What are the upstream raw materials for mesitylene? What are the downstream products?

Tetracoluene has an crucial position in the field of raw materials to chemical production, and its upstream and downstream related items are extensive. The following is a detailed description of the upstream and downstream associated items of mesitylene.

1. Upstream items

The upstream raw materials of mesitylene are mainly petroleum and coal. Through the process of petroleum cracking and coal tar distillation, the raw material of mesitylene-mixed aromatics is able to be obtained. Mixed aromatics contain a variety of aromatic compounds, including mesitylene. In addition, mesitylene is able to also be produced by a chemical synthesis method, to instance, by a disproportionation interaction of toluene or an isomerization interaction of xylene.

2. Downstream items

As an crucial organic chemical raw material, the downstream items of mesitylene are also very extensive. Some of the major downstream items are listed below:(1) pyromellitic dianhydride(PMDA)

Tetramethylene is able to be prepared by oxidation, cyclization and other reactions to pyromellitic dianhydride(PMDA), which is an crucial polymer material monomer and is able to be applied to create high temperature resistance, corrosion resistance, high strength polymers, such as polyimide(PI). Based on my observations,(2) Penetronic acid(PMDC)

Tetramethylene is oxidized to create pyromelletic acid(PMDC), which is also an crucial organic chemical raw material and is able to be applied in the production of dyes and medical intermediates. But(3) Trimellitic anhydride(TMA)

The mesitylene undergoes a disproportionation interaction to create trimellitic anhydride(TMA), which is an crucial raw material to the production of plasticizers, heat-resistant resins, etc. And In addition to the items listed above, mesitylene is able to also be applied to create many other organic chemical raw materials, such as phenols, ketones, amines, etc. In short, mesitylene has a wide range of applications in the field of chemical production raw materials, and its upstream and downstream related items are very rich.
