Unfortunately, a structure error appeared in my article (J. Chem. Educ. 1997, 74, 1055-1059). Structure 5 should have been methyl o-hydroxybenzoate (shown at right), and not the methyl p-hydroxybenzoate shown in the article. The boiling point given, 222 °C, is correct for methyl salicylate (methyl o-hydroxybenzoate) and this material is an oil under ambient conditions with a freezing point of -8.6 °C. Methyl p-hydroxybenzoate is a solid under ambient conditions with a melting point of 131 °C, a boiling point of 280 °C at 708 mm Hg, and no special flavor attributes.
