What is the vapor pressure of n-heptane?
In this paper, we report 43 vapor pressures over the temperature and pressure range from (371.6 K, 102 kPa) to (537.2 K, 2621 kPa), which is about 3 K and 113 kPa below the critical point of n-heptane, and give an equation for use between the triple point and the critical point.

Is heptane a liquid at room temperature?
However, the simplest type are called “alkanes”. Alkanes have the formula CnH2n+2, where n = 1,2,3 etc.. For example for n=1 we have CH4, for n=2 we have C2H6 etc…..Hydrocarbons (Alkanes)
| Formula (state at room temperature) | Name | |
|---|---|---|
| C7H16 (liquid) | heptane | hept = 7 |
| C8H18 (liquid) | octane | oct = 8 |
| C9H20 (liquid) | nonane | non = 9 |
Is N heptane an alkane?
Heptane or n-heptane is the straight-chain alkane with the chemical formula H3C(CH2)5CH3 or C7H16, and is one of the main components of gasoline (petrol). When used as a test fuel component in anti-knock test engines, a 100% heptane fuel is the zero point of the octane rating scale (the 100 point is 100% iso-octane).
What is the balanced equation for the combustion of heptane?
The balanced equation is C7H16+11O2→7CO2+8H2O .
At what temperature does n-hexane evaporate?
It is a colorless liquid, odorless when pure, and with boiling points approximately 69 °C (156 °F)….Hexane.
| Names | |
|---|---|
| Melting point | −96 to −94 °C; −141 to −137 °F; 177 to 179 K |
| Boiling point | 68.5 to 69.1 °C; 155.2 to 156.3 °F; 341.6 to 342.2 K |
| Solubility in water | 9.5 mg L−1 |
| log P | 3.764 |
Why does hexane evaporate fast?
Hexane reached a lower minimum temperature than heptane. This means that hexane evaporated more quickly than heptane. Hexane and heptane have very similar structures—they are both nonpolar hydrocarbons consisting of C—C and C—H bonds.
How fast does heptane evaporate?
For hexane, heptane and decane droplets this value is approximately 120 ms at room temperature and becomes smaller for higher air temperatures due to the temperature dependence of the air viscosity.
