Dicyclohexyl peroxydicarbonate(technically pure) Chemical Properties,Usage,Production

Chemical Properties

White solid powder. Melting point 44-46°C (content >97%). Decomposition temperature 42℃. Insoluble in water, slightly soluble in ethanol and aliphatic hydrocarbons, soluble in ketone, ester, soluble in aromatic solvents and chlorinated hydrocarbons. In contact with stabilizers, catalysts, desiccants and iron, copper and other metals, can accelerate its decomposition, insensitive to friction and impact.

Uses

Dicyclohexyl Peroxydicarbonate is a catalyst used in the frontal copolymerization in the presence of nano-particles.

General Description

Dicyclohexyl peroxydicarbonate(technically pure) is particularly sensitive to temperature rises. Above a given "Control Temperature" they decompose violently. They are generally stored or transported in a water slurry.

Reactivity Profile

DICYCLOHEXYL PEROXYDICARBONATE decomposes violently or explosively at temperatures 0-10°C owing to self-accelerating exothermic decomposition; Several explosions were due to shock, heat or friction; amines and certain metals can cause accelerated decomposition [Bretherick, 1979 p. 156].
