Product Description

   Factory Supply 4,4'-Oxydianiline (ODA) CAS 101-80-4 in Srock

Product Description

Bis(p-aminophenyl) Ether is a reagent used in the preparation of polyimide-silica composite membranes for gas separation techniques. In addition, it is used in the synthesis of polymer films for electrolyte membranes.As a kind of special engineering material, polyimide has the advantages of high temperature resistance, radiation resistance and high mechanical strength, and is used in film, coating, fiber, aerospace, electronic and electrical industry, foam and photoresist. 4,4' -diaminodiphenyl ether is one of the main Chemicalbook raw materials. At the same time, 4,4' -diaminodiphenyl ether can also be used in the production of crosslinking agents, and is widely used in the production of azo dyes and reactive dyes instead of benzidine, which has carcinogenic effects. Therefore,4,4' -diaminodiphenyl ether is an intermediate with high added value.

Application

It is one of the important raw materials of new special engineering plastic polyimide, polyetherimide, polyester imide, polymaleimide, polyarylamide and other high temperature resistant resins; 2. It is also the raw material for the synthesis of 3,3', 4,4' -tetraminodiphenyl ether, which is the main monomer for the preparation of a series of aromatic heterocyclic heat resistant polymer materials. 3. It is also used as a high-performance heat-resistant epoxy resin, polyurethane and other synthetic polymers of the original Chemicalbook material and crosslinking agent. 4. At the same time, it is also used to replace benzidine with carcinogenic effect in the production of azo dyes, reactive dyes and spices. At present, diaminodiphenyl ether has been used as raw material to develop direct dyes of different color levels, such as bright red, brilliant red, sand red, yellow brown, green, gray, blue, brilliant orange, black, etc., which can be used for dyeing silk, wool, cotton, linen and other fabrics, and its color fastness and dyeing rate are superior to benzidine dyes.
