Procedure
In a third example, a three-compartment cell was constructed using a anode, a cation exchange membrane, an anion exchange membrane, and a cathode. 3 Liters of a 2 M solution of 1-butyl-3-methylimidazolium chloride was added to the first compartment, and 3 liters of a 3 M solution of HNO3 was added to the second compartment, and 0.5 liters of 1 M KOH was added to the third compartment. Electricity was applied to the cell, until the pH of the nitric acid-containing solution had risen to 7.0, whereupon the electrolysis was stopped and the second solution was removed from the cell. 85% BMIM Chloride was added continuously to the first compartment to maintain a concentration of 2 M in that compartment during the electrolysis. The second solution was passed through a weakbase ion exchange resin to remove residual nitric acid, then evaporated under rotary vacuum. The product, 1-butyl-3-methylimidazolium nitrate was obtained in 51% yield and contained 418 ppm potassium, 852 ppm chloride,and 3.24% water.
