n-Butyl Acetate Synthesis in the Presence of Pyridinium-Based Acidic Ionic Liquids: Influence of the Anion Nature

n-Butyl Acetate Synthesis in the Presence of Pyridinium-Based Acidic Ionic Liquids: Influence of... acidic ionic liquids: pyridinium hydrogen sulfate ([H– + − Pyr] [HSO ] ), pyridinium dihydrogen phosphate ([H– + − + − Pyr] [H PO ] ) and pyridinium nitrate ([H–Pyr] [NO ] ) 2 4 3 in the esterification of acetic acid with n-butanol was com- pared in the current paper. The alteration in the values of acetic acid conversion and esterification rate were inves- tigated as a function of the process parameters: catalyst nature, catalyst loading, initial molar ratio n-butanol:acetic acid and reaction temperature. The anion variety modi- fied the acidity of the obtained samples and effected + − their catalytic activity as follows: [H–Pyr] [NO ] < [H– + − + − Pyr] [H PO ] < [H–Pyr] [HSO ] .
