Additional information

Different studies have been performed for the determination of the vapor pressure of 2 -nitropropane; all are of good quality, made on a pure substance. The Antoine equation has been determined and gives a good prediction of the vapour pressure of 2-nitropropane at different temperatures: logPmmHg = 7.081995 - 1422.122/(t + 218.258) with PmmHg = vapour pressure expressed in mm Mercury and t = temperature in °C.
