| Chemical Properties | Dicumyl peroxide is a crystalline solid that melts at 42°C. It isinsoluble in water and soluble in vegetable oil and organicsolvents . It is used as a high-temperature catalyst inproduction of polystyrene plastics. The deflagration hazardpotential of this peroxide was tested using 5 g of igniter in therevised time–pressure test, but no pressure rise was produced. Noller et al. found it to be an intermediate firehazard. |
| Uses | Dicumyl peroxide(DCP) is used: in vulcanization of rubber as a crosslinking agent in the synthesis of polylactic acid composite fibers in the preparation of polyethylene composites in the synthesis of polyamide 112/ethylene vinyl acetate copolymer blends. |
| General Description | Dicumyl peroxide is a pale yellow to white granular solid with a characteristic odor. It is used as a polymerization catalyst and vulcanizing agent. |
| Reactivity Profile | The explosive instability of the lower dialkyl peroxides (e.g., dimethyl peroxide) and 1,1-bis-peroxides decreases rapidly with increasing chain length and degree of branching, the di-tert-alkyl derivatives being amongst the most stable class of peroxides. Though many 1,1-bis-peroxides have been reported, few have been purified because of the higher explosion hazards compared with the monofunctional peroxides. Dicumyl peroxide is unlikely that this derivative would be particularly unstable compared to other peroxides in it's class, Bretherick 2nd ed., p 44 1979. |
| Flammability and Explosibility | Non flammable |
| reaction suitability | reagent type: oxidant |
| Safety Profile | Mildly toxic by ingestion. See also PEROXIDES. When heated to decomposition it emits acrid smoke and irritating fumes. |
| Purification Methods | Crystallise the peroxide from 95% EtOH (charcoal). Store it at 0o. Potentially EXPLOSIVE. [Beilstein 6 IV 3220.] |
| Toxics Screening Level | The initial threshold screening level (ITSL) for dicumyl peroxide will remain 0.1 μg/m3 (annual averaging time). |
