N-butyl,methylpyrrolidinium bromide - Reference Information
| Introduction | 1-butyl-1-methylpyridinium bromide is an ionic liquid. Ionic liquid (ionic liquid) is a room temperature molten salt composed of organic cations and organic or inorganic anions. It has a wide liquid range, low vapor pressure, high thermal and chemical stability, adjustable physical and chemical properties, and electrochemical window Wide, good ionic conductivity, environmental friendliness and other special properties. |
| preparation | three layers of Nafion 902 cation exchange membrane are arranged in the electrolytic cell. the cation exchange membrane divides the electrolytic cell into a cathode chamber and an anode chamber, using PtO2 as the anode and graphite as the cathode, ethylene glycol aqueous solution with a concentration of 8mol/L was added to the anode chamber of the electrolytic cell as anolyte, and 10g N-methyltetrahydropyrrole and 8.7g n-butanol were added to the anode chamber. A mixed aqueous solution of acetonitrile with a content of 5wt% KBr was added to the cathode chamber of the electrolytic cell as a catholyte. Turn on the power supply, electrolyze with constant current for 2 hours under the conditions of electrolysis temperature of 50 ℃ and current density of 3A/dm2, take out catholyte after electrolysis, extract with 100ml xylene to obtain extract liquid, then wash with 100ml water, 50ml saturated sodium bicarbonate aqueous solution and 100ml water in sequence, dry and concentrate anhydrous sodium sulfate to obtain 1-butyl-1-methylpyridoxonium bromide ionic liquid. |
