Distillation is the most suitable method for separating isobutyl oleate from oleic acid. Isobutyl oleate, an ester, has a lower boiling point than oleic acid, a carboxylic acid. Careful distillation under reduced pressure would allow the separation of isobutyl oleate as the distillate, leaving oleic acid behind in the distillation flask.
