The measurement of vapour pressure at different temperatures and the modelization derived from them (Antoine equation) allows us to provide an accurate value at 25 °C: 20.9 mm Hg or 2.79 kPa, in good agreement with values given in handbooks.
The Antoine equation of Nitroethane, determined in the range of 55 to 114 °C (its boiling temperature) has been found to be:
log p = 7.175154 - 1435.402/(t +220.184) with p in mm Hg and t in °C
The extrapolation of this equation at 25°C provides a value of 20.93 mm Hg, which is in good agreement with the value given in a handbook (20.8 mm Hg).
