Embodiment 1
[0017] Embodiment 1N-butylpyridine perrhenate ([BPy][ReO 4 ]) ionic liquid
[0018] The preparation method is as follows:
[0019] Take a certain amount of purified N-butylpyridine, add 2 to 4 times of deionized water to dissolve it, add it to OH type anion exchange resin for ion exchange, collect the outflowing solution until bromide ion is detected. Perform an accurate titration with hydrochloric acid of known concentration to calculate the concentration of the collected solution. Add it to the ammonium perrhenate aqueous solution, the molar ratio is 1:1, heat and stir at 70°C for 4 hours, remove the water by rotary evaporation, add excess anhydrous methanol and acetonitrile solution with a volume ratio of 1:9 after cooling , sealed and vigorously stirred, placed at -34°C for 12 hours, distilled under reduced pressure to remove methanol and acetonitrile, and dried the obtained product in a vacuum oven at 80°C for 48 hours. The resulting product is N-butylpyridine perrhena...
Embodiment 2
[0020] Embodiment 2N-Propylpyridine perrhenate ([TPy][ReO 4 ]) ionic liquid
[0021] The preparation method is as follows:
[0022] Take a certain amount of purified N-propylpyridine, add 2 to 4 times of deionized water to dissolve it, add it to OH type anion exchange resin for ion exchange, and collect the outflowing solution until bromide ion is detected. Perform an accurate titration with hydrochloric acid of known concentration to calculate the concentration of the collected solution. Add it to the ammonium perrhenate aqueous solution with a molar ratio of 1:2, heat and stir at 65°C for 4 hours, remove the water by rotary evaporation, and add excess anhydrous methanol and acetonitrile solution with a volume ratio of 1:9 after cooling , sealed and vigorously stirred, placed at -34°C for 12 hours, distilled under reduced pressure to remove methanol and acetonitrile, and dried the obtained product in a vacuum oven at 80°C for 48 hours. The resulting product is N-butylpyrid...
Embodiment 3
[0023] Embodiment 3N-ethylpyridine perrhenate ([EPy][ReO 4 ]) ionic liquid
[0024] The preparation method is as follows:
[0025] Take a certain amount of purified N-ethylpyridine, add 2 to 4 times of deionized water to dissolve it, add it to an OH-type anion exchange resin for ion exchange, and collect the outflowing solution until bromide ions are detected. Perform an accurate titration with hydrochloric acid of known concentration to calculate the concentration of the collected solution. Add it to the ammonium perrhenate aqueous solution, the molar ratio is 1:1.5, heat and stir at 60°C for 4 hours, remove the water by rotary evaporation, add excess anhydrous methanol and acetonitrile solution with a volume ratio of 1:9 after cooling , sealed and vigorously stirred, placed at -30°C for 12 hours, distilled under reduced pressure to remove methanol and acetonitrile, and dried the obtained product in a vacuum oven at 80°C for 48 hours. The resulting product is N-butylpyridi...
