Styrene is an important organic chemical raw material, which is widely used in the production of plastics, resins, synthetic rubber and other fields. This article will detail the properties and uses of styrene.

1. the nature of styrene

styrene is a colorless transparent, aromatic smell of liquid. It is insoluble in water but miscible with many organic solvents. The chemical properties of styrene are more lively, prone to polymerization, oxidation, addition and other reactions.

1. polymerization

styrene monomer can be self polymerization reaction, the formation of polystyrene. Polystyrene is a colorless and transparent hard plastic with good insulation, corrosion resistance and processing performance. It is widely used in the manufacture of electrical parts, daily necessities, toys, etc.

2. Oxidation

Styrene can be oxidized to form benzaldehyde or benzoic acid. These compounds are also important organic chemical raw materials for the production of spices, pharmaceuticals, pesticides and other products.

3. addition reaction

styrene can react with hydrogen, halogen, acid, etc. to generate corresponding compounds. These compounds can be used as intermediates in organic synthesis and further converted into other useful compounds.

2. the use of styrene

styrene as an important organic chemical raw material, in the field of chemical production raw materials has a wide range of uses. The following are the main uses of styrene:

1. Production of polystyrene

Styrene monomer can produce polystyrene through polymerization, which is a widely used plastic material. Polystyrene has excellent insulation, corrosion resistance and processing performance, so it is widely used in the manufacture of electrical parts, daily necessities, toys and other products.

2. Production of synthetic rubber

styrene can be copolymerized with other monomers to produce synthetic rubber, such as styrene butadiene rubber, chloroprene rubber, etc. These synthetic rubbers have excellent wear resistance, aging resistance and tear resistance, so they are widely used in the manufacture of tires, rubber hoses, tapes and other products.

3. the production of ion exchange resin

styrene can be copolymerized with divinylbenzene and other monomers to generate ion exchange resin. This resin has good ion exchange performance and is widely used in water treatment, chemical separation and other fields.

4. Production of spices and pharmaceutical intermediates

styrene can generate benzaldehyde and benzoic acid through oxidation reaction, these compounds are important raw materials for the production of spices and pharmaceutical intermediates.

In short, styrene, as an important organic chemical raw material, has a wide range of uses in the field of chemical production raw materials.
