Read： 951 Time：13months ago Source：Transform the World with Simplicity

Chlorobenzene is an important raw material for chemical production, which has a wide range of properties and uses. This article will detail the nature of chlorinated benzene, production methods, uses and safety knowledge.

1. the nature of chlorinated benzene

chlorinated benzene is a colorless, transparent, pungent odor liquid, insoluble in water, soluble in organic solvents. It is highly corrosive and can react with many metals to form salts. The chemical properties of chlorinated benzene are relatively stable, but it is prone to decomposition and reaction under high temperature, light and acidic conditions.

2. chlorinated benzene production method

chlorinated benzene production method mainly has two kinds: one is benzene and chlorine direct chlorination method, the other is benzene and hydrogen chloride indirect chlorination method. Among them, the direct chlorination method is a commonly used production method at home and abroad, which has the advantages of simple process, convenient operation and low production cost.

3. the use of chlorinated benzene

Chlorinated benzene is an important organic chemical raw materials, widely used in medicine, pesticides, dyes, spices, plastics, synthetic fibers and other fields. Specifically, the use of chlorinated benzene includes the following aspects:

1. pharmaceutical field: chlorinated benzene can be used as an intermediate in the synthesis of drugs, used in the production of antibacterial drugs, antipyretic analgesics, anticancer drugs and other drugs.

2. Pesticide field: Chlorobenzene can be used as an intermediate in the synthesis of pesticides for the production of pesticides, fungicides, herbicides and other pesticides.

3. Dye field: Chlorinated benzene can be used as an intermediate in the synthesis of dyes for the production of dyes of various colors.

4. perfume field: chlorinated benzene can be used as an intermediate in the synthesis of spices and is used to produce various fragrances.

5. Plastics and synthetic fibers: Chlorinated benzene can be used as a monomer or comonomer of plastics and synthetic fibers for the production of various plastics and synthetic fibers.

4. the safety
of chlorinated benzene
chlorinated benzene has certain toxicity and corrosiveness, and has irritating effect on eyes, skin and respiratory system. Therefore, in the process of production and use, it is necessary to strictly abide by the safety operation procedures, wear protective equipment, and avoid contact with skin and eyes. At the same time, the waste gas and waste water of chlorinated benzene also need to be strictly treated to reduce the harm to the environment and human body.

In conclusion, chlorinated benzene, as an important raw material for chemical production, has a wide range of properties and uses. In the process of production and use, it is necessary to strictly abide by the safety operation procedures and take protective measures to ensure the safety of production and use.
