GPS Safety Summary Substance Name: Methyl Ethyl Ketone Peroxide 1. General Statement Methyl ethyl ketone peroxide is an organic peroxide commercially available as a 40% to 60% solution. 2. Chemical Identity Name: 2-Butanone, peroxide Brand names of mixtures: Luperox® K1S, Luperox® K10, Luperox® K18, Luperox® K1G, Luperox® K12G Chemical name (IUPAC): Reaction mass of butane-2,2-diyl dihydroperoxide and di- sec-butylhexaoxidane CAS number(s): 1338-23-4 List number: 700-954-4 Molecular formula (optional): Mixture of C H O and C H O 4 10 4 8 18 6 Structure (optional): 3. Use and applications Methyl ethyl ketone peroxide is an unstable organic peroxide used in the manufacture of unsaturated polyester resins. 4. Physical / Chemical properties Methyl ethyl ketone peroxide (MEKP) is a mixture of isomers (monomer and dimer) and is marketed exclusively with various stabilizing agents that cannot be totally separated due to the explosive properties of the substance. Organic peroxides are thermally unstable substances or mixtures, which can undergo exothermic self-accelerating decomposition.
