Tin-Catalyzed Esterification and Transesterification Reactions: A Review
Figure 8
Effect of water on the SnCl2-catalyzed esterification of the FFA presents in the WCO samples with ethyl alcohola [23]. Reaction conditions: ethyl alcohol (380.0 mmol, 21.8 mL), waste cooking oil (13.0 g, 13.2 mL), SnCl2·2H2O (0.30 mmol), water initially added (0.0–5.0% wt.), reflux temperature.
