SnCl₂-catalyzed esterification of oleic acid with ethyl alcohol: catalyst recovery yields and substrate conversion^a [10].

Run	Recovery yields (%)	Oleic acid conversion (%)^b
1	90	92
2	87	87
3	90	92
4	91	91
5	90	91
6	89	89

^aReaction conditions: ethyl alcohol (120.0 mmol), Oleic acid (10.0 mmol), SnCl₂·2H₂O (0.1 mmol), 12 hours, and reflux temperature.
^bCalculated from the GC peaks areas of the ethyl oleate.
