Hazard Predictions

• Explosive: Reaction products may be explosive or sensitive to shock or friction
• Flammable: Reaction products may be flammable
• 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

Halocarbons can react exothermically, and sometimes explosively with aluminum. Reactions may evolve toxic HCl gas (Urben, P.G. 1995. Bretherick's Handbook of Reactive Chemical Hazards, 5th Edition. Oxford: Butterworth-Heinemann. pp. 27-30).

CCl4 and other chloromethanes are explosively reactive with aluminum (Stern, M., H.H. Uhlig. 1953. Journal of the Electrochemical Society 100:543), as are chlorobenzenes (Krishnamurti, R. 2003. Chlorinated Benzenes. In Kirk-Othmer Encyclopedia of Chemical Technology. John Wiley & Sons, Inc. (Online)).

Beryllium forms impact-sensitive mixtures with carbon tetrachloride or trichloroethylene (Armed Services Explosive Safety Board. 1968. Potential Incidents Report 39).

Methyl bromide can form potentially pyrophoric organometallics with aluminum, magnesium, or zinc (Ioffe, D., A. Kampf. 2003. Bromine, Organic Compounds. In Kirk-Othmer Encyclopedia of Chemical Technology. John Wiley & Sons, Inc. (Online)).

Mixtures of zinc and carbon tetrachloride are flammable (Berger, E. 1920. Compt. Rend. 170:29).

Magnesium forms flammable mixtures with finely divided polytetrafluoroethylene (Anon. 1969. Indust. Res. (9):15).

Titanium and trichloroethylene can spark if subject to impact (Armed Services Explosive Safety Board. 1968. Potential Incidents Report 39).

Reactions between powdered aluminum and dichloromethane may proceed violently (Piotrowski, A.M. et al. 1988. Journal of Organic Chemistry 53:2829-2935).

Grignard reagents are produced by the reaction of alkyl and aryl bromides and chlorides with metallic magnesium. These products are pyrophoric and will react violently with water or air (Loudon, Marc. 2002. Organic Chemistry. 4th ed. New York: Oxford University Press. p. 334-336).
