The upstream and downstream associated products
of methacrylonitrile
methacrylonitrile is an important organic chemical raw material, which is widely used in the production of a variety of chemicals. Understanding its upstream and downstream related products is helpful to understand the application of methacrylonitrile in the field of chemical production. This paper will discuss the upstream and downstream associated products of methacrylonitrile, including upstream raw materials and downstream products.

1. Upstream Raw Material

1. Propylene: Propylene is one of the main raw materials of methacrylonitrile, which can be produced by propylene ammoxidation.
2. Ammonia: Ammonia is another important raw material in the production of methacrylonitrile, which reacts with propylene to produce methacrylonitrile.
3. Air: Oxygen in the air is used as an oxidant to participate in the ammoxidation of propylene to generate methacrylonitrile.

2. Downstream Products

1. Polyacrylonitrile (PAN): Methacrylonitrile can be polymerized to generate polyacrylonitrile, which is a polymer compound widely used in the production of synthetic fibers, carbon fibers, ultrafiltration membranes and other materials.
2. Methyl methacrylate (MMA): Methacrylonitrile can be esterified with methanol to produce methyl methacrylate, which is an important chemical raw material for the production of organic glass, coatings, adhesives and other fields.
3. ethyl acrylate: ethyl acrylate can be obtained by the reaction of methacrylonitrile and ethanol, which is used in the production of coatings, adhesives, plastics, etc.
4. ethyl cyanoacrylate: ethyl cyanoacrylate can be obtained by the reaction of methacrylonitrile and chloroethanol, which is a fast-curing adhesive, widely used in automotive, aviation, electronics and other industries.
5. Methyl salicylate: Methyl salicylate can be obtained by the reaction of methacrylonitrile and salicylic acid, which is a raw material for the production of drugs, spices and other compounds.

summary

methacrylonitrile as an important organic chemical raw material, plays an important role in the production of chemical products. Its upstream and downstream related products cover a variety of fields, including synthetic fibers, polymer materials, coatings, adhesives, drugs, etc. Understanding the upstream and downstream related products of methacrylonitrile will help enterprises to optimize the production process, improve the efficiency of resource utilization, and also help to develop new applications and promote the sustainable development of the chemical industry.
