Common terminology of organic peroxides
organic peroxide
Liquid or solid organic substances containing a divalent OO-structure and can be regarded as derivatives of hydrogen peroxide whose one or two hydrogen atoms have been replaced by organic groups. The term also includes organic peroxide formulations (mixtures). Organic peroxides are substances or mixtures that can undergo exothermic self-accelerating decomposition and are thermally unstable. Additionally, they may have one or more of the following properties:
a) Explosive decomposition;
b) fast burning;
c) are sensitive to impact or friction;
d) dangerous reactions with other substances
Note: In laboratory tests, organic peroxides are prone to explosion, rapid deflagration or violent effects when heated under airtight conditions, and are considered to have explosive properties.
active oxygen
Refers to the expression of the oxidative power present in organic peroxides in the form of oxygen (when oxygen: 8.00)
Self-accelerating decomposition temperature (SADT)
The lowest temperature at which accelerated decomposition of peroxides begins in strong packaging suitable for storage and transport.
half life
The time required for organic peroxides to decompose 50% under specific temperature conditions.
Alarm temperature (Tem)
The temperature at which first aid measures must be taken (eg removal of organic peroxides). Obtained from the SADT.
Control temperature (Te)
The maximum temperature at which the product can be stored safely. Calculated from the SADT
