Dicumyl peroxide is an organic compound with the formula (C6H5CMe2O)2 (Me = CH 3). Classified as a dialky peroxide, it is produced on a large scale industrially for use in polymer chemistry. It serves as an initiator and crosslinking agent in the production of low density polyethylene. [2]
The lowest temperature at which a packaged organic peroxide will undergo a self-accelerating decomposition within a week is defined as the self-accelerating decomposition temperature (SADT). A large fire at the Arkema Chemical Plant in Crosby, Texas (USA) in 2017 was caused by the decomposition of various organic peroxides following power ...
Advanced oxidation processes (AOPs), in a broad sense, are a set of chemical treatment procedures designed to remove organic (and sometimes inorganic) materials in water and wastewater by oxidation through reactions with hydroxyl radicals (·OH). [1] In real-world applications of wastewater treatment, however, this term usually refers more ...
The self-accelerating decomposition temperature (SADT) is the lowest temperature at which an organic peroxide in a typical vessel or shipping package will undergo a self-accelerating decomposition within one week. [1] The SADT is the point at which the heat evolution from the decomposition reaction and the heat removal rate from the package of ...
Cumene hydroperoxide is an intermediate in the cumene process for producing phenol and acetone from benzene and propene. Cumene hydroperoxide is a free radical initiator for production of acrylates. [5] Cumene hydroperoxide is involved as an organic peroxide in the manufacturing of propylene oxide by the oxidation of propylene.
Spontaneous oxidation by oxygen at normal temperature. Autoxidation (sometimes auto-oxidation) refers to oxidations brought about by reactions with oxygen at normal temperatures, without the intervention of flame or electric spark. [1] The term is usually used to describe the gradual degradation of organic compounds in air at ambient temperatures.

In situ chemical oxidation. In situ chemical oxidation (ISCO), a form of advanced oxidation process, is an environmental remediation technique used for soil and/or groundwater remediation to lower the concentrations of targeted environmental contaminants to acceptable levels. ISCO is accomplished by introducing strong chemical oxidizers into ...
