Organic Peroxides Wear Protective Equipment When Used



Organic peroxides can be decomposed into free radicals and are therefore used primarily as initiators in the polymerization of various monomers. We use organic compounds with different properties depending on the production conditions of the polymerization reaction.

Organic peroxide molecular composition contains peroxy (-O-O-), flammable and explosive, easy to decompose, heat, vibration, friction is extremely sensitive.

Organic Peroxides Hazardous chemicals business in the common organic peroxide varieties are: peracetic acid, methyl ethyl ketone peroxide (catalyst M, resin contact agent), benzoyl peroxide and so on.

The hazardous properties of organic peroxides are as follows.

1. Oxidizing

Organic peroxide because it contains a peroxide (-O-O-), showing a strong oxidation performance, the vast majority can do oxidants. Since organic peroxides also contain hydrogen-containing bonds and other structures with reducing properties, they possess all the conditions of the redox reaction, Organic Peroxides so organic peroxides have a greater risk than other oxidants. Such as: benzoyl peroxide, peracetic acid, Organic Peroxides methyl ethyl ketone peroxide, are prone to explosive self-oxidation decomposition reaction.

2. Decomposition of explosive

The decomposition products of organic peroxides are lively free radicals, and the reaction by free radicals is difficult to suppress by conventional inhibition methods. Because many of its decomposition products are gas or volatile substances, coupled with the provision of oxygen, prone to explosive decomposition. Organic Peroxides The more peroxide content in organic peroxides, the lower the decomposition temperature, the greater the risk. Such as the production of pure diacetyl peroxide stored after 24 hours may be a strong explosion; dibenzoyl peroxide when the water content of 1% (mass fraction) below, a slight friction that can explode; Propyl ester at 10 ℃ above the instability, to 17.22 ℃ when the decomposition of the explosion; peracetic acid (peracetic acid) pure very unstable, at minus 20 ℃ when the explosion, 40% of the solution in the storage process can still Decomposition of oxygen, heated to 110 ℃ when the explosion. It is easy to see that organic peroxides are very sensitive to temperature and external forces, and are more dangerous and hazardous than other oxidants.

3. Flammability

Organic peroxides are flammable, and burn quickly, Organic Peroxides can be quickly converted into explosive reactions. Such as: the flash point of peroxyacetic acid is 40.56 ℃, the flash point of formic acid is 40 ℃, the flash point of t-butoxide is 26.67 ℃, the flash point of di-t-butoxide is 18.33 ℃, The flash point of butyl ester is only 12 ° C.

4. Sensitive to collision or friction

The peroxide (O-O-) in organic peroxides is a very unstable structure that is extremely sensitive to heat, vibration, shock, shock or friction, and is likely to explode when subjected to slight external forces The

For safety and anti-decomposition considerations, organic peroxides should always be stored at the appropriate temperature to store them in the original container to reduce the chance of contamination, Organic Peroxides especially the possibility of being contaminated with strong acids, which is very important The Care should be taken when using ketone peroxides because ketone peroxides react quickly when the transition metal salt concentration is very small. Organic peroxide in the transport should be as far as possible shock, anti-friction, anti-upside down, Organic Peroxides should wear protective equipment in use, to avoid sticking to the skin or into the eyes. The disposal of organic peroxides can be used for incineration, hydrolysis, deep burial and other methods.
