Xylene, with the CAS number 1330-20-7, is a colorless, volatile liquid known for its sweet odor and flammability. It is a mixture of three isomers: ortho-xylene, meta-xylene, and para-xylene, which differ in the arrangement of methyl groups on the benzene ring. This chemical is widely used in various industrial applications due to its excellent solvent properties.
Uses of Xylene
Industrial Applications: Xylene is extensively utilized in the manufacturing of paints, coatings, varnishes, and adhesives. Its ability to dissolve organic compounds makes it invaluable in these industries.
Histology: In the field of histology, xylene serves as a clearing agent, essential for preparing tissue samples for microscopic examination. It is used to remove paraffin from tissue sections prior to staining and coverslipping.
Chemical Synthesis: Xylene is also a precursor in the production of important chemicals such as terephthalic acid and dimethyl terephthalate, which are key raw materials for producing polyethylene terephthalate (PET) plastics.
Environmental Studies: Due to its volatility, xylene is a subject of environmental research, focusing on its impact on air quality and its biodegradation processes.
Chemical Properties
Molecular Formula: C₈H₁₀
Molecular Weight: 106.17 g/mol
Physical Characteristics: Xylene is a clear liquid that is insoluble in water but soluble in organic solvents like alcohol and ether. It has a low boiling point and evaporates quickly from soil and water surfaces.
Safety Considerations
Xylene is flammable and poses health risks, including skin irritation and respiratory issues upon inhalation. Proper handling and safety measures are essential when working with this chemical in industrial and laboratory settings.
In summary, xylene (CAS 1330-20-7) is a versatile chemical with significant applications across various industries, particularly in manufacturing and research, while also requiring careful management due to its hazardous nature.
