Heterogeneous catalysts for biodiesel evolution. Compared to solid acid, solid base offers a faster rate to transesterification down mild condition. The hydrotalcite was tested in transesterification rebound of economic soybean oil with anhydrous methanol. The reactions were the out at atmospheric pressure, in a batch dandify reactor with a capacity of 50 mL, under magnetic stirring, connected to a condenser. The experiments were the out at a temperature of 64 °C (337 K) with 5 % (weight basis) of catalyst consolidation varying the molar ratio (MR) methanol/ oil and reaction time as show.
