 Methyl isobutyl ketone peroxide (CAS NO.37206-20-5) is a colorless liquid shipped with not more than 62% peroxide in solution of methyl isobutyl ketone. It crystallizes when dry. May explode from heat, shock or friction when dry. Peroxides, such as Methyl isobutyl ketone peroxide (CAS NO.37206-20-5) (in solution,content≤62%,with type A thinner), are good oxidizing agents. Organic compounds can ignite on contact with concentrated peroxides. Strongly reduced material such as sulfides, nitrides, and hydrides may react explosively with peroxides. There are few chemical classes that do not at least produce heat when mixed with peroxides. Many produce explosions or generate gases (toxic and nontoxic). Generally, dilute solutions of peroxides (<70%) are safe, but the presence of a catalyst (often a transition metal such as cobalt, iron, manganese, nickel, or vanadium) as an impurity may even then cause rapid decomposition, a buildup of heat, and even an explosion. Solutions of peroxides often become explosive when evaporated to dryness or near-dryness. May explode from heat or contamination. May explode from heat, shock, friction or contamination. May ignite combustibles (wood, paper, oil, clothing, etc.). May be ignited by heat, sparks or flames. May burn rapidly with flare-burning effect. So the storage environment should be ventilate, low-temperature and dry. Keep Methyl isobutyl ketone peroxide (CAS NO.37206-20-5) separate from organic matter, restore objects, flammable, strong acid.
