Brief Introduction: 4,4'-Diaminodiphenyl ether(ODA) , 4,4'-Oxydianiline, 4,4'-Oxybisbenzenamine,
Bis (p-aminophenyl) ether
Molecular formula: C12H12N2O     Molecular weight:200.24
We use the reduction process of hydrogen technology, ODA has high purity and top quality.
Physical property:
the product is a grey-white or white crystal powder . the product has excellent physical stability and chemical stability. it can dissolve in the DMAC(N,N-dimethylacetamide),DMF(N.N-dimethyformamide)
organic solvent, but it does not dissolve in the water, it dissolves in the ethyl alcohol slightly, it can dissolve dilute hydrochloric acid.
