Heterogeneous Tin Catalysts Applied to the Esterification and Transesterification Reactions
Figure 11
Conversion of oleic acid obtained with the fresh and used /SnO2-0.3–773 K catalyst during the esterification reaction with ethanol [31]. (Reaction conditions: ethanol : oleic acid molar ratio is equal to 1 : 10, 353 K, 4 h.)
