Vapor Pressure Determination of the Aliphatic C5 to C8 1-Alcohols

Abstract

A precise static method is used to measure vapor pressures of 1-pentanol, 1-hexanol, 1-heptanol, and 1-octanol from 298.15 up to the boiling points of these alcohols. The vapor pressure data are correlated with the Antoine and Wagner equations. From the measured vapor pressures, the enthalpies of vaporization are calculated. The results are compared with literature values.
