摘要
近几年来,离子液体作为环境友好的绿色催化剂,广泛用于催化合成生物柴油中。综述了在催化合成生物柴油中离子液体催化剂的分类,即B酸性离子液体(磺酸基功能化B酸性离子液体和基于酸性阴离子的B酸性离子液体)、L酸性离子液体和新型B碱性离子液体,以及离子液体催化剂的合成方法和表征方法,同时阐述了离子液体催化剂在制备生物柴油过程中的应用及其反应机理,并对离子液体催化剂的发展进行了展望。
Ionic liquids as environmentally friendly catalysts were applied in biodiesel production. In this paper, the advances in the ionic liquids catalysts, namely B acidic ionic liquids with sulfonic acid groups or acidic anion groups, L acidic ionic liquids and new B basic ionic liquids, and their application in biodiesel production were reviewed. The synthesis and the characterization of the ionic liquids were summarized. The catalytic reaction mechanism of the ionic liquids in the biodiesel production was discussed. In addition, the prospect for the application of the ionic liquids to biodiesel production was also stated.
