1-（4-sulfonic acid） butyl-pyridinium was synthesized from 1,4-butanesuhone and pyridine. Then, ionic liquid was prepared from 1-（4-sulfonic acid ） butyl-pyridinium hydrosulfate and concentrated sulfuric acid. The effects of reaction temperature, reaction time and the solvent on the yield were studied. The optimal reaction condition was as follows： the yield of l-（4-sulfonic acid） butyl-pyridinium was higher in the absence of solvent,and the yield was 63.2% at 40 ℃ for 30 h. The total yield of ionic liquid was 62.5% and purity was over 95% at 80 ℃ for 8 h by solventless method.
