Support influence on the basicity promotion of lithium-based mixed oxides for transesterification reaction

- Lithium containing oxides for catalytic transesterification.
- The support nature strongly affect the basicity promotion of the Li containing oxides.
- The Li addition onto the catalysts increases the base site number and strength.
- Li/MgO and Li/Mg(Al)O exhibited high activity under mild reaction conditions (313 K).
- The reaction occurs through heterogeneous/homogeneous mechanism.
