Applicazione

1. Oxidation reaction: TBHP is a strong oxidizing agent that can oxidize a variety of organic compounds, including olefin, mercaptan, fatty alcohol, eccetera. It is often used in oxidation reactions in organic synthesis, such as oxidizing alkanes to produce aldehydes and ketones.

2. Free radical reaction: chemical tert-butyl hydrogen peroxide can decompose under appropriate conditions to produce free radicals, thereby participating in free radical reactions. Per esempio, it can participate in mercaptan radical polymerization reactions for the synthesis of polymers and resins.

3. Catalizzatore: tert-butyl hydrogen peroxide can be used as a catalyst to participate in some chemical reactions, such as oxidation reaction, double bond ring-opening reaction.

4. Synthetic intermediates: China tert-butyl hydrogen peroxide is also used as an intermediate for the synthesis of other compounds. Per esempio, it can react with tert-butyl methyl ether to produce p-tert-butyl benzenol peroxide as an intermediate for some organic synthesis reactions.

Hazard Characteristics

Hazardous characteristics flammable and strong oxidizing. When exposed to high heat, sun exposure, impact or contact with reducing agents and flammable substances such as sulfur and phosphorus, there is a danger of combustion and explosion.
Combustion (decomposition) products carbon monoxide, diossido di carbonio.
Fire fighting method firefighters must operate in an explosion-proof shelter.
Extinguishing agent water, foam, diossido di carbonio, sand. Do not approach easily in case of fire. If there is a fire near the material, keep the container cool with water.
