Abstract A highly efficient and eco‐friendly esterification was achieved by a series of novel dicationic acidic ionic liquids (DAILs) containing double SO 3 H cations. High yields of the product esters were obtained by using 2 mol% of the DAILs as catalysts and DAIL I could be reused at least ten times without appreciable loss of its efficicency.
