Air and Water Reactions:The neat chemical may be sensitive to prolonged exposure to air and light. Insoluble in water.
Reactive Group:Ketones
Reactivity Profile:Ketones, such as 1,2-NAPHTHOQUINONE, 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.
