Abstract

Heats of ionization of o-hydroxybenzaldehyde, m-hydroxybenzaldehyde, p-hydroxybenzaldehyde, vanillin, isovanillin and o-vanillin have been determined calorimetrically at 298° K. Entropies of ionization of these acids in aqueous solution have been calculated from these heats and free energies derived from ionization constants. The thermodynamic data are discussed briefly.
