摘　　要：液体酸催化剂在化学化工领域发挥巨大作用的同时伴随着分离回收困难、反应器腐蚀及废酸处理繁琐等明显缺点,寻求有潜在工业应用前景的替代型催化剂已成为当前催化领域的重要研究方向。磁性固体酸作为一种高效的新型多相催化剂,在提供酸催化能力的同时具有磁控分离的特性,符合绿色化学化工的发展理念,正在逐步取代液体酸发挥重大作用,是当前固体酸研究的热点之一。本文对不同制备方法、不同种类酸的磁性固体酸研究进行了综述,分析了各种方法的优缺点,阐述了磁性固体酸在催化领域的应用研究现状,并对磁性固体酸未来的研究方向作了展望。Liquid acids as homogeneous catalysts have been playing a major role in chemical-related processes, however simultaneously accompanied by the difficulty of separation and recovery, unfavorable conditions of reactor corrosion and waste acid treatment. In this sense, the exploration of alternative acid catalysts to meet the requirement of current chemical process is of great importance. Comparatively speaking, magnetic solid acids, combined with both properties of acceptable acidity and easy separation from reaction systems, are a new kind of promising heterogeneous catalyst and have being received more and more research interest. Within the context, the recent research advance in the various preparation methods towards magnetic solid acids, effectiveness of different synthesis pathways and the catalytic applications of magnetic solid acids in corresponding reactions are summarized. Meanwhile, the existing problems and the direction of future development of magnetic solid acids have also been outlined in this review.
