, add 200ml of distilled water, ultrasonicate for 1h, then wash at 90°C for 12h under stirring, filter, then stir in 0.1M dilute hydrochloric acid for 12h, filter, wash with water until neutral, and then use Washing with dimethyl sulfoxide and acetone, the polymer is obtained after vacuum drying, and its synthetic route is as follows: figure 1 Shown; its nitrogen adsorption-desorption curve and pore structure distribution are as follows figure 2 and image 3 Shown; its carbon dioxide adsorpti...
