Abstract: The catalytic activity of hydrotalcite (as-synthesized and calcined) of varying Mg/Al molar ratio (1.5-5) has been studied for the addition reaction of carbon dioxide to propylene oxide in the presence of the solvent, DMF. The calcined samples show higher activity than the as-synthesized samples. The reaction temperature has been optimized and the activation energy of the reaction calculated using Arrhenius plot in the presence and absence of calcined hydrotalcite samples with DMF as solvent. The calcined hydrotalcite minimizes the activation energy of cycloaddition reaction in the presence of DMF by 10 kJ/mol. Higher TON (307 mmol/gcat) is obtained at higher rato of propylene oxide:catalyst. The possible reaction mechanism is proposed for the reaction.
