Isophthalonitrile plays an important role in the field of raw materials for chemical production, and its upstream and downstream related products are extensive. The upstream and downstream associated products of isophthalonitrile will be described in detail below.

upstream products:

1. Aniline: Aniline is one of the main raw materials of isophthalonitrile, which can be converted into isophthalonitrile through chemical reaction. The production methods of aniline mainly include nitration, reduction and catalytic hydrogenation.
2. sodium cyanide: sodium cyanide is also an important raw material for the production of isophthalonitrile, and aniline reaction to generate isophthalonitrile. The production methods of sodium cyanide include electrolysis method, acrylonitrile by-product method, etc.

downstream products:

1. isophthalic acid: isophthalonitrile can be hydrolyzed to generate isophthalic acid, which is an important organic chemical raw material, widely used in the production of dyes, pharmaceuticals, pesticides and other intermediates.
2. m-phenylenediamine: m-phenylenediamine can be reduced to generate m-phenylenediamine, which is also an important organic chemical raw material for the production of rubber antioxidants, antioxidants, dyes, etc.
3. Polymer: isophthalonitrile can be used as a monomer and copolymerized with other monomers to produce polymers, such as polyamide, polyester, etc. These polymer materials have excellent properties and are widely used in engineering plastics, fibers and other fields.

From the above introduction, it can be seen that the upstream and downstream related products of isophthalonitrile are very extensive, involving dyes, medicines, pesticides, rubber, engineering plastics and other fields. The production and use of these products is of great significance to promote the development of the chemical industry, and also provides a broad development space for the production and application of isophthalonitrile. In the production process of

, we need to pay attention to safety, environmental protection and other issues to ensure product quality and sustainability. In the future, with the continuous progress of technology and the expansion of application fields, the production and application of isophthalonitrile and its related products will continue to grow.
