Isomeric xylene (Isomerized, IX) is an important raw material for chemical production, which is widely used in petroleum, chemical, pharmaceutical, pesticide and other fields. In the chemical production chain, there are many upstream and downstream related products of isomeric xylenes, the main upstream and downstream products of which will be described in detail below.
upstream products:
1. petroleum mixed xylene: the production of isomeric xylene mainly takes mixed xylene (MX) as raw material and is produced by isomerization reaction. Mixed xylenes are aromatic hydrocarbon mixtures obtained from petroleum cracking processes, mainly containing ortho-xylene, meta-xylene and para-xylene. Downstream products of
:
1. p-xylene (PX): isomeric xylene can be obtained through separation and purification. Paraxylene is an important chemical raw material, mainly used in the production of purified terephthalic acid (PTA), and then the production of polyester (PET), widely used in textiles, bottle-grade packaging, film and other fields.
2. o-xylene (OX): o-xylene is another important separation product of isomeric xylene, which can be used to produce phthalic anhydride, and then to produce plasticizers and unsaturated polyester resins. In addition, o-xylene can also be used in the production of pesticides, pharmaceutical intermediates.
3. m-xylene (MX): m-xylene can also be used as a separation product of isomeric xylene for the production of mesitylene, which in turn produces trimesic acid (TMC), and finally for the production of trimesic acid ester (TMC-ESTER), which is a high-performance engineering plastic.
4. Solvent oil: Isomerized xylene can be used as an excellent solvent oil for paints, coatings, inks and other industries, with high solubility and volatility.
summary:
isomeric xylene plays an important role in the field of chemical production raw materials, and its upstream and downstream related products are numerous, involving petroleum, chemical, pharmaceutical, pesticide and other fields. Through the separation and purification of isomeric xylene, a series of important chemical raw materials such as p-xylene, o-xylene and m-xylene can be obtained, which further expands its application field. At the same time, as an excellent solvent oil, isomeric xylene is also widely used in paint, paint, ink and other industries. Therefore, strengthening the production process, technology research and development and application expansion of heterogeneous xylene is of great significance for improving the self-sufficiency rate of raw materials for chemical production and promoting the development of related industries.
