1 2 dibromobenzene properties applications production
Regarding 1,2-dibromobenzene
1,2-dibromobenzene, it has unique properties. Its color is colorless to light yellow, it is a flowing liquid, has a special odor, and has a certain volatility. The melting point is about -7 ° C, the boiling point is about 224 ° C. The density is higher than that of water, and it is insoluble in water, but it can be miscible with most organic solvents.
This substance is widely used. In the field of organic synthesis, it is often used as a key intermediate. It can be reacted in a series to produce a variety of bromine-containing organic compounds, such as intermediates for medicines, pesticides, and dyes. In materials science, it also plays an important role in the preparation of special polymer materials and can be used to improve the flame retardancy and stability of materials.
The production method mostly uses benzene as the starting material. Under the action of a catalyst, benzene and bromine undergo a substitution reaction. Commonly used catalysts include iron filings, iron tribromide, etc. During the reaction, the reaction temperature, bromine dosage and other conditions are controlled to improve the yield and purity of 1,2-dibromobenzene. After the reaction, high-purity 1,2-dibromobenzene products are obtained through separation and purification steps such as distillation and extraction. During the production process, attention should be paid to safety protection, because it has certain toxicity and irritation, and may be harmful to human body and the environment.
