Abstract

Heats of ionization of barbituric acid and several substituted barbituric acids in aqueous solution have been determined calorimetrically at 298° K. Ionization constants have been determined for 5-allylbarbituric acid and 5-methylbarbituric acid. Entropies of ionization of all the acids investigated are calculated by combination of ΔG° values derived from ionization constants with our ΔH° values.
