The intermediate of the room temperature ionic liquid,N-butylpyridium chloride was prepared by reaction of N-butylchloride and pyridine. The RTIL of N-butylpyridium fluoroborate was synthesized in acetone. BPC-BF4 ionic liquid content in methanol is measured by UV-spectrum. The maximum absorption wavelength was 259nm and the absorption shows linear relation with concentration between 200～400nm with the correspondence coefficient of 0.99567. The recovery rates were was between 99.9% and 100.3%.
