Luft- und Wasserreaktionen:Highly flammable. Soluble in water.
Reaktive Gruppe:Ketones
Reaktivitätsalarme:Highly Flammable
Reaktivitäts-Profil:Ketones, such as 3-METHYLBUTAN-2-ONE, 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 %2B H2O2, and HClO4.
Selbstentzündungstemperatur:1.8 °F|475 °C
Ionisationspotential:9.32 eV
Explosionsgrenze:Lower limit 9.0 °F; Upper limit 0.85 °F|Combustible Liquid
Physische Gefahren:The vapour is heavier than air and may travel along the ground; distant ignition possible. The vapour mixes well with air, explosive mixtures are easily formed.
