Embodiment 1

[0034] Synthesis of [VBTEA]Cl. Add 3.393g of p-chloromethylstyrene and 2.021g of triethylamine into a 100mL three-necked round-bottomed flask, then add 15mL of anhydrous acetonitrile, stir and react at 45°C for 12h, there will be precipitates in the solution, after the reaction , the mixture was poured into diethyl ether to wash three times, and finally vacuum-dried at room temperature for 24 h to obtain a white solid product [VBTEA]Cl with a yield of 85%.

Embodiment 2

[0036] [VBTEA] PF 6 Synthesis. Add 4.311g of [VBTEA]Cl and 3.502g of potassium hexafluorophosphate into a 100mL single-necked round-bottomed flask, then add 0.051g of 2,6-di-tert-butyl-4-methylphenol and 15mL of anhydrous acetonitrile at 25 The reaction was stirred at ℃ for 48 hours. After the reaction, the precipitate formed was removed by filtration, the filtrate was poured into ether and washed 3 times, and the obtained solid precipitate was vacuum-dried at room temperature for 24 hours to obtain the white solid product [VBTEA]PF 6 , the yield was 90%.

Embodiment 3

[0038] P[VBTEA]PF 6 Synthesis. Under a nitrogen atmosphere, 10mL DMF was added to a 50mL reaction eggplant-shaped flask, and then 3.002g [VBTEA]PF 6 Dissolve in DMF, then add 0.030g AIBN, then raise the temperature to 60°C, and react at constant temperature for 6h. After the reaction, pour the mixed solution into a large amount of methanol to precipitate, and the obtained solid is vacuum-dried at 100°C for 24h to obtain white final Product P[VBTEA]PF 6 , the yield was 75%.

Abstract

The invention provides a kind of synthetic method of novel quaternary ammonium hexafluorophosphate ionic liquid polymer, that is: poly(p-vinylbenzyl-triethyl quaternary ammonium hexafluorophosphate), which first uses triethylamine and p- Chloromethylstyrene is subjected to quaternization reaction, then ion-exchanged with potassium hexafluorophosphate to obtain monomer, and finally poly(p-vinylbenzyl-triethyl quaternary ammonium hexafluorophosphate) is obtained through free radical polymerization. The ionic liquid polymer has good thermal stability and high glass transition temperature, and can be used for the capture of harmful gases such as carbon dioxide, sulfur dioxide, formaldehyde, and dioxin, the solid-phase extraction and separation of sulfur and nitrogen heterocyclic compounds in oil products, and Solid phase electrolyte materials and other fields.

Description

technical field [0001] The invention belongs to the field of chemical synthesis, and relates to a novel quaternary ammonium hexafluorophosphate ionic liquid polymer and a synthesis method thereof. The polymer can be used for trapping harmful gases such as carbon dioxide, sulfur dioxide, formaldehyde, and dioxin, and for oil products Solid phase extraction and separation of sulfur and nitrogen heterocyclic compounds, and solid phase electrolyte materials and other fields. Background technique [0002] Ionic liquids are a brand-new green solvent or material that has only been developed in the past ten years. They are a class of organic salts composed entirely of organic cations and inorganic / organic anions. Compared with traditional inorganic salts, ionic liquids have a much lower melting point, and are usually in a liquid state at room temperature or below. In addition, they are non-volatile, wide liquid range, wide electrochemical window, and good dissolution and absorption ...
