Organic Intermediate 4,4'-Oxydianiline Cas 101-80-4 Dye Intermediates

Introduction:

4,4'-Oxydianiline can be used to produce crosslinking agents and is widely used to replace carcinogenic benzidine in the production of azo dyes and reactive dyes. Therefore, 4,4'-Oxydianiline is an intermediate with high added value.

Uses:

1. It is one of the important raw materials for new special engineering plastics such as polyimide, polyetherimide, polyesterimide, polymaleimide, polyaramid and other high temperature resistant resins;
2. It is also the raw material for synthesizing 3,3', 4,4'-Oxydianiline, which is the main monomer for preparing a series of aromatic heterocyclic heat-resistant polymer materials.
3. It is also used as a chemicalbook raw material and crosslinking agent for synthetic polymers such as high-performance heat-resistant epoxy resins and polyurethanes.
4. It is also used to replace carcinogenic benzidine in the production of azo dyes, reactive dyes and spices. At present, direct dyes of different color levels such as bright red, bright red, sand red, yellow brown, green, gray, blue, bright orange and black have been developed using diaminodiphenyl as raw material. They can be used for dyeing silk, wool, cotton, linen and other fabrics. Their color fastness and exhaustion rate are better than benzidine dyes.
