Dicetyl peroxydicarbonate Chemical Properties,Usage,Production

Chemical Properties

Dicetyl peroxydicarbonate is a white powder with faint odor. It presents a bulk density of 0.6 g/cm³ andmelting point of 52°C. It is sensitive to heat and its storage must be done so with stringent temperature control measures. Its explosion hazard is mitigated by mixing the peroxide with inert solid. It decomposes violently or explosively at temperatures 0–10°C owing to self-accelerating exothermic decomposition. Several recorded explosions were due to shock, heat, or friction; amines and certain metals can cause accelerated decomposition (12d).

Uses

Dicetyl peroxydicarbonate is an imitator for the copolymerization of vinyl chloride, vinylidene chloride, acrylates, and methacrylates. No information was located for this compound. Decomposition or combustion products include carbon dioxide, carbon monoxide, and hexadecanol.

General Description

Dicetyl peroxydicarbonate is sensitive to heat. Storage of Dicetyl peroxydicarbonate must be done so with stringent temperature control measures. It's explosion hazard is also mitigated by mixing the peroxide with inert solid.

Reactivity Profile
