Embodiment 1

[0023] Preparation of High Specific Surface Nonflammable Polymer Adsorption Material

[0024] Add the two reactants according to the measured molar ratio (1mmol benzene and 1mmol chloromethylbenzene) into a 250ml three-necked flask, add 120ml nitrobenzene to fully swell, then add 0.2mmol of aluminum trichloride to catalyze the reaction, at 40°C The reaction was carried out under nitrogen protection for 3 hours, and then the temperature was raised to 60° C. for 12 hours. After the reaction, cool to room temperature, filter, wash with a small amount of petroleum ether, a large amount of tap water, 0.5mol / L hydrochloric acid solution, etc., and then use acetone as an extractant to reflux the product with a Soxhlet extractor, and finally dry it in vacuum at 100°C 48 hours to get the final product.

Embodiment 2

[0026] Add the two reactants according to the measured molar ratio (1mmol toluene and 5mmol dichloromethylbiphenyl) into a 500ml three-necked flask, add 200ml trichloroethane to fully swell, add 0.2mmol ferric chloride and 0.1mmol Zinc trifluoroacetate catalyzed the reaction, reacted under nitrogen protection at 60°C for 6h, and then raised the temperature to 80°C for 24h. After the reaction, cool to room temperature, filter, wash with a small amount of petroleum ether, a large amount of tap water, 0.5mol / L hydrochloric acid solution, etc., and then use acetone as the extraction agent to reflux the product with a Soxhlet extractor, and finally vacuum the product at 120 ° C. Dry for 24 hours to get the final product.

Embodiment 3

[0028]Add the two reactants into a 500ml three-necked flask according to the measured molar ratio (1mmol benzene and 8mmol chloromethylbenzene), add 120ml nitrobenzene, 100ml chlorobenzene and 30ml cyclohexane to fully swell, then add 0.2mmol trifluoro Ferric sulfonate, 0.1 mmol of boron trichloride and 0.1 mmol of tin tetrachloride catalyzed the reaction, reacted under nitrogen protection at a temperature of 5° C. for 2 hours, and then reacted at an elevated temperature of 100° C. for 48 hours. After the reaction, cool to room temperature, filter, wash with a small amount of petroleum ether, a large amount of tap water, 0.5mol / L hydrochloric acid solution, etc., and then use acetone as the extractant to reflux the product with a Soxhlet extractor, and finally vacuum the product at 160 ° C. Dry for 48 hours to get the final product.

[0029] The above description of the embodiments is for those of ordinary skill in the art to understand and apply the present invention. It is ...

Abstract

The invention relates to a high-molecule adsorption material, which is a polymer with a novel resin structure and is greatly different from the conventional phenylethylene crosslinked high-molecule adsorption resin. A main body structure of the high-molecule adsorption material is a network structural system consisting of an aromatic benzene ring and a methylene structure which are connected with each other. A preparation method comprises the following steps of: performing continuous pay-gram alkylation polymerization reaction on a derivative such as benzene-type aromatic hydrocarbon and the like and a precursor dichlorine methyl-type rigid cross-linking agent; and synthesizing a novel non-combustible adsorption material and non-phenylethylene type adsorption resin material. The material is high in polymerization reaction yield, and can be applied to fields of air purification, such as leakage treatment for dangerous chemical substances, adsorption and elimination of industrial poisonous and harmful substances, treatment for tail gas from a factory, effective and quick absorption and removal of oil pollution on a water surface and the like, research and development on relevant protection materials of personal safety protection devices and the like.

Description

technical field [0001] The invention relates to the preparation of a polymer adsorption material, and the evaluation and use method of using the adsorption material to purify surfaces polluted by hazardous chemicals (including: toxic and harmful pollutants in the air, toxic and harmful industrial chemicals TICs such as benzene, etc.). Background technique [0002] In recent years, the leakage of dangerous chemicals (such as pesticides, and toxic and harmful industrial chemicals TICs, etc.) caused by sudden natural disasters and accidents has become one of the major threats to public safety; in addition, in recent years, terrorist activities Increasingly, they may use dangerous chemicals (such as: toxic and harmful industrial chemicals TICs, etc.) to carry out surprise attacks on densely populated areas. The rapid and efficient decontamination of personnel, places and objects in the affected area has become the most important means to ensure the safety of personnel in the abo...
