Vapor pressures for the main component of the biodiesel - methyl oleate were measured by using the static method. For this purpose, a new setup for vapor pressure measurements in the range (0.1 to 1000) Pa and the elevated temperatures up to 450 K has been designed and tested using the reference materials benzoic acid and naphthalene. Absolute vapor pressures and sublimation (vaporization) enthalpies for the tested compounds were in a good agreement with the most reliable literature data.
