REACTIVITY
Reactions of ketones such as methyl ethyl ketone with nonoxidizing
mineral acids, caustics, cyanides, mercaptans, or
other organic sulfides typically produce heat, while those
with alkali or alkaline earth elemental metals, nitrides or
strong reducing agents evolve heat and flammable gases. Reactions
with oxidizing mineral acids or other strong oxidizing
agents may generate heat and fire. Those with azo or
diazo compounds or hydrazines may generate heat and usually
innocuous gases. Reactions with organic peroxides or hydroperoxides
typically result in explosions. Various manufacturers
list oxidizing agents, chlorinated hydrocarbons in
the presence of alkalies, alkanolamines, amines, pyridines,
ammonia, caustics, inorganic acids, isocyanates, and halogens
as incompatible materials (505,507,511).
