Sulfonic acid functionalised SBA-15 as catalysts for Beckmann rearrangement and esterification reaction

摘要

Hybrid inorganic-organic solid acid materials SBA-15-Ph-SO3H were synthesized by the directly co-condensation method under the acid medium. The resulting materials perform well both in the liquid phase Beckmann rearrangement (The yield is 32.3%) and esterification reaction (The yield is 95.5%). And more, the catalysts show the different catalytic performance in these two reactions.
