Hazard Predictions

• Corrosive: Reaction products may be corrosive
• Flammable: Reaction products may be flammable
• Polymerization hazard: Polymerization reaction may become intense and may cause pressurization

Under certain conditions, potassium hydride can catalyze the polymerization of dienes (Rittmeyer, P., U. Wietelmann. 2002. Hydrides. In Ullmann's Encyclopedia of Industrial Chemistry. Wiley-VCH Verlag GmbH & Co. KGaA. (Online)).

Organolithium compounds can initiate the polymerization of isoprene (Salzer, A. 2010. Organometallic Compounds. Ullmann's Encyclopedia of Industrial Chemistry. (Online)).

Organo-alkali metal compounds will reduce one double bond of conjugated dienes, resulting in an unsaturated metal alkyl compound with a metal-carbon bond allylic to a carbon-carbon double bond. These addition compounds are extremely strong bases and are potentially pyrophoric (Pascal, P. 1966. Nouveau Trait茅 de Chimie Min茅rale. Vol. 2, Part 2, p. 743. Masson et Cie.).

Lithium aluminum hydride can reduce conjugated dienes (Eggeman, T. 2001. Hydrides. In Kirk-Othmer Encyclopedia of Chemical Technology. John Wiley & Sons, Inc. (Online)).
