Organic peroxides can be used as initiators and catalysts for polymerization of synthetic resins. In the field of polymer materials, Organic peroxides can be used as initiators, cross-linking agents, curing agents, regulators, etc. Now peroxides can be used in many fields and are very popular. What are the common Organic peroxides and what are their characteristics.
1. Peracetic acid
Peracetic acid is a colorless and strongly odorous liquid produced by the reaction of acetic acid and hydrogen oxide in the presence of sulfuric acid. It is very unstable, as long as the temperature is slightly higher, it will decompose into hydrogen gas and explode. Generally, pure acetic acid can explode at -20 ℃. If the concentration is greater than 45%, it becomes explosive. Therefore, we should avoid contact with high temperatures or reducing agents to avoid dangerous situations.
2. Cyclohexanone peroxide
Cyclohexanone peroxide is one of the Organic peroxides. It is a white crystal and can be dissolved in water, ethanol and ethylene glycol when it is wet. However, this peroxide cannot be exposed to direct sunlight, impact, reducing agents, combustibles, etc., because these will cause fire, explosion, and other dangers. If fire or explosion occurs accidentally, We must use effective extinguishing agents for timely remediation.
3. Dibenzoyl peroxide
Dibenzoyl peroxide is made by slowly dropping dilute hydrogen peroxide into chlorobenzoyl chloride at 0~5 ℃. It is one of Organic peroxides, with strong oxidizing and flammable characteristics. It is very easy to explode when heated, so we must be careful to use it.
