Cyclohexanone peroxide Chemical Properties,Usage,Production

Chemical Properties

This peroxide is an off-white thick paste .

Uses

1-Hydroperoxy-1＇-hydroxydicyclohexyl Peroxide is used as a catalyst for hardening certain fiberglass resins.

General Description

Odorless thick white liquid. Sinks in water.

Reactivity Profile

Peroxides, such as Cyclohexanone peroxide, 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 ignite combustibles (wood, paper, oil, clothing, etc.). May be ignited by heat, sparks or flames. May burn rapidly with flare-burning effect. Behavior in Fire: May explode [USCG, 1999].

Health Hazard

Irritates eyes and skin on contact. Ingestion causes irritation of mouth and stomach.

Fire Hazard

Behavior in Fire: May explode

Safety Profile

Slightly toxic by parenteral route. A severe eye and skin irritant. When heated to decomposition it emits acrid smoke and irritating vapors.
