What is vapor pressure toluene?
-139.36. °F. Vapor (saturation) pressure. 0.0038.
What is the vapour pressure of toluene at 30 C?
36.7
At 30.0°C the vapor pressure of pure toluene and pure benzene are 36.7 and 118.2 torr, respectively.
Is toluene a condensing vapour?
The experimental observations demonstrate that the condensation mode of a toluene vapour on a Si surface is dropwise while an octane vapour condenses on a Si surface as a liquid film.
What is the heat of formation of toluene?

Why is toluene used as a solvent?
Toluene is a very good solvent because, unlike water, it can dissolve many organic compounds. In many commercial products, toluene is used as a solvent that is present in paint thinners, nail polish remover, glues, and correction fluid.
What are the properties of toluene?
Pure toluene (melting point, -95° C [-139° F]; boiling point, 110.6° C [231.1° F]) is a colourless, flammable, toxic liquid, insoluble in water but soluble in all common organic solvents. Its chemical formula is that of methylbenzene, C6H5CH3.
Why is toluene a better solvent than benzene?
[1] Because the methyl group has greater electron-releasing properties than a hydrogen atom in the same position, toluene is more reactive than benzene toward electrophiles.
What kind of solvent is toluene?
Toluene is an aromatic hydrocarbon composed of a benzene ring linked to one methyl group. Toluene is used a solvent or as a chemical intermediate in various industrial applications. Rapid inhalation of high concentrations of toluene can cause severe neurological complications.
Why is vapour pressure important?
In assessing hazards, it is very important to know the vapour pressure of a substance. The vapour pressure is the pressure at which a liquid and its vapour are in equilibrium at a given temperature. The vapour is said to be “pushing” against the atmosphere….Vapour Pressure.
| Chemical | Class | Vapour Pressure at 20°C |
|---|---|---|
| Water | NR* | 0.02 atm |
What is the thermophysical properties of toluene?
Toluene – Thermophysical Properties. At the critical point there is no change of state when pressure is increased or if heat is added. The triple point of a substance is the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium.
Is toluene heavier than air?
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.
