摘　　要：制备了两种基于4-二甲氨基吡啶(DMAP)的、对水和空气稳定的、带—SO3H官能团的Brnsted酸离子液体,它们具有高的催化活性、很好的稳定性、可以循环使用、对环境友好,用于催化十三烷二酸与醇反应制备一系列二元酸酯,收率达到80%,二元酸酯选择性达到100%,且催化剂易与产物二元酸酯分离。Two moisture-stable with an alkane sulfonic acid group Bronsted-acidic ionic liquids based on DMAP were prepared. A series of diesters were prepared by tridecanedioic acid with alcohols in these ionic liquids. These alkane sulfonic acid group ionic liquids showed good catalytic activity, with the product yield reaching 80% and selectivity equating to 100%. The produced ester can be separated via simple decantation, and the ionic liquids can be reused several times. These stable, eco-friendly ionic liquids are ideal catalysts for esterification.
