An organic compound that is having two oxygen atoms together is known as an organic peroxide. Organic peroxide undergoes self-accelerating decomposition and thus, result in rapid burning and explosive decomposition. Organic peroxide is available in various forms including solid, pastes or liquids. Few materials such as mineral spirits (odourless in nature), water and some of the phthalate esters do not react with organic peroxide. These materials are used to dilute organic peroxide. Diluted organic peroxides offer stability when exposed to physical shock or heat, as compared to the undiluted organic peroxides. Moreover, diluted organic peroxides are safer to handle, produce and use for further applications. In addition, organic peroxide is used as curing agent, high polymer initiator, cross-linking agent, accelerator, catalyst, hardener, activator and promoter. However, usage of activator and accelerator needs to be checked as these substances might result in accident, when mixed with organic peroxide.
