摘要：
Bronsted acidic ionic liquids (ILs) have been synthesized and investigated as catalysts in esterification and transesterification reactions: simple and non-corrosive salts characterized by aliphatic cations associated with an "acidic" anion (in particular, [HSO4](-)) gave the higher yields. A quite good correlation between IL acidity (H-0) and catalytic ability was found although also the hydrophilic nature of the ionic medium probably affects the process efficiency.
