在Bronsted酸性离子液体1-甲基咪唑四氟硼酸盐（[Hmim]+ BF 4-）中，羧酸与醇的酯化反应可以进行。得到了良好的产率，并且生成的酯可以容易地从反应混合物中分离，而不需要任何挥发性有机溶剂。离子液体[Hmim]+ BF 4-经除水后可重复使用。
Esterification of carboxylic acids with alcohols could be carried out in a Bronsted acidic ionic liquid 1-methylimidazolium tetrafluoroborate ([Hmim]+BF4-). Good yields were obtained, and the esters produced could be easily separated from the reaction mixture without any volatile organic solvents. The ionic liquid [Hmim]+BF4- could be reused after removal of water.
