msds information

tert-butyl hydroperoxide usage and synthesis

chemical properties	colourless liquid (as an aqueous solution) with a sweet smell
general description	watery odorless colorless liquid. floats and mixes slowly with water.
air & water reactions	water soluble.
reactivity profile	most alkyl monohydroperoxides are liquid. the explosivity of the lower members (e.g., methyl hydroperoxide, or possibly, traces of the dialkyl peroxides) decreasing with increasing chain length and branching [bretherick 2nd ed. 1979 p. 10]. though relatively stable, explosions have been caused by distillation to dryness [milas, jacs 1946, 68, 205] or attempted distillation at atmospheric pressure [castrantas 1965 p. 15].
