Heats of vaporization of then-fatty acid esters

Heats of vaporization at both 25°C and normal boiling points are given for then-fatty acid methyl and ethyl esters and then-alkyl acetates. The validity of the reported heats of vaporization is supported by: (i) their agreement with those estimated by alternate methods, and (ii) the equations correlating heats of vaporization with homolog carbons have the proper slopes (approximately 4.96). Equations also are given for correlating heats of vaporization with boiling points, and boiling points and molar volumes with homolog chainlength.
