Determination of Content of N-Butyl Pyridine Tetrafluoroborate in Ethanol by UV-Spectrum

Abstract:

N-butyl-pyridine tetrafluoroborate is prepared by the double decomposition reaction of BPC and NaBF₄. The ionic liquid at room temperature used in the experiment has a significant absorption determined by UV spectrum within the range of 200-400nm, the maximum absorption wavelength of BP-BF₄ ionic liquid in ethanol is 259nm. The standard working curve of BP-BF₄ ionic liquid is y=0.03299x+0.02314 (R=0.99908). The linear range of BP-BF₄ ionic liquids in the ethanol is 1-75 mg/L.The recovery rate of BP-BF₄ ionic liquid which is between 99.2% and 103.4%, is measured by standard addition method in ethanol.
