Embodiment 1
[0040] Embodiment 1, the synthesis of anion acceptor compound
[0041] (1) Synthesis of intermediate 2,6-diformyl-4-chlorophenol:
[0042] a. Preparation of 2,6-dimethylol-4-chlorophenol
[0043] Slowly heat the mixture of 15 grams of p-chlorophenol, 7.8 grams of paraformaldehyde and 1.2 grams of sodium hydroxide to 60 ° C, 4-chlorophenol is melted, paraformaldehyde is suspended in it, and the reaction is stirred at 60 ~ 65 ° C for 1 h , the reaction solution was khaki and then purple-red, and the reaction mixture was stirred at about 65°C for 3.5h, the reactant was agglomerated, and the reaction was terminated; the agglomerated reaction mixture was dissolved in 100mL of hot methanol, and the Adjust the pH to about 2-3; cool to room temperature, precipitate 2,6-dimethylol-4-chlorophenol, filter and collect the product. It was recrystallized with methanol to obtain light khaki crystals. Yield 65%.
[0044] b. Preparation of 2,6-diformyl-4-chlorophenol
[0045] Add 3.8 g (0...
Embodiment 2
[0050] Embodiment 2, the preparation of anion acceptor organogel
[0051] Add 0.015 g of the above-prepared anion acceptor compound into 1 mL of DMF, heat to 70-120° C. to dissolve, form a DMF solution with a mass percentage of 1.5%, and form a stable anionic organic gel after cooling to room temperature.
Embodiment 3
[0052] Embodiment 3, detect anion with anion acceptor organogel
[0053] Take a small amount of anion acceptor organogels, place them on a white drip plate, and drop F on the organogels respectively. - , Cl - , Br - , I - , CH 3 COO - , HSO 4 - , H 2 PO 4 - , ClO 4- Anionic tetrabutylammonium salt in DMSO solution (0.01mol / L); organic gel changes from yellow to orange, then it is F-solution; organic gel changes from yellow to red, then it is CH 3 COO - solution; organogel changes from yellow to orange, then H 2 PO 4 - solution; if the organic gel does not change color, it is a solution of other ions.
