| Popis: |
N-heptyl-pyridine tetrafluoroborate is prepared by the double decomposition reaction of HEPB 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 HEP-BF4ionic liquid in ethanol is 244nm. The standard working curve of HEP-BF4ionic liquid is y=0.00441+0.01563x (R=0.99912). The linear range of HEP-BF4ionic liquids in the ethanol is 1-75 mg/L. The recovery rate of HEP-BF4ionic liquid which is between 96.6% and 102%, is measured by standard addition method in ethanol. |
