What are Ketone Peroxides?

Professional Ketone Peroxides are a class of organic compounds that contain a peroxide functional group (-O-O-), attached to a ketone group (C=O). They are derived from ketones and are highly reactive due to the presence of the peroxide moiety.
The general formula for a ketone peroxide is R-CO-O-O-R', where R and R' represent alkyl or aryl groups. The peroxide group can be located on different positions of the ketone molecule, resulting in various isomers.
Professional Ketone Peroxides are typically prepared by reacting ketones with hydrogen peroxide (H2O2) in the presence of an acid catalyst. The reaction involves the formation of a peracid intermediate, which then decomposes to yield the ketone peroxide. This process is known as the Baeyer-Villiger oxidation.

One of the most well-known Good Quality Ketone Peroxides is methyl ethyl ketone peroxide (MEKP). It is commonly used as a radical initiator in the polymerization of unsaturated polyester resins, which are widely employed in the production of fiberglass-reinforced plastics. MEKP is a colorless liquid with a pungent odor and is highly reactive.
Good Quality Ketone Peroxides exhibit strong oxidizing properties due to the presence of the peroxide group. They can undergo homolytic cleavage of the O-O bond, generating highly reactive oxygen-centered radicals. These radicals can initiate various chemical reactions, such as polymerization, oxidation, and radical addition reactions.

However,Widely Use Ketone Peroxides are highly sensitive to heat, shock, and friction, making them extremely hazardous. They are prone to decomposition, which can lead to violent and explosive reactions. Therefore, proper handling and storage of ketone peroxides are crucial to ensure safety.
In summary,Widely Use Ketone Peroxides are organic compounds containing a peroxide functional group attached to a ketone group. They are prepared by reacting ketones with hydrogen peroxide and are highly reactive due to the presence of the peroxide moiety. Ketone peroxides find applications as radical initiators in polymerization reactions but require careful handling due to their explosive nature.
