1,2-DICHLOROBENZENE, [14C(U)] - Introduction
1,2-Dichlorobenzene is an organic compound with the chemical formula C6H4Cl2. It is a colorless liquid with a special aromatic smell. The following is an introduction to the nature, use, preparation and safety information of 1,2-dichlorobenzene:
Nature:
1,2-Dichlorobenzene is a colorless liquid at room temperature with a density of 1.31g/cm³. It has a boiling point of 180°C and a melting point of -17°C. It is insoluble in water and highly soluble in organic solvents. 1,2-Dichlorobenzene is sensitive to light, unstable, and can react with permanent silver nitrate.
Use:
The main use of 1,2-dichlorobenzene is as an intermediate in organic synthesis. It can be used to make medicines, dyes, pesticides and other organic compounds. In addition, it is also used in solvents, metal cleaners and the electronics industry.
Preparation Method:
The method for preparing 1,2-dichlorobenzene can be obtained by reacting halogenated benzene with hexachloroaminobenzene (or dichloroaniline). One commonly used method is the reaction of 1,2-dichloroaniline with a metal chloride to form 1,2-dichlorobenzene.
Safety Information:
1,2-Dichlorobenzene is toxic in contact with the skin and when inhaled. It should avoid contact with skin and be careful to use respiratory protective equipment when using it. In addition, it should also be used in a well-ventilated environment. In the handling of 1,2-dichlorobenzene, the relevant safe operating procedures should be observed and the storage and disposal of waste should be properly managed.
