<p>To achieve better selectivity of multiproduct conversion, syringic acid (SA) functionalized ordered mesoporous silica nanocomposites were synthesized and characterized via post grafted in-situ polymerization method for the liquid phase esterification of methacrylic acid with epichlorohydrin under environmentally friendly conditions. The physicochemical characterization results (PXRD, N₂-adsorption desorption isotherm, SEM etc.) revealed the presence of mesoporous nature of the samples. The synthesized nanocomposites were then used as catalysts for the liquid phase esterification of methacrylic acid (MAA) with epichlorohydrin (ECH) to achieve high selectivity of the products. Exceptionally, higher activity and selectivity of the desired products could be achieved for optimized experimental conditions. Finally, the plausible mechanism is also proposed and explained for the formation of products.</p>
