Physical Properties
- Appearance: Colorless liquid with a characteristic aromatic odor.
- Density: 0.867 g/cm³.
- Boiling Point: 110.6°C.
- Melting Point: -95°C.
- Solubility: Insoluble in water but soluble in organic solvents like ethanol and ether.
- Flash Point: 4°C.
- Auto-ignition Temperature: 480°C.
Chemical Properties
- Reactivity: More reactive than benzene due to the electron-donating effect of the methyl group.
- Reactions: Easily undergoes nitration (e.g., to form TNT), sulfonation, and halogenation.
- Stability: Stable under normal conditions but highly flammable.
Uses
- Solvent: Widely used in paints, lacquers, adhesives, and as a solvent for resins and gums.
- Chemical Synthesis: Used as a precursor for benzene, TNT, benzoic acid, and other organic compounds.
