磺酸型硅基固体酸制备及应用的研究进展

Review on preparation and application of silica-functionalized sulfonic solid acid

随着绿色化学的发展,将磺酸基团负载到固体表面制备磺酸型固体酸代替传统的硫酸催化剂越来越受到了人们的关注。为此,综述了磺酸型硅基固体酸的制备方法及应用,介绍了浸渍、接枝和共缩合3种制备方法,探讨了固体酸在酯化、醚化、脱水等反应中的催化活性。

With the development of green chemistry,sulfonic acid group loading to solid surface to prepare sulfonate solid acid instead of traditional sulfuric acid catalyst is getting more and more attention.The preparation methods and application of silica-functionalized sulfonic solid acid catalysts were reviewed,and the three methods including impregnation,grafting and co-condensation were presented.The catalytic activity of sulfonate solid acid in the esterification,etherification,dehydration and so on was discussed.
