Abstract: The melting temperatures of four fatty alcohols, 1-dodecanol, 1-tetradecanol, 1-hexadecanol, and 1-octadecanol, were measured at atmospheric pressure using a μDSC calorimeter and at higher pressures (up to 80 MPa) thanks to a dedicated microscope. The solid–liquid phase diagrams of six binary mixtures formed by these fatty alcohols, namely, 1-dodecanol + 1-tetradecanol, 1-dodecanol + 1-hexadecanol, 1-dodecanol + 1-octadecanol, 1-tetradecanol + 1-hexadecanol, 1-tetradecanol + 1-octadecanol, and 1-hexadecanol + 1-octadecanol systems, were also measured using high pressure microscopy within the range of 0.1 MPa to 80 MPa. In addition, the phase diagrams of the 1-dodecanol + 1-tetradecanol, 1-tetradecanol + 1-hexadecanol, and 1-hexadecanol + 1-octadecanol systems were also measured by DSC in order to compare the results obtained from the microscopy. On the basis of the experimental data, it could be concluded that the behavior of the phase diagrams is slightly affected by the pressure, even within very large pressure ranges such as the ones studied in this work
