Diagram of the installation used in this work. 6: regulator, 11: carving cover, 13: electric engine, 16: counterweight, 18: mercury, and 19: lubricant. The other elements are described in the text.
diagram of liquid-to-solid equilibrium of benzene. Solid line: plot of the curve of Eq. (9) representing the data. The upper diagram compares our work with theory: “o” signs: data site shown in Table I, “∗” signs: equilibrium data obtained upon solving Eqs. (7) and (8) with our data used as parameters. The lower diagram compares our work with previous data: “×” signs: previous data (Ref. 11), “+” signs: previous data (Ref. 8), “◇” signs: previous data (Ref. 2).
Molar volume discontinuity as function of temperature. “o” signs: data sites obtained upon solving Eqs. (7) and (8) with our data used as parameters. Solid line: plot of the line of Eq. (11) fitted to the data sites. “+” signs: previous data (Ref. 8).
Molar enthalpy change of solidification as function of temperature. “o” signs: data sites for the enthalpy change corresponding to our data shown in Table I. Solid line: plot of the cubic curve of Eq. (13) fitted to the data sites.
A diagram of the isobar which is the curve . The vertical line sets a limit between the liquid and solid regions and the horizontal line is the liquid-to-solid transition line. Curve extends continuously and naturally the liquid properties and intersects the line at where , which is taken as the theoretical limit of liquid metastability. See text.
A diagram of the experimental (“o” signs) and theoretical (“∗” signs) limits of liquid metastability as functions of the liquid-to-solid solidification temperature . The solid and dashed lines are fitted to the experimental and theoretical limits of liquid metastability data, respectively.
Liquid-to-solid equilibrium observed data for benzene. Ten results out of the total number of runs performed are shown. Solidification pressure is in MPa and temperature in K.
