Ethyl propyl acrylate nitrile (EAN) is an important chemical raw material, which is widely used in synthetic rubber, plastic, fiber and other fields. In the upstream and downstream related products of EAN, the following aspects are mainly involved:

1. Upstream raw material

The upstream raw materials of EAN mainly include propylene, acrylic acid, acrylonitrile, etc. Among them, propylene is an important petrochemical raw material, mainly obtained by petroleum cracking; acrylic acid can be obtained by propylene oxidation method; acrylonitrile is obtained by propylene ammoxidation method. The market supply of these raw materials, price fluctuations, etc. will have an impact on the production of EAN.

2. Downstream products

EAN's downstream products mainly include synthetic rubber, plastics, fibers, etc. Among them, synthetic rubber can be used to produce tires, hoses, tapes and other products; plastics can be used to produce various daily necessities, electrical parts, building materials, etc.; fibers can be used to produce textiles, non-woven fabrics and other products. The demand situation and development trend of these downstream products will have an impact on the market demand of EAN.

Specifically, the downstream associated products of EAN include:

(1) butyl acrylate: EAN can be esterified with butanol to produce butyl acrylate, which is an important acrylate monomer and can be used to produce acrylic resins, coatings, adhesives and other products.

(2) Acrylamide: EAN can hydrolyze with water to produce acrylamide, which is an important organic chemical raw material and can be used to produce polyacrylamide, water treatment agents and other products.

(3) acrylonitrile-butadiene-styrene copolymer (ABS):EAN can be copolymerized with butadiene, styrene and other monomers to produce ABS resin, which is a commonly used engineering plastic with excellent impact resistance, heat resistance, chemical resistance and other properties.

In summary, the upstream and downstream related products of ethyl propyl acrylate nitrile are very extensive, involving many fields, such as petrochemicals, synthetic rubber, plastics, fibers, etc. The market situation and development trend of these related products will have an impact on the production and sales of EAN.
