Heterogeneous Tin Catalysts Applied to the Esterification and Transesterification Reactions
Figure 3
Reusability of the Fe2O3-doped sulfated tin oxide catalyst for the lauric acid esterification and triacetin transesterification reactions after 8 hours reaction per cycle [25]. (Reaction conditions: transesterification (0.25 g of catalyst, 5.675 g of triacetin, and 7.5 g of methanol, 8 h); esterification (0.16 g of catalyst, 4.167 g of lauric acid, and 10 g of methanol, 6 h); 60°C temperature in both reactions.)
