Hazard Predictions

• Explosive: Reaction products may be explosive or sensitive to shock or friction
• Flammable: Reaction products may be flammable
• Generates gas: Reaction liberates gaseous products and may cause pressurization
• Generates heat: Exothermic reaction at ambient temperatures (releases heat)
• Intense or explosive reaction: Reaction may be particularly intense, violent, or explosive
• Toxic: Reaction products may be toxic

Acetone will produce toxic haloforms if oxidized by metal hypohalites such as NaClO (Howard, W.L. 2001. Acetone. In Kirk-Othmer Encyclopedia of Chemical Technology. John Wiley & Sons, Inc. (Online)).

Acetone reacts explosively with difluorine dioxide, even at -78 C (Streng, A.G. 1963. Chemical Reviews 615).

Acetone ignites or explodes on contact with nitrosyl perchlorate (Hoffman, K.A. et al. 1909. Berichte. 42:2031).

CrO3 and ketones, including acetone and methyl ethyl ketone, ignite on contact (Fawcett, H.H. 1959. Industrial and Engineering Chemistry Research 51(4):90A; Mikhailov, V. 1960. Chemical Abstracts 54:23331f; Mellor, J.W. 1943. Mellor's Comprehensive Treatise on Inorganic and Theoretical Chemistry. Longmans, Green and Co Ltd. Volume 11. pp. 235).

Acetone forms explosive dimeric and trimeric peroxides with H2O2. One of the peroxides that can be formed is tricycloacetone peroxide (TCAP or TATP), an explosive that has recently become popular among terrorists (Anon. 1970. Agnew. Chem. (Nachr.) 18:3).

Many ketones, including acetone, methyl ethyl ketone, diethyl ketone, cyclopentanone, and cyclohexanone, form explosive peroxides with H2O2 in acidic solution, some of which are shock and friction sensitive (Bjorklund, G.J. et al. 1950. Trans. Royal Society of Canada, (Sect. III) 44:25).

Acetone forms explosive mixtures with hydrogen peroxide (Monger, J.M. et al. 1961. Journal Chemical and Engineering Data 6(1):23).

Acetone forms explosive mixtures with oxygen, and may spontaneously ignite combustible substances such as acetylene (CISCH. 1976. Chemical Safety Summary 47:33-34).

Methyl ethyl ketone may peroxidize when exposed to oxygen (Mageli, O.L., J.R. Koczynski. 1964. Encyclopedia of Polymer Science and Technology 9:831; Milas, N.A. 1959. Journal of the American Chemical Society 81:5824).

H2O2 will peroxidize methyl ethyl ketone (Beilstein. 1:688, 1(1):347, 1(2):726, 1(3):2770, 1(4):3243).

Acetone is violently reactive with oxidants (Lewis, R.J., Sr. 1992. Sax's Dangerous Properties of Industrial Materials, 8th Edition. New York: Van Nostrand Reinhold. pp. 23.) such as nitrosyl chloride (Kaufmann, G.B. 1957. Chemical and Engineering News 35(43):60.), chromium trioxide (Delhez, R. 1956. Chem. Ind. (London) 931), hydrogen peroxide (Seidl, H. 1964. Agnew. Chem. (International Edition, England) 3:640; 1964. Agnew. Chem. 76:716.), nitrosyl perchlorate, chromyl chloride, and thiotrithiazyl perchlorate (Lewis 23).

Acetone may ignite on contact with chromium trioxide (Delhez, R. 1956. Chemistry and Industry 931).
