A method was devised to evaluate latent heats of vaporization from quasi-isothermal isobaric analysis data. The procedure
requires the recording of at least two diagrams: one for the investigated liquid, and the other for a standard liquid with
a known latent heat of vaporization. Use of the method to determine the heats of vaporization of some alcohols, with water
as standard liquid, led to results close to those previously reported in the literature.
The main advantage of the procedure consists in the fact that it requires only small amounts of sample (5–10 mg).
