Toluene is a colorless, water-insoluble aromatic hydrocarbon commonly used as an industrial solvent and chemical feedstock.
🏭⚗️ Production
It is primarily obtained from the distillation of petroleum and coal tar during refining processes.
🔬 Properties
The chemical formula is C₇H₈ with a molar mass of approximately 92.14 g/mol. It is a clear, volatile liquid with a characteristic sweet smell, low water solubility, and high flammability. It has a boiling point of about 110.6 °C and is moderately dense.
🧪 Applications
Toluene is widely used as a solvent in paints, coatings, adhesives, and inks. It serves as a raw material in the manufacture of benzene, trinitrotoluene (TNT), and other chemicals. It is also used as a fuel additive and in laboratory chemical reactions.
⚠️ Safety
Toluene is toxic if inhaled or ingested in large amounts, causing nervous system effects like headaches, dizziness, and long-term exposure risks. It is highly flammable and should be handled with adequate ventilation, flame-proof equipment, and personal protective gear such as gloves and respirators. Store in a cool, well-ventilated area away from ignition sources.
