Introduction
Styrene, is a colorless liquid with a special aromatic odor. The following is an introduction to the properties, uses, preparation methods and safety information of styrene:
Quality:
1. Lighter density.
2. It is volatile at room temperature and has a low flash point and explosion limit.
3. It is miscible with a variety of organic solvents and is an extremely important organic substance.
Use:
1. Styrene is an important chemical raw material, often used in the synthesis of a large number of plastics, synthetic rubber and fibers.
2. Styrene can be used to make synthetic materials such as polystyrene (PS), polystyrene rubber (SBR) and acrylonitrile-styrene copolymer.
3. It can also be used to manufacture chemical products such as flavors and lubricating oils.
Method:
1. Styrene can be obtained by dehydrogenation by heating and pressurizing ethylene molecules.
2. Styrene and hydrogen can also be obtained by heating and cracking ethylbenzene.
Safety Information:
1. Styrene is flammable and should be protected from ignition and high temperatures.
2. Contact with the skin may cause irritation and allergic reactions, and appropriate precautions should be taken.
3. Long-term or substantial exposure may have adverse health effects, including damage to the central nervous system, liver, and kidneys.
4. Pay attention to the ventilation environment when using, and avoid inhalation or intake.
5. Waste disposal should comply with relevant laws and regulations, and should not be dumped or discharged at will.
