Abstract

The invention relates to an ultra-crosslinking organic polymer material and a preparation method and an application of the ultra-crosslinking organic polymer material; and the high-specific surface area ultra-crosslinking organic micropore polymer material is obtained by weighing certain amount of 3,4-dyhydroxyl phenylacetic acid, dissolving in methyl alcohol, adding 1,2-dichloroethane into the solution, adding a crosslinking agent dimethoxymethane and anhydrous ferric chloride under the protection of nitrogen, refluxing and reacting for 5 hours at 45 DEG C, refluxing and reacting for 6-18 hours at 80 DEG C; transferring a product into a conical flask after finishing the reaction, washing with methyl alcohol for multiple times, implementing Soxhlet extraction until a supernate is colorless; and drying under vacuum. The high-specific surface area ultra-crosslinking organic micropore polymer material is applied to separating and analyzing C4-C10 hydrocarbon ingredients like a hexane isomer and methylbenzene in naphtha, and adsorbing and removing cationic dyes like methylene blue, Rhodamine B and Rhodamine 6G in dye wastewater.

Description

technical field [0001] The invention belongs to the field of materials, and relates to a high specific surface nanometer super-crosslinked organic microporous polymer adsorption material, a preparation method and an application. Background technique [0002] The definition of organic microporous polymer IUPAC: a material with a pore size of less than 2 nm, a very high specific surface area, and good physical and chemical stability. It is mainly composed of light non-metallic elements such as carbon, hydrogen, boron and nitrogen. Organic microporous polymers are a relatively new class of materials, which have a wide range of applications and can be used in the fields of heterogeneous catalysis, adsorption, separation and gas storage. Therefore, researchers have a strong interest in the synthesis and application of organic microporous polymer materials. By selecting monomers, crosslinkers of appropriate length, and optimizing reaction conditions, polymeric frameworks with tu...
