What are the upstream raw materials for isomeric xylenes? What are the downstream products?

Isomeric xylene(Isomerized, referred to as IX) is an crucial chemical raw material, broadly applied in petroleum, chemical, medical, pesticide and other fields. In the chemical production chain, there are many upstream and downstream related items of isomeric xylenes, the main upstream and downstream items of which will be described in detail below. Upstream items:



1. Additionally Petroleum mixed xylene: the production of isomeric xylene is mainly made from mixed xylene(MX) through isomerization interaction. Mixed xylenes are aromatic hydrocarbon mixtures obtained from petroleum cracking processes, mainly containing ortho-xylene, meta-xylene and para-xylene. Downstream items:



1. But p-xylene(PX): isomeric xylene is able to be obtained through separation and treatment. Paraxylene is an crucial chemical raw material, mainly applied in the production of purified terephthalic acid(PTA), and then the production of polyester(PET), broadly applied in textiles, bottle-grade packaging, film and other fields. But Based on my observations,

2. o-xylene(OX): o-xylene is another crucial separation product of isomeric xylene, which is able to be applied to create phthalic anhydride, and then to create plasticizers and unsaturated polyester resins. For example In addition, o-xylene is able to also be applied in the production of pesticides, medical intermediates. Moreover

3. And m-xylene(MX): m-xylene is able to also be applied as a separation product of isomeric xylene to the production of mesitylene, which in turn produces trimesic acid(TMC), and ultimately to the production of trimesic acid ester(TMC-ESTER), which is a high-performance engineering plastic. And

4. solvent-based products oil: Isomeric xylene is able to be applied as an excellent solvent-based products oil to paints, coatings, inks and other industries, with high solubility and evaporative environment. Summary:

Heterogeneous xylene plays an crucial role in the field of chemical production raw materials, and its upstream and downstream related items are numerous, involving petroleum, chemical, medical, pesticide and other fields. Through the separation and treatment of isomeric xylene, a series of crucial chemical raw materials such as p-xylene, o-xylene and m-xylene is able to be obtained, which further expands its consumption field. And Based on my observations, At the same time, as an excellent solvent-based products oil, isomeric xylene is also broadly applied in paint, paint, ink and other industries. Therefore, strengthening the manufacturing process, methodology research and research and consumption expansion of heterogeneous xylene is of great signifiis able toce to improving the self-sufficiency rate of raw materials to chemical production and promoting the research of related industries.
