Catalytic synthesis of n-butyl carboxylate with immobilized ionic liquid based on response surface methodology optimization.

ABSTRACT: Four kinds of functional ionic liquids (ILs) ([C₃SO₃Hnmp]HSO₄), 1-(3-sulfopropyl)-1-methylpyrrolidone phosphate ([C₃SO₃Hnmp]H₂PO₄), 1-(3-sulfopropyl)-1-methylpyrrolidone p-toluene sulfonate ([C₃SO₃Hnmp]CH₃SO₃H) and 1-(3-sulfopropyl)-1-methylpyrrolidone methyl sulfonate ([C₃SO₃Hnmp]C₆H₆SO₃H)) were prepared and the catalytic activity of these ILs during esterification of carboxylic acids (formic acid, acetic acid, propionic acid, butyric acid) with alcohols was investigated. The results indicated that the IL ([C₃SO₃Hnmp]HSO₄) exhibited an optimal catalytic performance. And then the IL (
