Uses and synthesis of 4,4'-Oxydianiline powder

4,4'-Oxydianiline powder can also be used in the production of cross-linking agents, 4,4'-Oxydianiline CAS 101-80-4 is widely used in the production of azo dyes and reactive dyes instead of carcinogenic benzidine. Therefore, 4,4'-Oxydianiline Raw Materials are intermediates with high added value.

Applications / Functions of 4,4'-Oxydianiline powder

• 4,4'-Oxydianiline powder is used as a monomer for polyimide, a high-temperature-resistant polymerisation material, and also in the plastics industry.
• 4,4'-Oxydianiline CAS 101-80-4 Used as intermediate of dyestuff, also used in resin synthesis.
• Fragrance. Dye intermediate. Resin synthesis.

Physicochemical Property of 4,4'-Oxydianiline powder

White or light yellow crystal. Odourless.

Production methodprocess of 4,4'-Oxydianiline powder

React nitrobenzene, nitrochlorobenzene, p-nitrophenol, sodium carbonate and potassium chloride with stirring. After the condensation reaction is completed, cooling, the condensate will be first vacuum distillation, and then changed to water vapour distillation, evaporation until no nitrobenzene in the distillate. The residue was filtered by suction and the filtrate was washed with water until it was colourless, then 4,4'-Oxydianiline Raw Materials was produced.
