CAS NO.: 101-80-4
4,4’-Oxydiniline is another name for 4,4’-diaminodiphenyl ether.
Physical Property
Appearance: Colourless powder or granule (yellow or light grey is allowed). It can dissolve in part of organic solvent, slightly dissolve in ethyl alcohol and diluted hydrochloric acid, insoluble in water.
Application Area
① It is one of the important raw material in synthesizing monomers of polyimide resin.
② It is also used for raw material and cross-linking agent of high-performance epoxy resin.
③ Meanwhile, it is used to replace carcinogen benzidine in producing azo dyes, reactive dyes and perfume etc.
Package: Inner packing is vacuum package with aluminum film bag; outer packing is carton or fiber can, or order by customer.
Storage: Guarantee period is for one year under the conditions of protection from light, shade, ventilation, dry and seal oxygen insulation.
According to different production process, our products are divided into sublimation and re-crystallization product.
