1,4-xylene

1,4-xylene is an aromatic hydrocarbon compound with the molecular formula C8H10 and CAS number 106-42-3. It belongs to the xylene isomer family, featuring a benzene ring with two methyl groups positioned at the 1 and 4 positions (para-xylene). With a molecular weight of 106.16 g/mol, this flammable liquid is commonly used as an industrial solvent and chemical intermediate in various manufacturing processes.

1,4-xylene is a colorless liquid at room temperature with a characteristic sweet aromatic odor. It has a boiling point of approximately 138°C and a melting point of 13°C. The compound is practically insoluble in water but readily dissolves in most organic solvents including alcohols, ethers, and other hydrocarbons. It has a density lower than water and exhibits moderate volatility at ambient temperatures.

1,4-xylene serves primarily as a solvent in industrial applications including paints, coatings, adhesives, and printing inks. It is extensively used as a chemical intermediate in the production of terephthalic acid, which is essential for manufacturing polyethylene terephthalate (PET) plastics and polyester fibers. Additionally, it finds application in the pharmaceutical industry, rubber processing, and as a component in various chemical synthesis processes.

1,4-xylene requires careful handling due to its flammable nature and potential health hazards. Always wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection when necessary. Work in well-ventilated areas or under fume extraction systems to prevent vapor accumulation. Keep away from ignition sources, hot surfaces, and oxidizing materials. Avoid skin contact and inhalation of vapors during handling operations.

1,4-xylene must be stored in tightly sealed containers in cool, dry, well-ventilated areas away from heat sources and direct sunlight. Keep containers in secondary containment to prevent spills and maintain storage temperatures below 25°C when possible. Store separately from oxidizing agents, strong acids, and bases to prevent incompatible reactions. Ensure storage areas are equipped with appropriate fire suppression systems and spill containment measures.

In case of skin contact with 1,4-xylene, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. If eye contact occurs, flush eyes with clean water for 15 minutes while holding eyelids open. For inhalation exposure, move the person to fresh air immediately. If ingestion occurs, do not induce vomiting and seek immediate medical attention. Always consult a physician if symptoms persist.

1,4-xylene waste must be disposed of according to local and national hazardous waste regulations as it is classified as a flammable liquid. Contact licensed waste disposal companies for proper collection and treatment. Never pour down drains, sewers, or onto soil. Small quantities may be suitable for solvent recovery or incineration at appropriate high-temperature facilities. Always consult local environmental authorities for specific disposal requirements in your region.

1,4-xylene is classified under ADR transport regulations as Class 3 (Flammable Liquids), Packing Group III. Transport must comply with dangerous goods regulations including proper packaging, labeling with appropriate hazard diamonds, and documentation. Vehicles must carry appropriate emergency equipment and drivers require hazardous materials training certification. Ensure containers are properly secured and compatible with the chemical to prevent leaks during transit.

1,4-xylene is regulated under European REACH and CLP regulations, requiring safety data sheets and hazard classification. It is not currently listed as a Substance of Very High Concern (SVHC). The compound must be labeled with GHS pictograms GHS02 and GHS07, along with the signal word 'Warning'. Industrial users must comply with workplace exposure limits and may require authorization for certain uses depending on quantities and applications.
