Description
1. Chemical properties and classification
4 4′-Oxydianiline， Commonly known as 4 4 ‘- diaminodiphenyl ether, it is an aromatic diamine monomer. Its chemical formula is C ₁₂ H ₁₂ N ₂ O, molecular weight is 200.24, CAS number is 101-80-4, and it is a colorless or white crystalline powder at room temperature.
2. Physical characteristics and morphology
The melting point of this compound is about 188-192 ° C, with a boiling point higher than 300 ° C and a flash point of about 218 ° C. It is easily soluble in hydrochloric acid, but insoluble in water and soluble in organic solvents such as acetone. However, it is sensitive to light and needs to be sealed and stored away from light.
3. Cancer risk warning
This substance is classified as a “reasonably expected human carcinogen” by the US Department of Health and Human Services and as a Group 2B carcinogen by the International Agency for Research on Cancer of the World Health Organization. Animal experiments have shown that oral or injection of this substance can induce tumors in multiple organs such as the liver and thyroid. Wear protective equipment during operation to avoid inhaling dust or skin contact, and strictly prevent it from polluting water sources.

The application of 4 4'-Oxydianiline
The main uses of 4 4′-Oxydianiline
The core value of 4 4′-Oxydianiline lies in its molecular structure containing two highly active amino groups (- NH ₂), which are mainly used as “molecular bridges” for the synthesis of various high-performance polymers.
Core monomer of high-performance polyimide
The main and core use of 4 4′-Oxydianiline is as a monomer for the production of polyimide. Polyimide materials with extremely high heat resistance and excellent mechanical properties can be manufactured by condensation reaction with aromatic dianhydride such as phthalic anhydride. The Kapton film manufactured based on this is widely used in flexible printed circuit boards, motor slot insulation, and thermal insulation materials for spacecraft.
Special coatings and composite material matrices
4 4′-Oxydianiline is also a key raw material for producing polyester imide resin, which is the main component for manufacturing high-temperature resistant enameled wire paint. The enameled wire paint used for motor and transformer windings can ensure that it does not age or break in high temperature environments. In addition, it is also used as a high-temperature structural adhesive for metal to metal bonding, as well as a prepreg matrix resin for radar covers and honeycomb sandwich structures, ensuring the structural strength of aircraft during high-speed flight.
Heat resistant curing agent for epoxy resin
In addition to polyimide, 4 4′-Oxydianiline is also a high-performance curing agent for epoxy resins. The epoxy resin cured by it has extremely high heat deformation temperature and excellent chemical and water resistance, making it suitable for manufacturing high-strength laminates, heat-resistant molds, and matrix of composite materials.
In summary, the use of 4 4′-Oxydianiline is highly concentrated in the field of cutting-edge materials and is a key link connecting modern chemistry and advanced manufacturing. It is not only the cornerstone of high-temperature resistant polyimide materials and special coatings that are indispensable in the manufacturing of electronics and aerospace fields, but also a key additive to enhance the performance of high-end epoxy resin composite materials.
