Xylene: Properties, Production, Grades and Industrial Applications

Xylene, also known as dimethylbenzene, is a volatile aromatic hydrocarbon compound derived from petroleum refining and coal tar processing. As one of the most fundamental and widely used bulk organic solvents and chemical intermediates, xylene features low viscosity, strong dissolving capacity, stable chemical performance and excellent compatibility with various organic materials. It plays an irreplaceable role in paint coating, printing ink, synthetic resin, chemical synthesis and petrochemical industries, serving as a core raw material in modern fine chemical manufacturing.

Basic Physical and Chemical Properties

Isomer Classification and Product Grades

Ortho-Xylene (OX) is mainly used for the synthesis of phthalic anhydride, which is widely applied in plasticizers, coatings and resin materials production. It provides excellent toughness and adhesion properties for downstream polymer products.

Production Process and Manufacturing Technology

Core Industrial Applications

In the petrochemical and synthetic material industry, high-purity PX is the fundamental raw material for polyester industrial chains. It is oxidized and polymerized to produce polyester chips, polyester fibers, plastic films and plastic containers, which are widely used in textile clothing, packaging materials and engineering plastics fields. OX and MX provide key intermediates for plasticizer, resin and special polymer synthesis.
