Application of 4 4'-Oxydianiline
1. It is one of the important raw materials for high temperature resistant
resins such as polyimide, polyetherimide, polyesterimide, polymaleimide, and
2. It is also the raw
material for the synthesis of 3,3',4,4'-tetraaminodiphenyl ether, which is the
main monomer for preparing a series of aromatic heterocyclic heat-resistant
3. It is also used as
a raw material and cross-linking agent for high-performance heat-resistant
epoxy resin, polyurethane and other synthetic polymers.
4. At the same time,
it is also used in the production of azo dyes, reactive dyes and perfumes to
replace benzidine which has carcinogenic effects.
