| 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. |
