The molar heat capacities and enthalpies of melting of the even hnear alkanoic acids from
octanoic to eicosanoic were determined Measurements were made with an automatic adiabatic
calonmeter in the temperature range 80 K to several kelvms above the triple-point temperature
The triple-point temperature fitted as a function of the total number of carbon atoms result in a
convergence temperature of (414.6 ± l 0) K for long chain length The thermal properties of the
even alkanoic acids from ethanoic to eicosanoic are reviewed
