What about styrene? Styrene is something

It is an important raw material for the manufacture of plastics.

Styrene is an organic compound formed by substituting one hydrogen atom of ethylene.

Styrene is an important basic raw material in the petrochemical industry, and an important monomer in synthetic resins, ion exchange resins, synthetic rubber, etc. Styrene is a colorless oily liquid with an aromatic odor, freezing point, boiling point 145, relative density. When heated or exposed to sunlight, or in the presence of peroxide, it is easy to polymerize, and when polymerized, heat is released and can cause **.

Uses of styrene

Due to its very important properties, styrene can be used as a raw material to produce many useful products, and is widely used in various industries. Styrene is polymerized to produce polystyrene, which is a transparent plastic with good electrical insulation, and is easy to process and mold, and the product is durable, beautiful and cheap.

Styrene butadiene rubber can be prepared by copolymerization of styrene and butadiene, which is a general-purpose rubber with good performance and can be used to manufacture automobile and aircraft tires and various rubber products.

1. As a monomer of synthetic rubber and plastic, it is used to produce styrene-butadiene rubber, polystyrene and foamed polystyrene.

2. Copolymerization with other monomers to manufacture a variety of engineering plastics for different purposes.

3. Mainly used in the manufacture of audio and video products, optical disc disk boxes, lamps and interior decoration parts, and high-frequency electrical insulation parts;

4. Train vehicle parts, auto parts, marine plastic parts, telecommunications electrical parts and building materials;

5. It can be used to process and make films, wire and cable sheaths, pipes, various hollow products, injection molding products, fibers, etc., which are widely used in agriculture, packaging, automobile and other industries.

Styrene is an organic compound formed by replacing a hydrogen atom of ethylene with benzene, the molecular formula is C8H8, the electrons of vinyl are conjugated with benzene ring, insoluble in water, soluble in ethanol and ether, and gradually polymerized and oxidized when exposed to air. Industrially, it is an important monomer for synthetic resins, ion exchange resins and synthetic rubber.

Vinyl smiley finch face does not contain styrene.

Chemical properties: 1. It is easy to be oxidized by oxidants at normal temperature. If ethylene is introduced into an acidic KMNO4 solution, the purple color of the solution fades and ethylene is oxidized to carbon dioxide, which can be used to identify ethylene.

2. It is easy to burn, and emits heat, and the flame is bright when burning, and produces black smoke.

Industrial field: 1. One of the most basic raw materials of petrochemical industry. In terms of synthetic materials, it is widely used in the production of polyethylene, vinyl chloride and polyvinyl chloride, ethylbenzene, benzene, polystyrene and ethylene propylene rubber, etc.; In terms of organic synthesis, it is widely used in the synthesis of ethanol, ethylene oxide and ethylene glycol, acetaldehyde, acetic acid, propionaldehyde, propionic acid and its derivatives and other basic organic synthesis raw materials.

After halogenation, it can be used to produce chlorinated ethylene, chloroethane and bromoethane; Through oligomerization, olefins can be produced, and then higher alcohols, alkylbenzenes, etc.

2. It is mainly used as the standard gas for analytical instruments in petrochemical enterprises.

3. Ethylene is used as an environmentally friendly ripening gas for navel oranges, tangerines, bananas and other fruits.

4. Ethylene is used in pharmaceutical synthesis and high-tech material synthesis. <>
