ABSTRACT
Vapor pressures of five saturated fatty acid ethyl esters (FAEEs), ethyl hexanoate (or ethyl caproate), ethyl octanoate (or ethyl caprylate), ethyl decanoate (or ethyl caprate), ethyl dodecanoate (or ethyl laurate), and ethyl tetradecanoate (or ethyl myristate), were measured at pressures from 1 Pa to 180 kPa and temperatures from (253.15 to 463.15) K using a static apparatus. These esters are a light fraction present in biodiesel derived from palmist oil and copra oil (Ballerini and Alazard-Toux, Les biocarburants; IFP Publications: Paris, 2006). The experimental data (P T) were smoothed using the Antoine equation and compared with the available literature values. The molar enthalpies of vaporization at the mean temperature of the experimental range were derived from the Clausius Clapeyron equation. From these results the standard enthalpies of vaporization at T = 298.15 K were calculated.
