Xylenes are petrochemicals produced by catalytic reforming and coal carbonization in the manufacture of coke fuel. They are used in various industries and medical technology as a solvent. It occurs naturally in coal, wood tar and coal among others. Xylenes are mainly produced as a part of the BTX aromatics. They are derived from various sources within a refinery including pyrolysis gasoline, toluene disproportionation and reformate among others. Reformate accounts for over three fourths of mixed xylenes market. There are three types of xylenes, viz., ortho-xylene, meta xylene and para xylene.
Ortho-xylene is a commercial isomer of xylene. It is a hydrocarbon based on benzene with two methyl substituents bonded to the aromatic ring. It is liquid at room temperature. It is used extensively for producing phthalic anhydride (PAN)-primarily dio-octyl phthalate for PVC. The major use for PAN is for producing plasticizers which are largely used in automobile and construction industry. In addition, it is used in solvent based paints. It is extracted by means of distillation from xylene stream in a plant designed for para-xylene production. It is a constitutional isomer of m-xylene and p-xylene. Moreover, it is produced with its isomers paraxylene, metaxylene and ethylbenzene. Friedel Craft’s alkylation of toluene yields a mixture of ortho-xylene .This reaction gives a pure form of o-xylene. Furthermore, it is used in alkyd resins having wide applications in the coating industry. It has a large demand in the petrochemical industry.
