| Abstract: | The
catalytic activity of synthetic hydrotalcites of varying Mg/Al molar ratio from
2 to 5 has been investigated for the transesterification of propylene carbonate
with methanol. The hydrotalcite with Mg/Al molar ratio of 5 at different
calcination temperature has been characterized using FT-IR, P-XRD and surface
area analyses. Under optimized conditions, the catalyst with Mg/Al molar ratio
5 shows highest propylene carbonate conversion (72 %) with 97 % dimethyl
carbonate selectivity. The catalyst shows the highest TON (280 mmol DMC/gcat)
ever reported with heterogeneous catalysts.
A plausible reaction mechanism has been proposed based on the results obtained. |
