Synthesis of Starch Derived Sulfonated Carbon-based Solid Acid as a Novel and Efficient Nanocatalyst for the Synthesis of Dihydropyrimidinones

Novel Carbon-based solid-acid nanocatalyst (SCP-SO3H) has been synthesized via one-step hydrothermal carbonization and sulfonation of starch, citric acid, and p-toluenesulfonic acid at 180 °C in a sealed autoclave. The novel nanocatalyst had an acidity of 6.4 mmol/g which was characterized by IR, ED...
