International audienceThe physico-chemical properties of the levo- and dextrorotatory menthol isomers as well as the corresponding racemic compound were studied using X-ray single-crystal or powder diffraction and differential scanning calorimetry experiments. As a result, the not yet determined crystal structure of DL-menthol was solved. Moreover, the stable and metastable experimental temperature-composition phase diagrams of the L-menthol/D-menthol binary system were determined. The thermodynamic relative stability of the different menthol polymorphs was also established. The present paper provides new physical, chemical and thermodynamic data of L-, D- and DL-menthol and offers new insight into their polymorphism as well as into the levorotatory-dextrorotatory menthol interactions. Both the thermodynamic and crystallographic approaches demonstrate unambiguously that racemic menthol is a racemate

“…The metastable extensions of these loops end in the theoretical metastable melting points of the pure substances corresponding to a phase that is assumed to be isomorphous with the phase for which the extension of the loop is done. To estimate the fcc and bcc metastable melting points of the AMP and PG metastable phases, the narrow stable [C $ #L] and [C ' #L] branches in the AMP/PG system were extrapolated to X"1 and X"0, respectively, by means of a simple procedure in terms of the equalGibbs-curve (EGC) method (28,29). The values of the metastable points determined are summarized in Table 1.…”

“…Therefore the solidus was obtained by calculation, using the LIQFIT method. (4,11,12) LIQFIT is an iterative procedure for phase-diagram calculations, in which the liquidus is made to pass through a set of experimental liquidus points. Apart from the experimental liquidus data, the input for LIQFIT consists of the thermodynamic properties of the pure substances and the excess Gibbs energy of either the mixed crystalline state (G E, s ) or the liquid state (G E, l ).…”

The melting behaviour of binary mixed crystalline materials was measured with adiabatic calorimetry. The experimental results (heat capacity against temperature graphs) are explained in terms of a model that is based on the assumption that the inhomogeneity of the materials can be described by a Gaussian distribution function. Although this model, called ULTRACAL, has only one adjustable parameter, it is capable of reproducing the experimental data with a good degree of accuracy, as demonstrated for various samples of (1,4-dichlorobenzene + 1,4-dibromobenzene). ULTRACAL thus provides a link between the adiabatic calorimetry data and the solid-liquid Tx phase diagram. It is shown that the model can be used for the determination of phase diagrams. By using ULTRACAL to assess the heat capacity against temperature graphs of five samples, the solid-liquid Tx phase diagram of (1,3,5-trichlorobenzene + 1,3,5-tribromobenzene) was determined.
