Embodiment 1
[0034] This example illustrates the method of using 1-butyl-3-methylimidazolium hexafluorophosphate to prepare surface amphiphilic nanometer iron sulfide hydrogenation catalyst.
[0035]Add a certain amount of iron stearate to 500mL deionized water, so that the concentration of iron reaches 0.015mol / L, and stir until uniform; add ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate to the above mixture, Make 1-butyl-3-methylimidazolium hexafluorophosphate: ferric stearate (molar ratio) reaches 18:1, stir until uniform, add potassium sulfide aqueous solution in above-mentioned mixture, make potassium sulfide: potassium ferrite ( Molar ratio) reached 4:1, stirred until uniform, reacted at 40°C for 24h, and configured as an initial reaction mixture; transferred the initial reaction mixture to a high-pressure synthesis kettle, and crystallized at 180°C for 10h. After the crystallization is completed, the reactant is cooled to room temperature, filtered, washed with deioniz...
Embodiment 2
[0038] This example illustrates the method of using 1-ethyl-3-methylimidazolium tetrafluoroborate to prepare surface amphiphilic nanometer iron sulfide hydrogenation catalyst.
[0039] Add a certain amount of ferric nitrate to 500mL deionized water, so that the concentration of iron reaches 0.01mol / L, and stir until uniform; add ionic liquid 1-ethyl-3-methylimidazolium tetrafluoroborate to the above mixture, so that 1-ethyl-3-methylimidazolium tetrafluoroborate: ferric nitrate (molar ratio) reaches 24:1, stir until uniform, add sodium sulfide aqueous solution to the above mixture to make sodium sulfide: ferric nitrate (molar ratio) To reach 2.5:1, stir until uniform, react at 80°C for 12h, configure the initial reaction mixture; transfer the initial reaction mixture to a high-pressure synthesis kettle, and crystallize at 200°C for 4h. After the crystallization is completed, the reactant is cooled to room temperature, filtered, washed with deionized water and dried to obtain a ...
Embodiment 3
[0041] This example illustrates the method of using N-butylpyridine tetrafluoroborate to prepare surface amphiphilic nanometer iron sulfide hydrogenation catalyst.
[0042] Add a certain amount of ferric chloride to 500mL deionized water to make the concentration of iron reach 0.5mol / L, and stir until uniform; add ionic liquid N-butylpyridine tetrafluoroborate to the above mixture to make N-butyl Pyridine tetrafluoroborate: ferric chloride (molar ratio) reaches 10:1, stir until uniform; add potassium sulfide aqueous solution to the above mixture, make potassium sulfide: ferric chloride (molar ratio) reach 4:1, stir until Uniform, react at 95°C for 0.5h, configure the initial reaction mixture; transfer the initial reaction mixture to a high-pressure synthesis kettle, and crystallize at 100°C for 180h. After the crystallization is completed, the reactant is cooled to room temperature, filtered, washed with deionized water and dried to obtain a surface amphiphilic nano-iron sulfi...
