Tert-butyl peroxybenzoate (Tert-Butyl Peroxybenzoate, TBPB) is an important organic peroxide, which is widely used as a raw material for chemical production. In this paper, the properties and uses of tert-butyl peroxybenzoate are discussed in detail.

1. The properties of tert-butyl peroxybenzoate

1. Physical properties
tert-butyl peroxybenzoate is a colorless to slightly yellow transparent liquid with a faint special smell. Its molecular formula is C11H14O4 and its molecular weight is 210.23. Tert-butyl peroxybenzoate is insoluble in water, but soluble in most organic solvents, such as ethanol, ether, acetone, benzene, etc.

2.
of chemical properties tert-butyl peroxide benzoate has strong oxidation, and it is easy to decompose under heat, friction, vibration or acid, alkali and other conditions to produce free radicals, thus triggering polymerization reaction. Therefore, special care is required during storage and transportation.

2. The use of tert-butyl peroxybenzoate

1. polymerization initiator
tert-butyl peroxybenzoate can be used as a polymerization initiator, widely used in unsaturated polyester, acrylic acid, vinyl chloride and other monomers in the polymerization reaction. Under high temperature conditions, tert-butyl peroxybenzoate decomposes to generate free radicals, which initiate the polymerization of monomers and generate high molecular compounds.

2. crosslinking agent
tert-butyl peroxide benzoate can be used as crosslinking agent for rubber, plastics and other polymer materials crosslinking modification. Through the crosslinking reaction, the heat resistance, oil resistance, creep resistance and other properties of the material can be improved.

3. bleaching agent
tert-butyl peroxide benzoate has a certain bleaching effect, can be used for paper, textiles and other bleaching treatment. It removes the pigment through oxidation and makes the color of the item white.

4. flame retardant
tert-butyl peroxide benzoate can be used as flame retardant, added in plastics, rubber and other polymer materials, improve the flame retardant properties of materials. Under high temperature conditions, the free radicals produced by the decomposition of tert-butyl peroxybenzoate can react with polymer materials to form a non-combustible carbonized layer, thereby preventing the spread of flame.

In conclusion, tert-butyl peroxybenzoate has a wide range of applications in the field of chemical production raw materials, such as polymerization initiators, crosslinking agents, bleaching agents and flame retardants. However, due to its strong oxidation and potential explosion, it is necessary to strictly abide by the safety operation procedures during use to ensure production safety.
