Mixed-Xylene is a mixture of the three xylene isomers that is widely used as solvent. Commercial or mixed xylene usually contains about 40-65% m-xylene and up to 20% each of o-xylene and p-xylene and ethylbenzene. The blend of xylene is the second most widely used aromatic product in the world. Also it has been used to produce chemical products after benzene and before toluene. The mixture of xylene is a combination of four isomers with the chemical structure of C8H10, which are found in compounds in great order, including methicillin, isothiazolene, para-xylene, and ethylbenzene.
Xylenes are produced in a variety of ways. When refined oil refineries enter the refinement process, aromatic products are a major part of the output stream. The separation of this stream is the main source of xylene production, which includes more than 70% of world production. Also, in the static cracking process in olefin units, a mixture of xylene is also produced. Also, the conversion of toluene to benzene and the mixture of xylene, as well as the processing of benzine pyrolyzes, is among other methods of producing xylene.
- Paraxylene, orthoxylene and metaxylene separation – The major use of the world’s xylene mixture is the production of various xylene isomers, para-xylene, isothiazolene and metazilen, which are used in the production of terephthalic acid, phthalic acid, and isophthalic acid, respectively. The ultimate applications of these products are the production of polyethylene terephthalate resins, polystyrene platings, and coating plasticizers.
- Add to gasoline – This product has a high octane number as well as low vapor pressure and an excellent combination to add to gasoline.
- The chemical industry – is used in the chemical industry to produce color and solvent from this product.
