2,5-DIMETHYLHEXANE-2,5-DIHYDROPEROXIDE Chemical Properties,Usage,Production

General Description

White wet solid. May float or sink in water. 2,5-DIMETHYLHEXANE-2,5-DIHYDROPEROXIDE is particularly sensitive to temperature rises. Above a given "Control Temperature" they decompose violently. 2,5-DIMETHYLHEXANE-2,5-DIHYDROPEROXIDE is generally stored or transported in a water slurry.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Peroxides, such as 2,5-DIMETHYL-2,5-DIHYDROPEROXY HEXANE, 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. Decomposes in contact with many metals and acids [USCG, 1999].

Health Hazard

Contact with eyes or skin causes irritation.

Fire Hazard

Behavior in Fire: Decomposes violently when heated in fire. Can increase intensity of fire when in contact with combustible material. Containers may explode.
