    Toluene - Thermophysical Properties

    Toluene, C6 H5 -CH3, is a clear colorless liquid, highly flammable with a sweet, pungent aromatic odor.

    Toluene is less dense than water and is slightly soluble in water . Hence it floats on water . Toluene vapor is heavier than air. Toluene may be toxic by inhalation, ingestion or skin contact.

    Toluene is present in crude oils and is a product of oil-refining processes, thus it is used in aviation and automotive fuels. It is also used as a solvent, and to make other chemicals.

    The phase diagram of toluene is shown below the table.

    Chemical, physical and thermal properties of toluene :
    Values are given for liquid at 25 oC (77 oF, K) and 1 bara, if not other phase, temperature or pressure given.
