Ethylenediamine is an organic amine with the chemical formula H2NCH2CH2NH2. It is a colorless, volatile liquid, soluble in water and a variety of organic solvents. Ethylenediamine is a commonly used chemical with a wide range of applications. The following are the main applications of ethylenediamine:

1.

in the field of medicine Ethylenediamine is an important intermediate that can be used for the synthesis of drugs and pharmaceutical intermediates. For example, ethylenediamine and acetone can be synthesized hypertension drug nifedipine; ethylenediamine and 1,2, 4-trichlorobenzene can be prepared anticancer drug etoposide, etc. In addition, ethylenediamine can also be used as an organic synthesis catalyst, which plays an important role in promoting the synthesis of natural products.

2.

in the electronics industry Ethylenediamine can be used as a precursor of optical functional materials for the preparation of optical fibers, optical waveguides and other devices. It can also be used to prepare electronic devices such as capacitors, circuit boards, and semiconductor devices. Ethylenediamine can be combined with lithium hydroxide to prepare high-performance lithium-ion batteries.

3.

in the petrochemical field Ethylenediamine can be used as an extractant and dispersant for the separation and extraction of petrochemical products and organic substances, such as alkylbenzenes and phenols. For example, ethylenediamine can be used as a cross-linking agent for polyacrylamide (PAM) to improve the efficiency of oil collection.

4. Metal processing

Ethylenediamine can be used as a component of metal processing lubricants to smooth the surface of the metal while protecting the metal from corrosion and oxidation. Ethylenediamine can also be used as a complexing agent for cobalt, nickel and other metal casting, which can improve the structure and performance of the metal, and improve the strength and corrosion resistance of the metal.

ethylenediamine is an important chemical with a wide range of applications. It plays an important role in the fields of medicine, electronics, petrochemical and metal processing. In the future, with the continuous development of science and technology and the needs of different fields, the application fields of ethylenediamine will continue to expand and enrich.
