Dissociation Constants:pKa = 8.93
Experimental Properties:Specific gravity: 0.9753 at 20 °C/20 °C|Heat of solution: -11.5 Btu/lg = -6.4 cal/g; Ratio of specific heats of vapor (gas) = 1.072 (est)|The enol form predominates (70-90%) in the pure liquid state, the vapor state, and when dissolved in most organic solvents. In water, only 12% of the enol is present at equilibrium|Hydroxyl radical reaction rate constant = 9.05X10-11 cu cm/molec-sec at 25 °C (enol-form)
Air and Water Reactions:Highly flammable. Soluble in water.
Reactive Group:Ketones
Reactivity Alerts:Highly Flammable
Reactivity Profile:Ketones, such as PENTANE-2,4-DIONE, are reactive with many acids and bases liberating heat and flammable gases (e.g., H2). The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4. May dissolve plastics (USCG, 1999).
Autoignition Temperature:644 °F (USCG, 1999)|644 °F (340 °C)|340 °C
Heat of Combustion:-11,070 Btu/lb = -6,150 cal/g = -257X10+5 J/kg
Physical Dangers:The vapour is heavier than air.
Heat of Vaporization:36.55 kJ/mol at 101.3 kPa
