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 and regulators. Therefore, peroxides can now be used in many fields and are very popular. What are common organic peroxides and what are their characteristics.
1. Peracetic acid
Peracetic acid is made by reacting acetic acid with hydrogen oxide in the presence of sulfuric acid. It is a colorless liquid with strong smell. It is very unstable, as long as the temperature is slightly higher, it will decompose hydrogen and explode. Generally, pure acetic acid will explode at - 20 ℃. If the concentration is greater than 45%, it will be explosive. Therefore, we should avoid contact with high temperature or reducing agent to avoid dangerous situations.
3. 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 agent, inflammables, etc., because these will cause it to fire, explosion and other dangers. If it is accidentally exposed to fire or explosion, We must use effective fire extinguishing agents for timely remedy.
4. Dibenzoyl peroxide
Dibenzoyl peroxide is made by slowly dropping dilute hydrogen peroxide into chlorobenzoyl chloride at 0~5 ℃. It is one of the organic peroxides with strong oxidizing and flammable characteristics. It is very easy to explode when heated, so we must be careful when using it.
