UV-Spectrum Analysis of N-Octyl Pyridine Tetrafluoroborate in Ethanol

Abstract:

Ionic liquids have been attracting extraordinary attention for their unique properties, such as high ionic conductivity, negligible vapor pressure, and high thermal and electrochemical stability, which have made their varied applications in organic chemistry, material science, chemical engineering, physical chemistry, analytical chemistry and biotechnology. N-octyl-pyridine tetrafluoroborate is prepared by the double decomposition reaction of OPB 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 OP-BF4 ionic liquid in ethanol is 243nm. The standard working curve of OP-BF4 ionic liquid is y=0.0322+0.01542X (R=0.99962). The linear range of OP-BF4 ionic liquids in the ethanol is 1-75 mg/L. The recovery rate of OP-BF4 ionic liquid which is between 96.8% and 101%, is measured by standard addition method in ethanol.
