SCHEDULED MAINTENANCE
The ionization of acetylacetone in water can be regarded as two separate processes, (1) enolization, (2) ionization. The heat of the overall process has been measured. ΔHT=+3·549 ± 0·005 kcal./mole. Values of ΔG, ΔH, and ΔS for processes (1) and (2) have been derived. The heat of the overall process in 50% water–dioxan has also been determined; ΔH=+2·95 ± 0·04 kcal./mole.
