Aromatics - Overview

Aromatic hydrocarbons, also known as arenes or aromatic hydrocarbons, are aromatic compounds composed solely of carbon and hydrogen. The most typical structure of an aromatic compound is a six-carbon ring, called a benzene ring. Benzene, for example, is an aromatic compound with a benzene ring. If the benzene ring is part of a more complex compound, it is called a phenyl group.

Common types

Dimethyl Benzene

Dimethyl benzene is a common industrial chemical solvent.It has strong solubility, can quickly disintegrate oil, resin and other substances. It is indispensable in coating dilution, electronic cleaning and adhesive production.

Pure Benzene

Pure benzene is a colorless, transparent liquid.It has a distinctive aromatic smell, is an extremely important basic chemical raw material. It is widely used in plastics, rubber, dye and other industrial production.

Ethenylbenzene

Ethenylbenzene is a colorless and clear oily liquid. It smells aromatic. It is hardly dissolved in water. It is dissolved in organic solvents, such as ethanol and methanol. Its vapors will be explosive if mixed with the air. The most important purpose of it is to be a monomer of synthetic rubber and plastic.

Product features

Dimethyl Benzene

The volatilization rate is controllable: The boiling point range is moderate. It boils and turns into gas at 136-140℃. The drying speed and leveling can be adjusted.

Insoluble in water: It is insoluble in water and floats on the surface like oil.

Low temperature and good fluidity: Its freezing point is as low as-34℃, and it does not need to be heated for anti-freezing in winter.

Pure Benzene

The boiling point is moderate and controllable: It boils at relatively low temperatures (80°C).

High energy density: As an organic compound, it can release more heat when burned.

Raw materials are abundant: It can be mass-produced. The supply is sufficient and the cost is relatively low.

Ethenylbenzene

High purity performance: It has a very high purity. It has a purity of more than 99%. It can meet the strict requirements of raw materials in the field of fine chemicals and pharmaceuticals. Its high purity will ensure the product quality and reaction efficiency.

Flammable: It is volatile. It has a boiling point of around 145 °C. It must be sealed and stored in a cool and ventilated environment,with out fire sources and high temperature.

Polymerization risk: There will be a polymerization risk when it is in storage and transportation. Appropriate amounts of a polymerization inhibitor should be used. A strict temperature control should also be maintained. Direct sunlight and contact with strong oxidizers should be avoid to prevent polymerization reactions.

Application

The medical field

Pure benzene is an important raw material for the synthesis of many drugs. It can be used to synthesize antibiotics, vitamins and other drugs.

Rubber industry

It is used to produce butadiene rubber (SBR) with butadiene. It is also used to produce styrene-acrylonitrile copolymer (SAN) with acrylonitrile. SBR is widely used in tires, hoses and other industries. On the other hand, SAN has high strength and good heat resistance. It is used to make stationeries and other products. We provide customized products to meet different rubber formulas.

Paint industry

It can be used as a solvent and modifier in paints. By dissolving resins, it can provide good flowability and adhesion. In water-based paints, It can enhance the stability of the paint. We offers high-purity and low-impurity products according to the paint industry, to ensure the quality of paints.

Organic Synthesis Field

It is an important organic synthesis material. It is used to synthesize different compounds and widely used in the fields of pharmaceuticals, pesticides, and fragrances. Our factory has an advanced production processes and strict quality control system. We provide high-purity and high-quality products for the organic synthesis field, and ensure the smooth progress of synthesis reactions and the purity of the products.

FAQ

Q: Is pure benzene corrosive and what materials will it corrode?

A: It has no obvious corrosion at room temperature, and is stable to most materials such as metal and plastic.But prolonged exposure may swell some rubber.

Q: In what specific reactions does the moderate chemical activity of it manifest itself?

A: It is reflected in the reaction of substitution and addition, and the reaction conditions are easy to control, so that the target product can be obtained accurately.

Q: What are the characteristics of its refractive index?In what areas is this feature used?

A: The refractive index is about 1.501, which is relatively stable.It can be used in the laboratory as a refractive index reference solution or to assist in purity detection.

Q: How to store the ethenylbenzene?

A: It must be stored in a cool and dry warehouse. The temperature in the warehouse should be kept below 25°C. A sealed manner is helpful, so that it can avoid contact with moisture in the air. It should be avoided from direct sunshine and contact with oxidizing agents and alkalis. High temperature during a long time storage may cause the color becomes darker, and affect the product quality.

Q: How to judge the quality standards of it?

A: The quality standard for it includes some key indicators. Purity, color, water content,, total aldehyde content, sulfur content, total chlorine content, polymer content, peroxide content, and inhibitor content.

Q: What are the precautions for the toxicity of it?

A: It is low-toxicity. But it still makes certain hazards to human body. It may hurt eyes, skin, and respiratory. To handle it, it needs to be ensured that the workplace has good ventilation. Operators must wear protective gloves, masks and other equipment. Whenever contact the Styrene, some immediate first aid measures should be taken.
