A new silica bonded N-(propylcarbamoyl)sulfamic acid (SBPCSA) catalyst has been prepared for the highly efficient synthesis of a series of acrylonitrile derivatives via solvent-free facile Knoevenagel condensation between differently substituted heterocyclic/aromatic aldehydes 1 (a–o) and 2-thiopheneacetonitrile (2). The catalyst was characterized by FT-IR, SEM-EDX and XRD techniques. The thermal stability
