p-Chlorobenzoyl peroxide Bis(p-ehlorobenzoyl)peroxide

Chemical properties

White, odorless powder. Decomposes violently on heating or contamination. Insoluble in water; soluble in organic solvents.

The Uses of p-Chlorobenzoyl peroxide Bis(p-ehlorobenzoyl)peroxide

Curing agent for silicone rubbers.

Definition

A mixture of 50% bis(p-chlorobenzoyl)peroxide in silicone fluid.

General Description

Odorless white solid or paste. Sinks in water.

Reactivity Profile

In pure crystalline form there is danger of explosion upon heating, shock, or friction. Peroxides 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.

Hazard

Dangerous fire and explosion risk, explodes when heated to 38C, strong oxidizer, will ignite on contact with organic materials. Store in dark, cool locality. Toxic.

Health Hazard

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

Safety Profile

Moderately toxic byintraperitoneal route. Probably an irritant to skin andmucous membranes. Dangerous fire hazard; a powerfuloxidizer. Store in a cool place away from fire hazards,sparks, open flames, and out of the direct rays of the sun.Dangerous e

Carcinogenicity

The only other data available for this organic peroxide show that it had no effects on tumor cells when injected intraperitoneally at 125mg/kg in the chest wall of mice .
