Debenzylation of vanillic acid over sulfosuccinic acid functionalized mesoporous silica nanocomposites
•Sulfosuccinic acid functionalized ordered mesoporous silica was synthesized and characterized for the first time.•Liquid phase debenzylation of vanillic acid showed very high selectivity of the product.•Plausible reaction mechanism was explained.
Sulfosuccinic acid functionalized mesoporous silica (SBA/SSA) was synthesized and characterized for debenzylation of vanillic acid in liquid phase for the first time. The catalytic activity studies showed high activity (82%) and selectivity (96%) for the desired product vanillic acid over SBA/SSA compared to 74% selectivity over silica/SSA. Synergistic effects of acidic/basic groups responsible for higher activity and selectivity were explained with plausible mechanism.
